    FIELD OF THE INVENTION
    [001] The present subject generally refers to agricultural harvesters and, more particularly, to a system and method for controlling the spreading of crop residue expelled from a harvester spreader. BACKGROUND OF THE INVENTION
    [002] Axially arranged rotary separation or threshing systems have been used in agricultural harvesters for threshing crops to separate grain from crop residue, also called non-grain material (MOG). Such axially arranged systems typically include at least one cylindrical rotor rotated within a cage or concave part, with the rotor and the surrounding concave part being oriented for the purpose of extending from front to back within the harvester.
    [003] During the operation of the harvester, the harvest material is fed or directed to a circumferential passage between the rotor and the concave part and is carried backwards by a generally helical path through such a passage through the rotation of the rotor according to the grain it is threshed from the harvest material. The flow of crop residue remaining between the rotor and the concave part after threshing is typically discharged or expelled at a rear end or downstream of the rotor. After discharging the threshing system, the crop residue is typically directed to a crop residue distribution system located below and behind the rear end of the rotor. The crop residue distribution system typically includes a whisk or rotary cutter or other device that conducts or cuts the waste into smaller pieces and propels the crop residue back toward an area within the rear end of the harvester, hereinafter invention called a distribution chamber. The harvest waste supplied inside the distribution chamber can be discharged over a field like a windrow or directed to a spreader mounted on or at the rear end of the combine which is operable to spread the waste over a field bundle.
    [004] Combines are typically configured to collect crops with vastly different material properties, which can make controlling the spread distribution and / or spread width of the crop residue discharged from the harvester spreader difficult. For example, light crops, such as wheat, create a low-density residue that is much more difficult to spread over a long distance compared to heavier crops, such as corn, which create a relatively dense residue. To accommodate such different material properties, many conventional spreaders include motors configured to rotate the spreader discs at varying speeds. These engines are typically required to have the ability to rotate spreader discs at a relatively high speed to discharge low density waste widely while also having the ability to rotate spreader discs at a relatively low speed to prevent high waste density are discharged very widely. As such, the variable speed motors used in such conventional spreaders can be relatively expensive. In addition, to prevent the crop residue from being discharged too widely, the speed settings for the spreader discs need to be carefully customized to match the properties of the particular crop material that is collected, which is often a difficult and difficult task. time consuming.
    [005] Consequently, a system and method that are capable of controlling the spreading spread and / or the spreading width of the crop residue without requiring the rotational speed of the spreader discs to be adjusted would be appropriate in the technology. SUMMARY OF THE INVENTION
    [006] The aspects and advantages of the invention will be presented in part in the following description or they can be obvious from the description or they can be learned through the practice of the invention.
    [007] In one aspect, the present matter is directed to a system to control the spreading of crop residue expelled from an agricultural harvester. The system may include a spreader configured to expel crop residue from the combine. The spreader may include at least one spreader disk configured to be rotated about a geometry axis. In addition, the system may include a windrow door that has an internal surface that defines a flow path to direct the crop residue into the spreader. At least a portion of the windrow door can be configured to be moved relative to the spreader to adjust a location in which the crop residue is introduced onto the at least one spreader disc.
    [008] In another aspect, the present subject is directed to a system to control the spreading of crop residue expelled from an agricultural harvester. The system may include a spreader configured to expel crop residue from the combine. The system can also include a windrow door that has an internal surface that defines a flow path to direct the crop residue into the spreader and a residue divider that extends from the inner surface. The waste divider can be configured to divide the crop residue that flows along the inner surface into at least two separate waste streams.
    [009] In an additional aspect, the present subject is directed to a method for controlling the spreading of crop residue expelled from an agricultural harvester, in which the harvester includes a windrow door and a spreader. The method may include directing a crop residue stream along the windrow door such that the crop residue is introduced onto a spreader spreader disc at a first location and adjusting the crop residue flow direction along of the windrow door in such a way that the harvest residue is introduced over the spreader disc in a second location.

    [024] Reference will now be made in detail to the modalities of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, without limitation of the invention. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, the features illustrated or described as part of one modality can be used with another modality to produce another additional modality. Accordingly, it is intended that the present invention covers all modifications and variations as included as included in the scope of the appended claims and their equivalents.
    [025] In general, the present subject is directed towards a system and method for controlling the spreading of crop residue expelled from an agricultural harvester. In various embodiments, the system includes a spreader and a suitable means of adjusting the location in which the crop residue is introduced onto the spreader discs of the spreader. For example, in one embodiment, at least a portion of the combine's windrow door is configured to be moved relative to the spreader, thereby changing the flow direction of the harvest residue as it travels along the windrow door and into the spreader. In another embodiment, a waste divider is positioned along the inner surface of the windrow door in such a way that the harvest waste stream is divided into at least two separate streams.
    [026] It should be noted that, by adjusting the location in which the crop residue is introduced onto the spreader discs, the spreading distribution and / or the spreading width of the crop residue is also adjusted. For example, by introducing the crop residue in a location directly between the rotational geometrical axes of the spreader discs, the residue may be traveling at a relatively high speed when it is expelled from the spreader on the outer perimeter of the discs, thereby resulting in a large width spreading. However, if the crop residue is introduced onto the spreader discs later from the location directly between the rotational geometry axes, a larger portion of the crop residue may initially come in contact with the spreader discs at a radially external location on the discs. . As such, the crop residue may remain on the spreader discs for a shorter period of time before being expelled, and thus may have a lower outlet speed, thereby resulting in a narrower spreading width. . Additionally, as the material is discharged inertia, which transports it in a linear direction on a tangent with respect to the disc at its last point of contact, it affects the point of introduction which will affect the tangential starting point. This provides a second method by which changing the introduction location affects the spreading distribution.
    [027] Referring now to the drawings, Figure 1 illustrates a simplified side view of an agricultural harvester modality 10. In general, harvester 10 is configured in the same way or similar to any suitable agricultural harvester known in the art. For example, as shown in Figure 1, the harvester 10 includes an axially disposed threshing system 12. As is generally understood, the threshing system 12 includes a cylindrical rotor 14 pivotally supported within a cage or concave part 16 for driving a flow of harvest material in a helical flow path along a circumferential space 18 defined between the rotor 14 and the concave part 16. As the harvest material is moved through the space 18 towards a rear end 34 of the combine 10 (indicated by arrow 20), the harvest (for example, grain, vegetables and / or the like) is separated from the waste (for example, husks, stems and / or the like) and subsequently removed from the threshing system 12. The waste from Harvesting can continue along the helical path and is subsequently discharged through a discharge opening (not shown) defined at a downstream end 22 of the threshing system 12.
    [028] In addition, the combine 10 includes a crop residue delivery system 24 to expel the crop residue from the combine 10. As shown, the delivery system 24 includes a rotating device 26, such as a whisk or a cutter , rotatably supported above a concave container 28. As is generally understood, the rotating device 26 is configured to be rotated at a rapid speed such that the flow of harvest residue from the threshing system 12 is subsequently propelled along a series of shields or inner panels, such as a guide panel 30 (for example, a frame or straw panel) and a windrow door 32, towards the rear end 34 of the harvester 10. For example, as shown in Figure 1, the concave container 28 is angled in such a way that the crop residue is propelled later and upwards from the rotating device 26 into a chamber the distribution 36 where the waste is directed along the guide panel 30 towards the windrow door 32 (indicated by the arrows 38).
    [029] As is generally understood, the top end of the flap door 32 is generally configured to be pivotably or pivotably attached to the guide panel 30. In this way, the flap door 32 is rotated relative to the guide panel 30 between a closed position (indicated by the dotted lines 40), in which the crop residue flowing through the distribution chamber 36 is directed along the windrow door 32 and into a spreader 42 for beam spreading, and a closed position (indicated by the dashed lines 44), in which the crop residue is directed along the windrow door and expelled through a rear opening 46 of the harvester 10 to the windrow.
    [030] Referring now to Figures 2 to 4, an embodiment of a system 100 for controlling the spreading of crop residue expelled from a combine 10 (Figure 1) is illustrated according to the aspects of the present subject. As shown, system 100 generally includes a spreader 102 configured to expel crop residue from harvester 10 and a windrow port 104 configured to direct harvest residue into spreader 102 as it flows through the distribution chamber 36 at the rear end 34 of the combine 10.
    [031] In general, spreader 102 can be configured in the same way or similar to any suitable spreader known in the art. For example, as shown in Figures 2 to 4, spreader 102 is configured as a horizontal spreader and therefore includes two horizontally oriented spreader discs (for example, a first spreader disc 105 and a second spreader disc 106) configured to distribute the crop residue laterally and later on over a field. As is generally understood, each spreader disc 105, 106 can be configured to be rotated about a geometry axis 108 that extends generally perpendicular to the ground. In addition, spreader 102 may also include a spreader cone 110 that extends from the center of each spreader disc 105, 106 (for example, by aligning spreader cone 110 coaxially with geometry axis 108) and a plurality of paddle spreaders or paddles 112 extending radially outwardly from each spreader cone 110. However, in alternative embodiments, it should be noted that spreader 102 may have any other suitable configuration that allows it to function as described herein. invention.
    [032] During the operation, the harvest residue is directed into the spreader 102 (for example, through the inlet 114) and over the rotating spreader discs 105, 106. As spreader discs 105, 106 rotate, the crop residue is accelerated as it slides radially outwardly against each spreader cone 110 and is subsequently discharged from spreader 102 at the outer perimeter of each spreader disc 105, 106. Thus, as indicated above, the location in which the crop residue is introduced over each spreader disc 105, 106 can significantly impact the speed and the tangency point at which the waste is expelled from the spreader 102, thereby affecting the spreading distribution and / or the spreading width of the crop residue.
    [033] For example, as shown in Figure 4, when the crop residue is introduced on the spreader discs 105, 106 between the spreader cones 110 along a reference line 116 that extends between the rotational geometric axes 108 of disks 105, 106 (i.e., central disk location 118 indicated by the solid box), the residue may be in contact with spreader disks 105, 106 for a longer period of time before being expelled than if the residue of harvest had been introduced on spreader discs 105, 106 at a location posterior to reference line 116 (for example, rear disc location 120 indicated by the dashed box). As such, by adjusting the location at which the crop residue comes in contact with spreader discs 105, 106 from central disc location 118 to rear disc location 120, the crop residue can slide radially outward along the spreader disks 105, 106 for a shorter distance before being expelled from the spreader 102, thereby reducing the speed of the expelled crop residue. Similarly, depending on the configuration of spreader 102, the introduction of the crop residue onto spreader discs 105, 106 at a location in front of reference line 116 (for example, front disc location 122 indicated by the dashed box) also may impact the final speed of the expelled crop residue. For example, as shown in Figure 4, in one embodiment, spreader 102 includes a side wall 124 that extends along a portion of the front spreader 102 to prevent the crop residue from being expelled in the forward or forward direction of the combine 10 (indicated by arrow 126). Thus, by introducing the crop residue onto spreader discs 105, 106 at the front disc location 122, the speed of the crop residue that is eventually expelled from the rear of spreader 102 may differ from the speed achieved when the crop residue it is inserted over spreader discs 105, 106 in the central disc location 118 or in the rear disc location 120.
    [034] Still referring to Figures 2 to 4, as indicated above, the revealed system 100 also includes a windrow door 104 configured to define a flow path for the crop residue that runs between the guide panel 30 and the spreader 102 As will be described in detail below, in various embodiments, at least a portion of the windrow door 104 is configured to be moved relative to the spreader 102 in order to adjust the location in which the crop residue is introduced over the discs. spreader 105, 106. For example, by adjusting the position of at least a portion of windrow door 104 in relation to spreader 102, the crop residue stream is directed over spreader discs 105, 106 at the front disc location 122, at the central disc location 118, at the rear disc location 120, or at any other suitable location along the spreader discs 105,106.
    [035] As shown in the illustrated embodiment, windrow door 104 includes a door panel 128 configured to serve as a guide for the crop residue as it flows past a downstream end 130 of the guide panel 30. For example, as shown in Figure 2, the door panel 128 can extend lengthwise between a first end 132 and a second end 134, with the first end 132 of the door panel 128 being coupled to the downstream end 130 of the guide panel 30. As as such, an inner surface 136 of the guide panel 30 and an inner surface 138 of the door panel 128 can generally define a substantially continuous flow path for the crop residue flowing into the dispensing chamber 36 towards the rear end 34 of the combine harvester 10.
    [036] It should be noted that, in various embodiments, door panel 128 can be configured to be pivotally coupled to downstream end 130 of guide panel 30. As such, door panel 128 is rotated relative to the panel guide 30 in order to change the flow direction of the crop residue between the spreader 102 and the rear opening 46 (Figure 1) of the combine 10. For example, as shown in Figure 2, similar to the windrow door 32 described above in reference To Figure 1, door panel 128 is configured to be rotated to a closed position in which the curvature or tangential flow direction of the inner surface 138 of door panel 128 as its second end 134 is directed towards spreader 102. Thus, as the crop residue flows beyond the guide panel 30, it is directed along the inner surface 138 of the door panel 128 towards the spreader 102. Alternatively, the door panel 128 is moved to a open position in which the second end 134 of the door panel 128 is rotated in the opposite direction to the spreader 102 in order to define the rear opening 46 (Figure 1) of the harvester 10. As such, the harvest residue that flows along the windrow door 104 is directed through the rear opening 46 and over a field like a windrow.
    [037] Additionally, windrow door 104 also includes a baffle panel 140 coupled to the second end 134 of door panel 128. As such, baffle panel 140 can generally form an extension of the flow path for the crop residue that runs along windrow door 104. For example, as particularly shown in Figure 2, deflector panel 140 is configured to extend from door panel 128 in such a way that the crop residue flowing beyond the second end 134 of the door panel 128 is directed along an inner surface 142 of the deflector panel 140 and into the interior of the spreader 102. In this way, the inner surfaces 138, 142 of the panels 128, 140 can generally define a continuous flow path for the crop residue as it flows along the windrow door 104 between the guide panel 30 and the spreader 102.
    [038] In various embodiments, the baffle panel 140 can be configured to be pivotally coupled to the second end 134 of the door panel 128 to allow the flow direction of the crop residue to be changed as it enters the spreader 102. For example , as shown in the illustrated embodiment, the deflector panel 140 is pivotally coupled to the door panel 128 via a pivot pin 144 or any other suitable articulated and / or rotational fixing mechanism. As such, the orientation of the deflector panel 140 in relation to the door panel 128 and / or the spreader 102 is adjusted in order to change the trajectory of the crop residue flowing into the spreader 102.
    [039] For example, as shown in Figures 2 and 3, the baffle panel 140 can be initially positioned in a location in relation to the door panel 128 and / or spreader 102 so that the crop residue flowing along the inner surface 142 of deflector panel 140 is directed over spreader discs 105, 106 at central disc location 118 (Figure 4). However, by changing the orientation of the deflector panel 140, the location in which crop residue is introduced on the spreader discs 105, 106 is adjusted. For example, as shown in Figures 2 and 3, the baffle panel 140 is later rotated relative to the door panel 128 to a rear baffle position (indicated by dashed lines 146) in which the crop residue stream is directed along the surface. internal 142 of the baffle panel 140 and on the spreader discs 105, 106 at the rear residue location 120 (Figure 4). Alternatively, the baffle panel 140 is rotated forward relative to the door panel 128 to a front baffle position (indicated by dashed lines 148) in which the crop residue stream is directed along the inner surface 142 of the baffle panel 140 and on spreader discs 105, 106 at the front residue location 122 (Figure 4).
    [040] It should be noted that, in various embodiments, the position of the deflector panel 140 in relation to the door panel 128 and / or spreader 102 is configured to be manually adjusted. For example, in one embodiment, the position of the deflector panel 140 is adjusted by means of a spring-loaded pin (not shown) and / or any other suitable manually adjustable positioning mechanism. In such an embodiment, a combine operator 10 can manually adjust the location of the spring-loaded pin and / or other positioning mechanism in order to move the deflector panel 140 relative to the door panel 128 and / or the spreader 102.
    [041] Alternatively, the position of the deflector panel 140 is configured to be automatically adjusted. Specifically, in various embodiments, a suitable electronically controllable actuation device is operatively coupled to the deflector panel 140. For example, as shown in Figure 3, an electric motor 150 is coupled to the deflector panel 140 on the geometric axis of articulation defined between the baffle panel 140 and door panel 128. In such an embodiment, electric motor 150 is coupled to a suitable controller to allow the operator to automatically adjust the position of baffle panel 140 from inside the operator's cabin. In additional embodiments, any other suitable actuating device, such as a linear actuator, hydraulic or pneumatic cylinder or a mechanical arrangement (for example, a four bar connection), is used to automatically adjust the position of the deflector panels 140.
    [042] It should be noted that such automatic control of the position of the deflector panel 140 may allow the operator of a combine 10 to make fine adjustments to the spreading spread and / or spreading width of the crop residue as the combine 10 is being operated. For example, if the current spreading width of the crop residue is too narrow, the operator can automatically adjust the position of the deflector panel 140 in relation to the door panel 128 and / or the spreader 102 in order to change the flow direction of the crop residue into spreader 102 in a way that increases the spreading width.
    [043] Referring now to Figures 5 and 6, a variation of the deflector panel 140 shown in Figures 2 to 4 is illustrated according to aspects of the present subject. As shown, instead of being configured as a single panel or flap, the baffle panel 140 may comprise two or more baffle flaps 152, 154 that extend outwardly from the door panel 128. For example, as shown in Figures 5 and 6, the baffle panel 140 includes a first baffle flap 152 and a second baffle flap 154, with each baffle flap 152, 154 being pivotally coupled to door panel 128. In such an embodiment, baffle flaps 152, 154 can be configured to be independently rotated with respect to door panel 128 to allow the flow direction of the crop residue to be varied over the width of the baffle panel 140.
    [044] For example, as shown in Figure 5, the first deflector flap 152 is configured to control the flow direction of a left portion or first portion of the crop residue (indicated by dashed box 156) as it is directed along the door windrow 104 and over the first spreader disc 105. Similarly, the second baffle flap 154 is configured to control the flow direction of a right portion or second portion of the crop residue (indicated by dashed box 158) as directed along windrow door 104 and on the second spreader disc 106. Thus, as shown in Figure 6, by varying the position of the first deflector flap 152 in relation to the door panel 128, the location in which the first portion 156 of the crop residue is introduced over the first spreader disc 105 (indicated by the dashed box 160 in Figure 6) and is adjusted both radially along the first spreader disc 105 q as to the location where the second portion 158 of the crop residue is introduced into the second spreader disc 106 (indicated by the dashed box 162 in Figure 6).
    [045] Such independent control of each baffle flap 152, 154 can in general further facilitate the fine adjustment of the spread distribution and / or spread width of the crop residue that is expelled from the combine 10. For example, in the case where the spreading width of the crop residue needs to be adjusted along the right side of the combine 10 (for example, the side of the combine 10 along which the second spreader disc 106 is located), the position of the second deflector flap 154 is adjusted in relation to door panel 128 to change the location where the second portion 158 of the crop residue is introduced over the second spreader disc 106. This is particularly advantageous, for example, when a highway or residential property is located adjacent to the collection farm. In such a case, the spreading width of the crop residue that is expelled along the side of the harvester 10 on which the road or residential property is located is reduced to ensure that the residue is not discharged in the path of a vehicle or on land neighbor.
    [046] Additionally, it should be noted that, in modalities in which deflector flaps 152, 154 are configured to be rotated independently of each other, a separate actuation device is associated with each deflector flap 152, 154. For example, as shown in Figure 5, a first electric motor 150 is coupled to the first baffle flap 152 and a second electric motor 151 is coupled to the second baffle flap 154. As such, each motor 150, 151 is separately controlled to adjust the position of each baffle flap 152 , 154. Alternatively, the positions of the deflector flaps 152, 154 can be configured to be manually adjusted in relation to door panel 128 and / or in relation to each other.
    [047] Referring now to Figure 7, another embodiment of a windrow door 104 that is used to control the location in which the crop residue is introduced on the spreader discs 105, 106 of the spreader 102 is illustrated according to aspects of this subject. As shown, instead of including both a door panel 128 and a baffle panel 140, windrow door 104 can simply include a door panel 228 pivotally coupled to downstream end 130 of guide panel 30. In such an embodiment, the door panel 228 is configured to be rotated relative to the guide panel 30 over a range of positions to adjust the flow direction of the crop residue into the spreader 102. For example, as shown in the solid lines of Figure 7, door panel 228 is configured to be positioned relative to spreader 102 in such a way that the crop residue stream is generally directed between spreader cones 110 of spreader 102 (for example, at the disc location center 118 shown in Figure 4). Alternatively, door panel 228 is rotated afterwards (indicated by dashed lines 264) to direct the harvest waste stream towards the rear of spreader discs 105, 106 (for example, at the rear disc location 120 shown in Figure 4 ) or door panel 228 is rotated forward (indicated by dashed lines 266) to direct the crop residue stream towards the front of spreader discs 105, 106 (for example, at the front disc location 122 shown in Figure 4).
    [048] It should be noted that, similar to the modalities described above, the position of the door panel 228 is configured to be manually or automatically adjusted. For example, as shown in Figure 7, in one embodiment, a suitable actuating device, such as an electric motor 150, is coupled to door panel 228 to allow the position of panel 228 to be automatically adjusted.
    [049] Referring now to Figure 8, a variation of door panel 228 shown in Figure 7 is illustrated according to aspects of the present subject. As shown, instead of being configured as a single panel or flap, door panel 228 may comprise two or more door flaps 268, 270 pivotally coupled to guide panel 30. For example, as shown in the illustrated embodiment, door panel 228 includes a first door flap 268 and a second door flap 270, with each door flap 268, 270 being configured to be independently rotated relative to guide panel 30. As such, similar to deflector flaps 152, 154 described above, the position of each door flap 268, 270 is adjusted in relation to the guide panel 30 and / or in relation to another door flap 268, 270 in order to vary the flow direction of the crop residue over the width of the door panel 228. For example, as shown in Figure 8, the position of the first baffle flap 268 is varied (for example, through a first motor 150) to control the location in which the crop residue is introduced over the first spreader disc 105 while the position of the second baffle flap 260 is varied (for example, via a second motor 151) to control the location in which the crop residue is introduced on the second spreader disc 106.
    [050] It should be noted that, as an alternative to rotating at least a portion of the windrow door 104 in relation to the spreader 102, at least a portion of the windrow door 104 is configured to be deflected in order to control the location at which the crop residue is introduced onto spreader discs 105, 106. For example, in several embodiments, windrow door 104 (or a portion thereof, such as door panel 128, 228 or deflector panel 140) is made of a flexible and light material (for example, a flexible plastic or other polymeric material) that has the ability to be flexed or deflected in order to adjust the shape and / or the orientation of the windrow door 104 in relation to the spreader 102. In such an embodiment, a suitable actuating device, such as an actuator or linear cylinder, is used to deflect windrow door 104 in relation to spreader 102.
    [051] Referring now to Figures 9 to 12, in addition to configuring at least a portion of windrow door 104 to be movable relative to spreader 102 or as an alternative to this, the revealed system 100 also includes a waste divider 372 configured to separate the harvest waste stream along windrow door 104 into two or more separate waste streams. In such embodiments, the windrow door 104 is generally configured in the same way or similar to any of the windrow door configurations described above in reference to Figures 2 to 8 or in the same way or similar to any conventional windrow door known in the technical. For example, as shown in the illustrated embodiment, windrow door 104 can in general be configured to extend lengthwise between a first end 374 and a second end 376 and includes an inner surface 378 that defines a generally continuous flow path. for the crop residue flowing along the windrow door 104 between the guide panel 30 and the spreader 102.
    [052] In addition, as shown in the illustrated embodiment, the waste divider 372 can generally be configured to project outwardly from the inner surface 378 of windrow door 104 in order to separate the harvest waste stream directed to the along the inner surface 378 in a first a waste stream 380 and a second waste stream 380. Such a division of the crop residue into separate streams can generally allow the waste to be introduced onto spreader discs 105, 106 at more locations focused, thereby providing increased control of the spreading spread and / or spreading width of the crop residue.
    [053] For example, as shown in Figure 11, in the absence of the residue divider 372, the crop residue is configured to be placed on spreader discs 105, 106 in a central disc location (indicated by dashed box 384) which generally travels the span defined between the rotational geometric axes 108 of the disks 105, 106. However, by dividing the harvest residue into separate waste streams 380, 382, the waste is directed over specific areas of the spreader disks 105, 106. For example, as shown in Figure 11, in one embodiment, the first waste stream 380 is focused on a location adjacent to the rotational geometry axis 108 of the first spreader disc 105 (indicated by box 386) and the second waste stream 382 is focused on a location adjacent to the rotational geometry axis 108 of the second spreader disc 106 (indicated by box 388). In such an embodiment, by introducing a larger portion of the crop residue closest to the rotational geometry axes 108 of the spreader discs 105, 106, most of the crop residue needs to slide radially outward along the discs 105, 106 for an additional distance before being expelled from the spreader 102, thereby increasing the speed of the expelled crop residue.
    [054] In other embodiments, it should be noted that residue divider 372 can be used to direct the crop residue over any other suitable locations along spreader discs 105, 106. For example, by adjusting the door location windrow 104 in relation to the spreader 102, the first and second waste streams 380, 382 can be directed over radially external portions of the spreader discs 105, 106 (indicated by the dashed boxes 390), thereby resulting in a decrease in the speed of the expelled harvest residue. Similarly, by adjusting the position of the waste divider 372 along the length of windrow door 104, a divided distance 389 (Figure 11) defined between the waste streams 380, 382 is increased or decreased. For example, by moving the position of the waste divider 372 shown in Figures 9 and 10 to a location closer to the first end 374 of windrow door 104, the divided distance 389 defined between the waste streams 380, 382 is increased.
    [055] It should be noted that the residue divider 372 can in general have any suitable configuration that allows it to function as described in the present invention. For example, in various embodiments, the waste divider 372 is wedge or pyramid-shaped and, in this way, it can define a divergent width 392. Specifically, as shown in Figure 10, the waste divider 372 is configured to extend in the direction of length between an upstream end 394 and a downstream end 396, with the width 392 of the divider 372 that diverges between the upstream and downstream ends 392, 396. Alternatively, as shown in the embodiment of Figure 12, the divider of residue 372 is configured to define a relatively constant width 392 between its upstream and downstream ends 394, 396.
    [056] Additionally, in various embodiments, the residue divider 372 is configured to extend lengthwise by any suitable distance between the first and second ends 374, 376 of the windrow door 104. For example, as shown in Figures 9 and 10, in one embodiment, divider 372 may extend only partially between the first and second ends 374, 376 of windrow door 104. Alternatively, as shown in the embodiment of Figure 12, divider 372 is configured to extend completely between the first and second ends 374, 376 of windrow door 104.
    [057] This description uses examples to reveal the invention, which includes the best mode, and also to allow any element skilled in the art to put the invention into practice, which includes the production and use of any devices or systems and the execution of any built-in methods. The patentable scope of the invention is defined by the claims and may include other examples that occur for those skilled in the art. Such other examples are intended to be included in the scope of the claims if they include structural elements that do not differ from the literal language of the claims or if they include equivalent structural elements with negligible differences from the literal languages of the claims.
