In one aspect, an agricultural harvester may include a harvesting implement having a belt support assembly configured to support a conveyor belt of the harvesting implement as the conveyor belt moves relative to the belt support assembly. The system may also include a sensor provided in operative association the belt support assembly, with the sensor being configured to detect a parameter indicative of a force exerted on the belt support assembly as the conveyor belt moves relative to the belt support assembly. Furthermore, the system may include a controller communicatively coupled to the sensor, with the controller being configured to monitor the amount of the plant materials entering the harvester based on measurement signals received from the sensor.

A harvesting assembly for harvesting a crop including a cutting knife configured to provide cut crop and a draper platform including a first side draper and a second side draper. A crop auger assembly includes a first auger disposed at the first side draper and a second auger disposed at the second side draper, wherein the first auger and the second auger each include a cylinder having a surface, a flight extending from the surface, and a plurality of fingers extending from the surface and beyond an exposed edge of the flight, wherein the crop auger rotates about an auger axis. A feed drum is disposed at a center draper wherein the feed drum includes a plurality of fingers.

An agricultural harvester may include a system for determining the residue yield of plant materials being ingested by a harvesting implement of the harvester. A controller of the system may be configured to determine the weight of the quantity of plant materials being ingested by a harvesting implement of the harvester based on measurement signals received from the plant yield sensor. The system may be configured to determine the weight of the quantity of crop materials removed from the quantity of harvested plant materials based on measurement signals received from the crop yield sensor. The system may be configured to determine the residue yield value by comparing the determined weight of the quantity of plant materials and the determined weight of the quantity of crop materials.

A row unit assembly for use with a corn harvester includes a first drive having an output shaft, a stalk roll that extends along a first axis and rotates about the first axis via the output shaft of the first drive. A second drive rotates a first drive member about a second axis that is substantially perpendicular to the first axis. A first conveyor extends around the first drive member and moves about the first drive member in response to rotation of the first drive member. A third drive rotates a second drive member about a third axis that is substantially parallel to the second axis. A second conveyor extends around the second drive member and moves about the second drive member in response to rotation of the second drive member.

A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

A cutter blade of a lawn mower includes a blade body and flaps. The blade body includes a shape with a sweepback angle inclined in a reverse-rotation direction of the cutter blade. The flap pivotal axis is provided along a blade edge without intersecting with a blade rotational axis. A flap pivotal axis is provided at a position offset from a line perpendicular to the blade rotational axis and in parallel to the pivotal axis, in a rotation direction of the cutter blade.

A crop ramp and belt support component for an agricultural harvesting head is provided. The crop ramp and belt support component includes a forward portion, a rear portion, and a belt support portion that are generally planar. The forward portion is inclined relative to the rear portion, and the rear portion extends from the forward portion. The belt support portion is substantially parallel to the rear portion and is configured to extend at least partially below an interior surface of a belt conveyor. The forward portion, the rear portion, and the belt support portion are fabricated as a unitary component.

A harvesting machine includes a main frame, a cutter assembly, and a conveyor system. The cutter assembly is pivotally coupled to the main frame. The cutter assembly includes a cutter bar configured to sever crop material adjacent to the ground and a cutter frame configured to support the cutter bar for pivotal movement relative to the main frame. The conveyor system is coupled to the main frame and configured to convey severed crop material in a rearward direction away from the cutter bar toward a central feed drum of the harvesting machine.

Harvesting machines and agricultural harvesting heads for harvesting machines are disclosed herein. A harvesting machine includes a frame, an elongate reciprocating knife, a conveyor system, a drum conveyor, and a crop deflector. The elongate reciprocating knife is coupled to a forward edge of the frame and configured to cut crop material adjacent to the ground. The conveyor system is supported by the frame and configured to carry cut crop material toward a central portion of the frame and rearward therefrom. The drum conveyor is located directly behind at least a portion of the conveyor system, and the drum conveyor includes an elongate cylindrical drum supported for rotation on the frame about a drum axis and a plurality of elongate fingers that at least partially extend through an outer wall of the cylindrical drum.
