An electrohydraulic system for a work machine includes a pump, a motor fluidly coupled to the pump, a subassembly driven by the motor, and a rate-control valve fluidly coupled to the pump and the motor. The rate-control valve is movable through a range of positions. A present speed of the motor is proportional to a present position of the rate-control valve. The present position of the rate-control valve is adjustable by varying a current supplied to the rate-control valve. The supply of current to the rate-control valve is adjusted based on the difference between the present speed of the motor and a target speed of the motor.

Roll assemblies for cotton harvesters and associated methods are disclosed. Example roll assemblies may include a unitary component that defines a plurality of slots. Bats and brushes may be removably retained within the slots. The unitary component may include a plurality of lobes with the plurality of slots defined therebetween. A central passage may be formed in a central portion of the unitary component. A shaft having an interlocking shape may be removably received within the central passage. In some implementations, one or more lobes are removably securable to the unitary component. End caps may be received onto the shaft and positioned adjacent to ends of the unitary component to assist in retaining the bats and brushes to the unitary component.

A series-parallel hybrid power cotton picker includes a series-parallel hybrid power system; the series-parallel hybrid system includes an engine, a gearbox, a coupling device, a differential, a generator, battery, a main controller, a walking motor controller, a picking motor controller, a fan motor controller, a packing motor controller, a cotton collection motor controller, and a conveyor motor controller; the engine can transmit the power to the coupling device through the gearbox, and the coupling device couples the power of the engine and the walking motor, and then transmits the power to the wheels through the differential. The present disclosure achieves mechanical decoupling between the various working systems of the cotton picker through distributed electric drive, solving the problems of multiple components, long paths, and inability to adjust operating parameters in real time in traditional cotton picker transmission systems.

Improvements in a palm seed pod puller that uses a lever arm operates through a pivoting fulcrum to increase the mechanical advantage of a user to pull the seed tassel more easily from the stalk with less effort. A spring directed cam applies force to clamp onto the seed tassel and can increase the gripping force as the stalk is being pulled. The cam rotates to increase the clamping force as the stalk is crushed and flattens. The cam allows the stalk to wrap around the cam to increase the contact surface for clamping. The support post is positioned within the tree and around the palm fronds where the end of the post rests against the tree to provide a base for the fulcrum and lever arm to apply forces in the opposite direction of the pulling forces on the seed tassel.

One or more techniques and/or systems are disclosed for accumulating harvested crop that includes an accumulator for a harvester vehicle having a plurality of meter rollers aligned along a first axis and a plurality of beater rollers aligned along a second axis. The first axis is different than the second axis, and one roller of the plurality of beater rollers is aligned along the first axis. The one roller of the plurality of beater rollers aligned along the first axis is coupled with the plurality of beater rollers and not coupled to the plurality of meter rollers.

An accumulator assembly for an agricultural harvester includes an accumulator configured to receive agricultural product from a header of the agricultural harvester via an inlet portion of the accumulator. The accumulator includes a front wall, a rear wall, and a floor. The accumulator assembly also includes at least one auger disposed within the accumulator and extending laterally across the accumulator. Furthermore, the accumulator assembly includes multiple conveying rollers positioned at a bottom of the accumulator, in which the conveying rollers are configured to convey the agricultural product toward a conveying system. A ratio of a maximum longitudinal extent of the accumulator between the front wall and the rear wall along a longitudinal axis of the accumulator assembly to a maximum vertical extent of the accumulator between a top of the inlet portion and the floor along a vertical axis of the accumulator assembly is greater than 0.8:1.

A cotton harvesting system includes one or more cotton quality characteristic sensors, configured to detect a plurality of cotton quality characteristics and to generate cotton quality characteristic sensor data indicative of the plurality of cotton quality characteristics; one or more processors and memory storing computer executable instructions that, when executed by the one or more processors, cause the one or more processors to performs steps. The steps comprising: obtaining the cotton quality characteristic sensor data; determining, for each cotton cluster of a plurality of cotton clusters generated by a cotton harvester, a respective set of cotton quality metrics based on the cotton quality characteristic sensor data, wherein for each respective set, each cotton quality metric corresponds to a different cotton quality characteristic than the other cotton quality metrics of the respective set; and generating a control signal based on at least one respective set of cotton quality metrics.

An outlet assembly for a row unit of an agricultural harvester includes an input portion configured to be coupled to a frame of the row unit. The input portion includes an inlet configured to receive agricultural product and an outlet configured to expel the agricultural product. The outlet assembly also includes an output portion having an inlet configured to receive the agricultural product from the outlet of the input portion and an outlet configured to direct the agricultural product into a duct of an air-assisted conveying system. The output portion and the input portion are at least selectively coupled to one another and configured to at least selectively rotate relative to one another.
