An electric work vehicle includes a housing, a motor to drive a wheel, the motor being supported by the housing, a gearing including a plurality of gears, a locking assembly including a shaft, a first actuator connected to a first end of the shaft, the first actuator being structured to receive a manual operation from a user, and a second actuator connected to a second end of the shaft, the second actuator being controlled by a controller. The motor is connected to the gearing to drive to the wheel. Each of the first actuator and the second actuator are structured to move the shaft to lock the gearing.

An electric work vehicle includes a rear housing, a first motor to drive a first rear wheel, the first motor being supported by the rear housing, and a second motor to drive to a second rear wheel, the second motor being supported by the rear housing. The first motor is connected to a first gearing to drive the first rear wheel. The second motor is connected to a second gearing to drive to the second rear wheel. An outermost portion of the first gearing is located inside of the first motor in a left-right direction of the vehicle. An outermost portion of the second gearing is located inside of the second motor in the left-right direction of the vehicle.

An electric work vehicle includes a rear housing, a first motor to drive a first rear wheel, the first motor being supported by the rear housing, a second motor to drive a second rear wheel, the second motor being supported by the rear housing, a third motor to drive a Power Take-Off (PTO) through a PTO input shaft connected to the third motor, the third motor being supported by the rear housing, and a fourth motor to drive a hydraulic pump, the fourth motor being supported by the rear housing. Each of the first motor, the second motor, the third motor, and the fourth motor are liquid cooled. The rear housing houses a lubrication oil. Each of the first through fourth motors is connected to respective ones of first through fourth gearings which include gears axially aligned with the first through fourth motors.

An electric work vehicle includes a rear housing, a gear casing, a first motor to drive a first rear wheel, the first motor being supported by the rear housing, a second motor to drive a second rear wheel, the second motor being supported by the rear housing, a third motor to drive a first electric work vehicle component other than a wheel, the third motor being supported by the rear housing, and a fourth motor to drive a second electric work vehicle component other than a wheel, the fourth motor being supported by the rear housing. The rear housing is wider than the gear casing in a left-right direction of the electric work vehicle. The rear housing houses the first motor, the second motor, the third motor, and the fourth motor. The gear casing houses first gears and second gears.

A residue processing system for an agricultural harvester includes a chaff mill for processing a stream of chaff containing weed seeds, and a drive system for powering the chaff mill. The drive system includes a gearbox having (i) an input shaft that either directly or indirectly receives power from an engine or other power source of the agricultural harvester, and (ii) an output shaft that is either directly or indirectly connected to a rotor of the chaff mill for rotating the rotor. The gearbox is configured to selectively rotate the output shaft at at least two different speeds such that the rotor of the chaff mill can be rotated at at least two different speeds.

Provided is a power take off (PTO) coupling device for a tractor. The PTO coupling device includes: a first coupling part connected to a PTO shaft of the tractor; and a second coupling part detachably coupled to the first coupling part and connected to a power transmission shaft of a working machine. The first coupling part includes an accommodation part in a disc shape and having an accommodation space with openings formed in the accommodation part, and a PTO connection part on the front surface of the accommodation part to be fixed to the PTO shaft. The second coupling part includes one or more insertion members formed to be inserted into the openings and inserted into the accommodation space through the openings, and a power transmission connection part fixed to the rear surface of the insertion member and connected to the power transmission shaft of the working machine.

An example smart implement includes a power takeoff connector, one or more sensors, a controller, and a communication unit. The power takeoff connector attaches the smart implement to a tractor. The one or more sensors generate implement data. The controller is configured to determine operating parameters based on the implement data from the one or more sensors. The communication unit is configured to communicate with the tractor.

A pull-type harvester has a cutterbar made of a plurality of rotary cutters. The mower includes a middle section and a right section pivotably attached to the middle section and a left section pivotably attached to the middle section such that the cutterbar is folded between an operational configuration and a transport configuration A drive train for powering the cutbar includes a primary gear box, a middle shaft section driven by the primary gear box, the middle shaft section leading to a middle gear case driving the rotary cutters in the middle section, a right shaft section driven by the primary gear box, the right shaft section leading to a right gear case driving the rotary cutters in the right section, and a left shaft section driven by the primary gear box, the left shaft section leading to a left gear case driving the rotary cutters in the left section.
