Abstract: Power take-off (PTO) systems and methods. A PTO assembly, in one example, includes a first one-way clutch configured to engage with a shaft of a prime mover or an output shaft when the prime mover rotates in a first direction and a second one-way clutch configured to engage with the shaft of the prime mover or the output shaft when the prime mover rotates in second direction which is opposite the first direction. The PTO assembly further includes a first mechanical branch rotationally coupling the first one-way clutch to the output shaft or the prime mover shaft and a second mechanical branch rotationally coupling the second one-way clutch to the output shaft or the prime mover shaft.

Abstract: Systems and methods for a power take-off (PTO) assembly. The PTO assembly, in one example, couples to a shaft and is driven by rotation of the shaft. The PTO assembly includes a disconnect clutch that selectively couples a bi-directional pump to the shaft. The disconnect clutch is passively actuated based on hydraulic system pressure to disengage the disconnect clutch when a prime mover is in operation and engage the disconnect clutch when the prime mover is shut down.

Abstract: An agricultural machine includes a front axle, a rear axle, a power take-off drivably connected with a first motor and a coherent mounting volume. The coherent mounting volume extends axially at least partly between the front axle and the rear axle. The rear axle includes a differential. The differential is covered by the coherent mounting volume and the first motor is located out of the coherent mounting volume.

Abstract: There is provided a work vehicle including a partition wall to keep partition between a first space zone as part of an internal space of the transmission case in which a differential mechanism is located and a second space zone as part of the internal space which is adjacent to the first space zone. An upper space is disposed above the partition wall and configured to allow lubricating oil scooped up from the first space zone by a ring gear to flow in the second space zone. A flow-out path is disposed below the upper space and configured to allow the lubricating oil to flow out of the second space zone to the first space zone.

Abstract: A powertrain arrangement of a working machine, including a first and second electric motor, frame component, and transmission, the first and second electric motor being connected to the transmission for transmitting torque. The frame component forms a receiving space, in which the first and second electric motor and the transmission are accommodated. The frame component has a rear axle casing section configured to rotatably bear a universal-joint shaft connecting the transmission to a rear axle. The frame component has a top-side frame section, which is arranged adjacent to a cab floor in a vertical direction. The first and second electric motor are arranged next to each other in a transverse direction and at least partially at a same level in the vertical direction. The first and second electric motor are arranged above the rear axle casing section and below the top-side frame section in the vertical direction.

Abstract: A modular drive assembly may include an electric motor, a housing at least partially enclosing the motor, an electronic connection assembly configured to electrically couple the electric motor to a host device, and an accessory attachment assembly configured to mechanically couple the modular drive assembly to an accessory to operate a working assembly of the accessory using only electrical power provided from the host device. The accessory attachment assembly may be configured to be releasably attached to the accessory and at least one other accessory of a different type than the accessory.

Abstract: A method and system for operating a transmission that includes a power take off is described. The transmission selectively delivers mechanical power to the power take off from one of two electric traction motors via selective engagement of either a first or a second power take off clutch based on drive mode. The transmission also allows for powershifting between a first and second operating gear.
