An implement coupler for a work vehicle includes a support frame having a drive opening and an array of electric machine mounts arranged about the drive opening. A gearbox is mounted on the support frame and has a gearbox shaft extending through the drive opening. At least one drive pulley is coupled to the gearbox for rotation. At least one endless member is disposed about the drive pulley for rotation therewith. A first electric machine is mounted on the support frame at a first of the electric machine mounts and having a first input pulley coupled to the drive pulley by the at least one endless member.

A drive shaft (1) includes a telescopic shaft (3) having an outer tubular shaft (9) and an inner tubular shaft (11) inserted slidable into the outer shaft (9). A lubrication system is further provided, including: a lubricant receiving chamber (39) housed in the inner shaft (11); a lubricant distribution block (41) housed in the inner shaft (11); lubricant supply ports (11.9) for supplying lubricant from the lubricant distribution block (41), through a tubular wall of the inner shaft (11), towards a gap between the inner shaft (11) and the outer shaft (9); at least a lubricant transferring duct (47.1; 47.2) from the receiving chamber (39) to the distribution block (41). wherein the supplying ports (11.9) are distributed in at least two positions offset in direction of the axis (A-A) of the telescopic shaft (3).

A safety guard support for a power take off shaft, the safety guard support: including a bearing; and a retainer ring. The bearing and the retainer ring including corresponding interlocking formations configured to prevent rotation of the bearing relative the retainer ring about a longitudinal axis.

A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

A working vehicle comprises a vehicle body, a quick hitch, a working implement connected to the vehicle body via the quick hitch, and a linkage interposed between the quick hitch and the vehicle body. The linkage is movable to raise and lower the quick hitch so as to locate the quick hitch at an optional height. The quick hitch can be inclined to a certain degree in a pitching direction of the vehicle body at the optional height defined by the linkage.

An agricultural implement includes a tow bar assembly for towing the implement with a towing vehicle. The tow bar assembly includes a tow bar mounted to a part of the implement by a first pivot bearing so as to be pivotable about a first vertical axis. The tow bar assembly includes an arm parallel with and spaced vertically below the tow bar. The arm is attached to the part of the implement by a second pivot bearing so as to be pivotable about a second vertical axis that is coaxially located with the first vertical axis.

The drive shaft (1) comprises end universal joints (5, 7) with accident-preventing end protections (19). Each accident-preventing end protection comprises a lubricant reservoir, delimited radially inwardly by a sleeve (63) of an inner fork (23) of the respective universal joint (5; 7) and radially outwardly by a rigid annular structure of the accident-preventing end protection.

A drive system of a header for an agricultural vehicle. The header includes a plurality of driven devices. The drive system includes a shaft configured for conveying motive power from the agricultural vehicle to the header, a gearbox configured for being located on the header and for transferring motive power to the plurality of driven devices, and a torque damper. The torque damper is operably connected in between the shaft and the gearbox. The torque damper is configured for reducing a magnitude of a torque spike.
