There is provided a powered device and an energy absorbing device (EAD) for a powered device. The powered device includes an actuator to power a rotatable shaft coupled to a working member, a housing to house the actuator, a structural member to be coupled to the housing, and an EAD. The EAD is disposed between the housing and the structural member. The EAD is to absorb at least a portion of an impact energy of the working member striking an obstacle. Moreover, the EAD is to absorb the portion of the impact energy by being plastically deformed by the portion of the impact energy.

A disc mower for cutting crop material includes a plurality of cutter assemblies attached to a frame. Each of the cutter assemblies includes a respective motor operatively attached to a respective disc for rotating the disc. A cutter controller is operatively coupled to the respective motor of each of the plurality of cutter assemblies for selectively controlling a respective commanded rotational speed of the respective motor of one of the cutter assemblies independently of the respective commanded rotational speed of the respective motor of another of the cutter assemblies. Each of the individual cutter assemblies may be vertically moveable relative to the frame independently of the other of the cutter assemblies.

A work machine comprises, a drive source, a working unit that includes a rotary member rotated by the drive source and performs a predetermined work by rotation of the rotary member, and a control unit that controls the drive source so that output of the rotary member partially takes different values in one rotation of the rotary member.

The mower unit includes a mower deck having a top wall and side walls extending downwards from an outer circumferential edge of the top wall, a rotational shaft extending upwards through the top wall from an inside space formed by the top wall and the side walls, a cutter blade attached to a lower portion of the rotational shaft within the inside space and rotatable together with the rotational shaft, an electric mower motor having an output shaft that can rotatably drive the rotational shaft, and a flywheel rotatable in association with the rotational driving of the mower motor.

A mowing machine may include a central cutting deck generally disposed in a neutral mowing plane and a wing cutting deck pivotable with respect to the central cutting deck. A main gearbox may be connected to a wing gearbox by a wing driveline. The main gearbox may be disposed a sufficient distance forward of the central cutting deck and the wing cutting deck to permit the wing cutting deck to pivot about a hinge in a range of motion without disconnecting the wing driveline from either the main gearbox or the wing gearbox.

A power take-off PTO connection mechanism (100) for mid mounted tools (101) of a utility vehicle (1000 includes three main assembly members: a frame attachment mechanism (108), a vertical moving frame (or cradle) (106), and a PTO assembly (128). The frame attachment mechanism (108) is fixed to the frame of the vehicle or tractor (1000). The PTO connection mechanism (100) of the present invention helps is easy and quick connection of the PTO shaft to a variety of tools (101) with the tractor. The PTO shaft remains in continuous contact with the tool power input once it is moved in an engaged position.
