The disclosure relates to a quick-release device for a tractor PTO shaft, including a first body having a first outer surface and a second outer surface and a first thickness disposed therebetween; a plurality of slots defined on the first body; a second body having a third outer surface and a fourth outer surface and a second thickness disposed therebetween; and a plurality of extensions extending from the second body, wherein the plurality of extensions are configured to removably engage with the plurality of slots.

A vehicle may operate in a first mode in which an electric motor operates in a forward state such that the rear ground traction members of the vehicle are driven forwardly by the electric motor while a hydraulic pump is powered by the electric motor and may alternatively operate in a second mode in which the electric motor operates in a reversed state such that the rear ground traction members are driven forwardly by the electric motor while the electric motor is operably decoupled from the hydraulic pump by a one-way clutch/bearing ring coupled between the electric motor and the hydraulic pump.
