ABSTRACT:
An articulated battery-powered electric tractor includes front and rear frame members which are pivotally connected for movement about a substantially vertical axis. A hydraulically-actuated articulation apparatus pivots the front and rear frame members with respect to each other. Wheels support the frame members for travel over the ground. A power-take-off shaft is mounted to the front frame member and is used for driving implements. Electric energy is stored in batteries which are mounted to the rear frame member. The first electric motor is mounted to the rear frame member and is used to drive the tractor wheels. A second electric motor is mounted to the front frame member and is used to drive the power-take-off shaft and the hydraulic articulation apparatus.
