Abstract
An electric rider vehicle control system is disclosed which includes a dead man brake that is normally set to prevent coasting, and controls which release the brake and permit normal transport operation of the vehicle at multiple speeds by an operator on the operator's platform. The controls also include a selector switch for selecting between such normal operation and another mode in which the brake is held in a release position by an electrical solenoid, the first controls are disabled or bypassed, and the propulsive drive is operated by jogging control switches mounted on the sides of the vehicle for convenient manipulation by an operator walking alongside. An adjustable hydraulic snubber also is provided to control brake application.
