Abstract
A system and method for controlling the ground speed and enhancing the maneuverability of an off-road vehicle having systems for initially establishing and thereafter automatically returning the hydrostatic transmission to the neutral position, a pedal system interconnected with the neutral location and return system for selectively driving the vehicle in either the forward or the reverse direction, a brake system consisting of a left foot operated left and right turn brake subsystem which enhances the vehicle maneuverability, a right foot operated master brake system which is used to bring the vehicle to a complete hault and for emergencies, and a park brake system which is used to lock the brakes when the vehicle is at rest, a cruise control system which is interconnected with the pedal system and the brake system. The left foot operated turn brake subsystem enables an operator to utilize the turn brakes without the cruise control engaged and without having to take his foot off the forward or the reverse pedal. The cruise interconnections with the service brake and the pedal system provide a plurality of disengagement options for the cruise control system.
