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.

Abstract: An adjustable height roll-over bar is provided in which the cross-piece is separate from the vertical members. The height of the roll-over bar is adjusted by adjusting the connection between the cross piece and the roll-over bar. The three embodiments for this connection are taught: First, corner brackets are provided and an extension can be added between the vertical member and the corner bracket to increase the height of the roll-over bar. One corner bracket leg is longer than the other to compensate for the difference in horizontal distance between the vertical member and the vertical member plus extension when the vertical members are angled. The same corner brackets can be used at either height simply by flipping the corner bracket end-for-end to adjust the position of the long leg. In the second embodiment, the vertical members and the cross piece each are provided with angled engagement surfaces, preferably 45 degrees.
