Abstract: A speed and direction control apparatus for a skid steer vehicle of the type having right and left driven wheels which are caused to be operated by variable displacement pumps. The control apparatus is similar to that found in normal highway vehicles in that a steering wheel is provided for controlling the turning of the vehicle and a foot pedal is provided for controlling the speed of the vehicle. One end of each of a pair of push-pull control cable assemblies is used to move the control arms of the variable displacement pumps and the other end of the pair of control cables are in turn secured to a rotatable element which is in turn supported for rotation on a portion of a rotatable steering column. The rotatable element can be rotated by the steering wheel to cause one control arm to be displaced with respect to the other control arm to effect turning of the vehicle.

Abstract: An outrigger support system to provide lateral stability for vehicles such as fire engine ladder trucks employs extensible legs that are angled out sidewardly from the vehicle and movable downwardly into engagement with the ground. The legs are provided with movable lateral extensions on their lower ends to increase lateral stability. Power mechanisms are provided engaging the legs and lateral extensions to move them between retracted and extended positions.
