Abstract
An operator's platform, a vehicle cab and a forward tractor engine enclosure are pivotally mounted as a unit at a forward pivot point to a tractor frame. These components are suspended at the rear portion of the frame through an integrated suspension system including a coil spring and a shock absorber. A pair of vertical guide members at the rear of the suspended chassis of the vehicle interact with rollers accompanied on laterally projecting arms fastened to the rear section of a tractor chassis to pivot in a vertical plane around forward pivot points while constraining lateral movement of the cab relative to the vehicle chassis.
