Abstract
A tractor cab suspension system has a single support unit (11) which mounts one end of the cab (10) from a chassis (12) of a tractor. The single support unit (11) acts as a noise isolator and does not allow significant vertical oscillation of the cab relative to the chassis but allows the cab to pivot relative to the chassis in pitch (P) and roll (R) modes. Cab support means (13) is provided at the other end of the cab which supports the cab from the chassis and damps pitching of the cab about the single support. Roll damper means (15) are also provided to damp rolling of the cab about the single support, and a control means (18) extends between the cab and chassis which controls transverse movement of the cab relative to the chassis.
