Abstract
An agricultural vehicle is described having a chassis and a cab mounted on the chassis. The fore end of the cab is mounted on the chassis for pivotal movement about a transverse axis but is prevented from moving relative to the chassis in a vertical plane. The aft end of the cab is resiliently supported on the chassis by springs and is connected to the chassis by means of a linkage, preferably a Watts linkage, that permits movement of the aft end of the cab in a vertical direction towards and away from the chassis while preventing transverse movement of the aft end of the cab.
