ABSTRACT:
An agricultural vehicle includes a chassis and a cab supported on the chassis by means of a support system which maintains the cab level. The support system comprises two pairs of hydraulic actuators. Each pair of actuators is operative to tilt the cab relative to the chassis about a respective one of two mutually inclined axes. The two actuators of each pair are connected to a common pumping element in such a manner that whenever the volume of hydraulic fluid in one of the actuators in the pair is reduced, the volume of hydraulic fluid in the other actuator of the same pair is correspondingly increased.
