A four way tilt mechanism (15) for maintaining the super- structure (14) of an off road vehicle generally horizontal while the vehicle is working on uneven terrain is disclosed. The tilt mechanism is very robust and provides independent adjustment of the angle of tilt relative to each of two pivot axes (16, 17). The tilt mechanism (15) incorporates a spherical bearing (37) mounted on a shaft (38) perpen- dicular to the longitudinal pivot axis (16) of the tilt mechanism to eliminate end-play in the joint which forms the longitudinal pivot axis. The longitudinal and transverse pivot axes (16, 17) preferably lie in the same plane so that many of the the forces which are trans- ferred from the superstructure (14) of the vehicle through the tilt mechansim (15) to the chassis (13) of the vehicle cannot cause a torque on the components of the tilt mechanism.
