A wheeled work vehicle (1) comprises a forward chassis part (4) and a rearward chassis part (5) pivotally connected about a substantially vertically extending primary pivot axis (7) for steering thereof. A pair of forward ground engaging wheels (29) are carried on a forward suspension unit (32), and a pair of rearward ground engaging wheels (30) are carried on a rearward suspension unit (33). The forward suspension unit (32) is pivotally connected to the forward chassis part (4) by a pair of main forward transverse pivot shafts (63) pivotally coupled to the forward chassis part (4) by corresponding main forward pivot mountings (65). The main forward transverse pivot shafts (63) defines a main forward transverse pivot axis (59) about which the forward suspension unit (32) is pivotal relative to the forward chassis part (4). The forward suspension unit (32) comprises a pair of spaced apart trailing arms (35) which are joined by a torsion shaft (68) of tubular steel, which is rigidly connected to the trailing arms (35). The torsion shaft (68) defines a torsional axis (70), and permits limited upward and downward pivotal type torsional deflection of the trailing arms (35) relative to each other. The rearward suspension unit (33) is substantially similar to the forward suspension unit (32) and is coupled to the rearward chassis part (5) about a pair of main rearward transverse pivot shafts (87) in a similar manner as the forward suspension unit (32) is coupled to the forward chassis part (4).

A suspension unit for a wheeled work vehicle, the suspension unit comprising a pair of spaced apart wheel carrying arms for carrying respective ground engaging wheels, a main mounting means defining a main transverse pivot axis and configured for pivotally connecting the suspension unit to a chassis of a wheeled work vehicle with the main transverse pivot axis extending transversely of the direction of normal forward motion of the work vehicle and with the wheel carrying arms extending in one of a generally rearward direction and a generally forward direction from the main transverse pivot axis, and an elongated connecting member extending substantially parallel to the main transverse pivot axis between the wheel carrying arms and connecting the wheel carrying arms for retaining the wheel carrying arms in the spaced apart disposition, the connecting member being one of located relatively closely to the main transverse pivot axis, located adjacent the main transverse pivot axis and located substantially coinciding with the main transverse pivot axis.
