Abstract
A rear castor wheel for a tractor includes a beam carried on a fork which connects to a castor mounting assembly attached to a rear pivotal beam of the tractor. A suspension system connects the fork to the mounting assembly to provide suspension movement and includes a first transverse plate assembly attached to the mounting assembly intersected by a second plate assembly attached across the two sides of the fork. The plates are connected by a single elastomeric block located on a first side of the axis remote from the beam and two elastomeric blocks located between the first and second plate assemblies on a side of the axis closer to the beam so that upward movement of the beam causes compression of the first and second elastomeric blocks which are shaped such that the internal strain of the block as the beam moves upwardly is substantially uniform through the block.
