Abstract
A tractor has a hydrostatic steering assembly 16 including a steering column 22 connected to a steering valve 18 mounted on a housing 10 for a dash. To dampen vibrations of the steering column 22, and to prevent any excessive movement of it when a high load is applied, a support assembly 26 is provided. This comprises a support column 28 with a bracket 30, at its upper end, which has an aperture 42 through which the steering column 22 passes. On the underside of the bracket 30, there is a polyurethane vibration dampening insert 32 which has an aperture 46 through which the steering column 22 also passes. The latter aperture 46 fits around the steering column 22 closely while the bracket aperture 42 is larger. Due to the difference in the sizes of the apertures 46, 42, slight deflections of the steering column 22 will be opposed only by the insert 32, but if a high load produces a large enough deflection, the insert 32 will be so compressed that the steering column 22 will come into abutment with the bracket 30 to limit its movement.
