ABSTRACT:
A tractor has a protective cab mounted thereon by means of a plurality of mounting structures. Each mounting structure includes a member extending from the cab and an associated member extending from the tractor, allowing a degree of movement of one member in all directions to an extent relative to the other. Movement of one member relative to the other in any direction results in compression of a resilient member associated with the extended members. Movement of one extended member relative to the other in at least one particular direction is resisted by the resilient member at a given spring rate for a certain extent of travel, and additional travel in that direction is resisted by another, greater, spring rate.
