First Claim
Patent Images
1. A suspension system for carrying a cab, the suspension system comprising:
- a chassis assembly comprising a first chassis section and a second chassis section;
a linkage assembly comprising a first fore-aft linkage and a second fore-aft linkage for restraining movement of the first or second chassis sections, both the first and second fore-aft linkages coupled at a first end to the first chassis section and at a second end to the second chassis section; and
a lateral linkage for restraining rotational movement of the first or second chassis sections, the lateral linkage coupled laterally along the second chassis section.

Abstract
An agricultural vehicle is described having a chassis and a cab mounted on the chassis. A suspension system for reducing the accelerations transmitted from the vehicles tires or tracks through the frame, into the cab, and ultimately through to the operator is provided. By reducing the accelerations, the ride quality is greatly improved, allowing operators to operate a vehicle for longer periods of time without excessive fatigue.
