Abstract
A suspension system for a cab of an agricultural vehicle having a frame. The suspension system includes a pair of first mounts configured for connecting the cab to the frame at a first region, a pair of second mounts configured for connecting the cab to the frame at a second region, and a pair of actuators configured for connecting the cab to the frame at a third region. The actuators are configured for variably damping a movement of the cab. The suspension system also includes a first suspension linkage laterally connected in between the second mounts. The suspension system also includes a second suspension linkage configured for connecting the cab to the frame at a fourth region. The second suspension linkage is configured for limiting a rotation of the cab about the longitudinal axis of the frame.
