Abstract: A suspension system for use with a work vehicle. The suspension system may include a suspension tower to which one or more shock absorbers may attach. The tower may permit the shock absorbers to attach at multiple locations, effectively allowing the angular orientation of the shock absorbers, and thus a suspension characteristic of the suspension system, to be altered. The tower may be movable relative to the vehicle, e.g., for crating/shipping.

Abstract: Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.
