A frame system for a vehicle including a high-voltage component that includes a pair of spaced apart primary rails that extend from a front of the vehicle toward a rear of the vehicle and a pair of longitudinally extending sills. An impact support rail extends outward from each of the primary rails, and connects each respective primary rail to one of the sills. A cross-member extends outward from each of the primary rails, and connects each respective primary rail to one of the sills, and a laterally extending frame support member extends between the sills at a location between the impact support rails and the cross-members. A pocket is collectively formed between each primary rail, the respective impact support rail, the respective sill, the respective cross-member, and the laterally extending frame support member, and the pocket is configured for receipt and protection of the high-voltage component.

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.
