A lawn care device including a mobile support apparatus, a grass cutting mechanism coupled to the mobile support apparatus and a lawn striping device coupled to the mobile support apparatus. The lawn striping device has a grass contacting member and at least one torsional restraining device coupled to the mobile support apparatus. The torsional restraining device is coupled to the grass contacting member. The torsional restraining device allowing a restrained pivoting of the grass contacting member relative to the mobile support apparatus.

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.
