초록 ▼

A ride-on, self-propelled vehicle having front caster wheels, such as a zero-turn mower, includes a front brake system. The actuating power for the front brake pass through a spindle supporting the front caster wheel. In a preferred embodiment, a center shaft of each spindle or a concentric outer ring of a sleeve of each spindle passes a force from a brake actuator to a brake for the respective caster wheel. Actuation of the brake actuator moves a member into frictional contact with a portion of the front wheel or an object attached to the front wheel to applying a braking force.

대표청구항 ▼

1. A mower comprising: a frame;a rider's platform attached to said frame;a mowing deck attached to said frame, said mowing deck including blades;first and second rear wheels attached to said frame;an engine attached to said frame, said engine having an ability to rotate said rear wheels to impart movement to said mower and having an ability to rotate said blades for cutting grass;a front caster wheel attached to said frame;a brake attached to said front caster wheel; anda brake actuator attached to said frame, wherein said brake actuator controls operation of said brake, wherein said brake actuator communicates with said brake via a path which passes through a spindle supporting said front caster wheel, and wherein said brake includes friction applying components to slow or stop rotation of said front caster wheel upon operation of said brake. 2. The mower according to claim 1, wherein said front caster wheel is a first front caster wheel, said spindle is a first spindle, and said brake is a first brake, and further comprising: a second front caster wheel attached to said frame; anda second brake attached to said second front caster wheel, wherein said brake actuator also controls operation of said second brake, wherein said brake actuator communicates with said second brake via a path which passes through a second spindle supporting said second front caster wheel, and wherein said second brake includes friction applying components to slow or stop rotation of said second front caster wheel upon operation of said second brake. 3. The mower according to claim 1, wherein said front caster wheel is the only caster wheel attached to said mower. 4. The mower according to claim 1, wherein said front caster wheel resides generally centered in front of said mowing deck.
