PARKING BRAKE SYSTEM FOR A LAP BAR CONTROLLED ZERO TURN RADIUS MOWER

摘要

The parking brake system for a lap bar controlled lawn maintenance vehicle includes at least an actuation assembly and a stop assembly. The actuation assembly includes a push arm and a rotatable pedal arm, and the push arm is attached to a lap bar and is rotatable between and engaged position and a disengaged position. Rotation of the push arm from the disengaged position to the engaged position causes rotation of the pedal arm, and such rotation of the pedal arm causes the stop assembly to prevent the axle for the rear wheel that is controlled by the corresponding lap bar from rotating.

1. A parking brake system for a lawn maintenance vehicle, the lawn maintenance vehicle including a pair of opposing lap bars for independently controlling movement of a pair of rear wheels, said parking brake system comprising:
an actuation assembly attached to one of said lap bars, said actuation assembly includes a rotatable push arm and a rotatable pedal arm, said push arm is spaced apart from said pedal arm when said push arm is in a disengaged position and said push arm is in contact with said pedal arm when said push arm is in an engaged position; a stop assembly operatively connected to said actuation assembly, said stop assembly including a rotatable pawl selectively engageable with a parking gear, said parking gear operatively connected to an axle to which one of said rear wheels is attached for selectively stopping rotation of said axle; and wherein rotation of said push arm from said disengaged position to said engaged position causes said push arm to contact said pedal arm, wherein said pedal arm is rotated in response to said contact with said push arm and such rotation of said pedal arm causes said pawl of said stop assembly to engage said parking gear which prevents rotation of said axle.
