Snow thrower including reverse shut-off mechanism

摘要

A snow thrower having a reverse shut-off mechanism configured to deactivate voltage supplied from a power source to a motor that rotates an auger assembly. The reverse shut-off mechanism deactivates the voltage supplied in response to the snow thrower being moved or rolled in a reverse direction. Upon movement of the snow thrower in a forwards direction to clear snow or other debris, the shut-off mechanism reactivates voltage supplied from the power source to the motor that rotates the auger assembly. This allows the snow thrower to conserve power and/or fuel when the snow thrower is not being used to clear snow or other debris.

主权项

1. A snow thrower, comprising:
a frame; a main housing coupled to the frame and having an inlet cavity; an auger assembly disposed in the main housing and extending across the inlet cavity; a motor disposed in the main housing and coupled to the auger assembly, the motor adapted to rotate the auger assembly; a wheel assembly coupled to the frame and including an axle and wheels coupled to ends of the axle for rolling the snow thrower; a shut-off mechanism coupled to the wheel assembly and adapted to:
count a number of rotations of the wheels in a reverse direction, anddeactivate power to the motor in response to the number of rotations meeting or exceeding a threshold number of rotations.
