Abstract:
A device for removing debris from a drive wheel of a vehicle propelled by a continuous loop ground-engaging track, said drive wheel having an outer peripheral surface, rotatably mounted to a body of a vehicle, comprising:an elongated mounting arm having first and second ends;said first end of said mounting arm being rigidly fixed to the vehicle body inwardly of and adjacent to the drive wheel thereof;an auxiliary wheel rotatably mounted on said mounting arm so as to be positioned adjacent the outer peripheral surface of the drive wheel, said auxiliary wheel having a substantially circumferential surface for frictionally engaging the outer peripheral surface of the drive wheel and thereby being rotated by the drive wheel in a second direction opposite a first direction in which the drive wheel rotates;said engagement of the auxiliary wheel with the drive wheel causing debris on the drive wheel to be dislodged from the drive wheel;said auxiliary wheel having a resiliently deformable outer circumference for resilient frictional engagement with the drive wheel.
