ABSTRACT:
The invention relates to vegetation clearing devices and more particularly to a gravity roller means for use in vegetation clearing. The invention provides a vehicle for use in vegetation clearing which comprises a winch arrangement mounted on the vehicle and connected with, so as to drive, two independently controllable winch drums. Control lines are mounted around the winch drums and are connected by way of a fair lead arrangement to a roller. Roller mounting means are provided at the front of the vehicle, so that with the vehicle situated in position at the top of a slope or hill, the roller is allowed to roll down the slope clearing vegetation in its path.
