ABSTRACT:
An apparatus and method for slicing roofing material includes a prime mover in the form of a powered tractor, and a slicing assembly mounted to the rear end of the tractor. The slicing assembly includes a frame mounted to the tractor, a blade mounted to the frame, and a raising and lowering assembly for raising and lowering the rear end of the tractor, which in turn controls the position of the blade relative to the roof. The raising and lowering assembly includes a support member such as a wheel, and is pivotably mounted to the frame for movement between a raised position, providing penetration of the blade into the roofing material, and a lower position for maintaining the blade above the roofing material. A retainer mechanism is interconnected between the frame and the support assembly for selectively maintaining the support assembly in its lower position. A stop assembly is interconnected with the frame for controlling the angular position of the support assembly relative to the frame, to thereby control the amount of vertical movement of the support assembly relative to the rear end of the tractor and the amount of penetration of the blade into the roofing material.
