ABSTRACT:
A plow attachment for a roto-tiller wherein the roto-tiller includes a frame, a gear housing downwardly extending from the frame, means for driving a front axle shaft on each side of the gear housing, rear guide wheels, and means for driving said front wheels including a gear housing downwardly extending from the frame between said front wheels. The attachment includes a blade suspended from the forward end of a yoke which in turn includes a pair of parallel rearwardly extending members positioned so as to straddle the gear housing and a pair of front driving wheels. The yoke is pivotally mounted at the rear ends thereof to a pair of legs downwardly extending from the frame. A lift lever is pivotally mounted to the frame at an intermediate portion and connected at its forward end to the blade. The rear end of the lift lever is constantly urged upwardly by a spring and a combination adjustment and stop means is provided so as to positively position the lift lever and accordingly regulate the height at which the blade is disposed to the roto-tiller.
