ABSTRACT:
A walk behind tractor with a power take-off is combined with a blade assembly support assembly and lift assembly. The blade assembly allows a blade to be set at an adjustable angle. The support assembly supports added weight for increasing the force on the blade. Rollers are provided at points of contact between the support assembly and blade assembly to allow movable points of contact. A rolling movement accommodates the downward force of applied weight without tearing at the blade assembly along a transverse direction during oscillation. The lift assembly raises the tractor front end moving the blade out of contact with the floor and floor covering.
