ABSTRACT:
A mowing system capable of being pulled behind a tractor or other prime mover utilizes a support apparatus for supporting a grass cutter adapted to cut grass as the cutter is rotated and moved forwardly into cutting relationship with grass. The support apparatus includes a wheeled frame for supporting the cutter for rotation and including a guard disposed on the forward side of the cutter. A pair of arm members are pivotally connected between the rear of the tractor and the wheeled frame to accommodate pivotal movement of the wheeled frame between an operative position at which the cutter is positioned for cutting grass disposed generally to one side of the tractor and a deflected position. A biasing mechanism, such as a spring, is connected between the tractor and the frame for biasing the frame from the deflected position toward the operative position so that when the frame is positioned in its operative position and moved by the tractor so that the guard is moved against an upstanding object, the frame can be pivoted by the object toward the deflected position in opposition to the force of the biasing mechanism to accommodate movement of the guard past the object and so that upon movement of the guard is moved past the object, the biasing mechanism returns the frame to its operative position.
