ABSTRACT:
An industrial grade mower that has a cutting blade rotating in horizontal plane under an inverted dish like housing that has a cuttings discharge opening in a side wall of the housing, and a door moveably mounted on the housing selectively to cover and uncover the discharge opening respectively to mulch and discharge the cuttings. A multi link linkage system is mounted on the mower so the operator can controllably move the discharge door from one position to the other selectively to cover and uncover the discharge opening without interrupting the mowing operation. There is an actuator in proximity of the operator that is connected to a series of interconnected links and members with crank arms.
