Low Profile Heavy-Duty GrassFlap with SEL Pedal. The GrassFlap is the ideal OCDC, operator controlled discharge chute. The foot-operation allows the user to close the discharge chute at any time, any place without taking their hands off the mower’s controls. The chute blocker plate opens a full 180 degrees and completely clears the edge of the mower to allow the mower to fit in those tight spaces. The GrassFlap fits most zero-turn mowers.
