US Patent 7726110 Discharge chute for turf mower

A discharge chute assembly for a turf mower having a resilient deflector and a frame connecting the deflector to a mower deck proximate to a side discharge outlet. The frame includes one or more extension elements which engage the deflector. In one embodiment the extension elements are captured within pockets defined within the deflector. The pivoting frame mass facilitates a quick recovery to a guarded condition after the deflector rises in contact with an obstruction. Additionally, the frame mass allows the deflector to maintain an upright, unguarded orientation without additional biasing forces which is useful, for example, during a machine loading operation.
