ABSTRACT:
A collapsible discharge deflecting chute (often called in the industry today a "chute deflector") for rotary mowers hingeably and collapsibly attached to the mower housing comprising a front vertical panel, a front hinge plate hingeably connected to the front vertical panel for removably securing the front vertical panel to the mower housing, an outer top panel hingeably connected to the front vertical panel, an inner top panel hingeably connected to the outer top panel, a top hinge plate hingeably connected to the inner top panel for removably securing the front vertical panel to the mower housing, and a rear flap panel hingeably connected to the inner top panel. The collapsible discharge deflecting chute has "memory" in that it is biased in an open position by gravitational forces (on metal version, by "molded" memory if plastic) during normal operating conditions permitting the discharge of grass clippings from the mower housing. The collapsible discharge deflecting chute collapses upon striking an object, blocking the mower housing outlet discharge deflecting chute; however, the collapsible discharge deflecting chute automatically springs into the open position upon removal of the object.
