ABSTRACT:
A grass cutting machine includes a grass cutter, a motor for driving the grass cutter, a housing for supporting the machine above ground datum, collector for collecting grass cut by cutter, and a fan for establishing a flow of air. The collector for cut grass further includes a duct for directing cut grass entrained in a stream of air from the fan. The duct has a collection mouth at an upstream end thereof and disposed in the region of the ground datum, thereof, and a downstream end of the duct connected to the collector. At least one air-outlet aperture is disposed in the region of the collection mouth, each aperture serving to direct at least a portion of the stream of air downstream from the collection mouth so as to draw into the mouth cut grass and to transport the cut grass through the duct to the collector.
