ABSTRACT:
A grass catcher for receiving air and grass clippings from a mower cutter deck includes an inlet for admitting air and clippings into the grass catcher, an outlet port for exhausting air out of the grass catcher, and at least two cylindrical, perforate air filters interposed between the inlet and the outlet port. The filters separate grass clippings from the air and permit air to pass through the filters and on to the outlet port. The grass catcher also includes a wave form energy transmitter and a wave form energy receiver positioned in the grass catcher. The transmission of wave form energy between the transmitter and the receiver is interrupted when the level of accumulated grass clippings in the catcher exceeds a predetermined level. The interruption of the transmission triggers an alarm to alert an operator of the mower of the high clipping level within the catcher.
