Abstract
A lawn mower having a chute disposed within a hopper for receiving clippings from a cutter assembly and a motor for oscillating the chute to distribute the clippings. A sensor is connected to the motor energizing circuit for measuring the current flowing to the motor as a measurement of the resistance to chute oscillation resulting from the accumulation of clippings. The sensor is operative to actuate an alarm and disable a clutch which couples the mower's engine to its cutter assembly when the motor energizing current reaches a predetermined level.
