Abstract
A fullness detector for the grass collector of a lawnmower includes a pressure actuated switch which is responsive to a pressure condition in an air flow passage for conveying grass cuttings between the lawnmower and the collector. Preferably the condition is the static pressure within the passage, which is sensed in a sensing zone shielded by a baffle. The baffle serves to increase the difference in static pressure measured in the zone between any two conditions of fullness of the collector, and to reduce grass build-up in the zone. The signal for the detector may be used to control a function of the lawnmower.
