<p>A battery-powered grass mower (12) is hitched to an electric garden tractor (10). The hitching system has arms (27) pivoted (29) to the tractor, which can be raised and lowered by means of an electric actuator strut (45). To hitch, the tractor is manoeuvred until pegs (30) pivoted on the arms are poised above sockets (20) on the mower; then, using the electric actuator, the arms are lowered, driving the pegs into the sockets. Once firmly engaged, a latch (36) engages and retains the pegs into the sockets. The latch is releasable electrically. All aspects of hitching and unhitching are under remote control from the driver's seat.</p> |
