Automatic wheel-slip control for tractors

, : Automatic wheel-slip control for tractors. Proceedings, 57th annual University of California farm machinery conference, held in Davis, California, USA, 19 January 1988: 36-41

A 90 hp 2 WD tractor was equipped with a doppler radar unit to monitor forward speed and a magnetic pick-up was mounted on the right rear axle. Signals from both instruments were compared by a data-logger to determine wheel slip. The system performed satisfactorily in field tests using a 3-furrow mounted plough with 16 inch furrows and a trailed 9 ft offset disc harrow with a hydraulically actuated wheel lift system, giving easier tractor operation and more uniform cultivation.
