Automatic wheel-slip control for tractors

Abstract

A 67 kW tractor was equipped with a control system to change either the draft-control set-point or the implement gage-wheel depth to keep wheel-slip within a preset range. Field tests with plowing and disk harrowing showed average fuel savings of 7.6% and average time savings of 4.9% per unit area tilled. The savings with disk harrowing were slightly greater, and those with plowing slightly less than these average figures.
