Title: Wheel slippage monitor

Abstract: In plowing or towing of other vehicles or implements with a tractor it generally is desirable to move as fast as is economically feasible. Attempting too high a speed may be self-defeating through wheel slippage of the pulling tractor which may reduce efficiency to an uneconomic level. In accordance with the present invention an electronic signal is provided corresponding to the speed of the driving wheels of a tractor, and another electronic signal is provided corresponding to the ground speed of the tractor. These signals are compared electronically, and a visual readout is provided for the operator of the tractor so that he may know if he is operating within acceptable conditions of efficiency. Both audio and visual warning signals are provided to the tractor driver if slippage exceeds a predetermined maximum, corresponding to a predetermined minimum allowable efficiency.
