Abstract: A dual path hydrostatic drive system having an electronic auxiliary drive auxiliary drive controller controlling the hydraulic output of left and right variable displacement pumps in response to the speed of the main drive wheels and a speed ratio signal from a speed ratio input control. In addition, the auxiliary drive auxiliary drive controller controls the outputs of the pumps within three basic boundary conditions; a hydraulic pressure boundary condition, a motor speed boundary condition and a power boundary condition. A clutch mode activation switch has two positions for signaling the auxiliary drive auxiliary drive controller to operate in a first mode in which the auxiliary drive system is shut down upon activation of the main clutch or a second mode where the auxiliary drive controller attempts to mirror the operation of the main drive wheels.

Abstract: An electrical control circuit for supplying an analog voltage signal to an electronic transmission controller for a hydrostatic transmission. The control circuit comprises two switches located on a T-bar handle of a control lever. The first switch is closed for reducing the speed of the vehicle and the second switch is closed for increasing the speed of the vehicle. The circuit is provided with a constant direct current voltage source. A first resistor is mounted in series with the voltage source. A second resistor in turn is mounted in series with the first resistor. The first switch is mounted in parallel with second resistor. A third resistor is mounted in series with the second resistor downstream from the first resistor. The third resistor is coupled to ground. The second switch is mounted in series with the second resistor downstream from the first resistor. A fourth resistor is mounted in series with the second switch. The second switch and fourth resistor are mounted in parallel to the third resistor.
