A vehicle with a hydrostatic drive circuit assembly including a vehicle frame and a hydrostatic drive circuit. The hydrostatic drive circuit has four hydrostatic motors configured to produce a torque and cause rotation of the wheels or tracks of the vehicle, and two hydrostatic pumps adapted to distribute fluid to the hydrostatic motors. A controller is provided to signal for adjustments of torque applied to the wheels when a first wheel is rotating at a first rate and a second wheel is rotating at a second rate different than the first rate. The controller is adapted to cause adjustments to the displacement in either the motors or the pumps, and cause a change in torque in the first wheel that is substantially equal and opposite to the change in torque in the second wheel.

[ What is claimed is:] [1.]1. A hydrostatic drive circuit assembly for use in a vehicle, the hydrostatic drive circuit assembly comprising:a first hydrostatic motor configured to produce a torque and cause a rotation of a first member associated with the first hydrostatic motor;a second hydrostatic motor configured to produce a torque and cause a rotation of a second member associated with the second hydrostatic motor;a first hydrostatic pump configured to distribute fluid to the first and second hydrostatic motors; anda controller configured to adjust a torque in the first and second members when the first member is rotating at a rate faster than a rate at which the second member is rotating, wherein the controller adjusts the torques by decreasing a displacement in the first hydrostatic motor and increasing a displacement in the second hydrostatic motor.
