Abstract
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.
