An electronic traction control system for a vehicle having multiple
hydraulic driven wheels includes a plurality of digital displacement
pumps, a plurality of drive systems having counterbalance valves and
motors used to drive wheels, and electronic flow control valves used in
association with each drive assembly. Additionally the system has a
steering mechanism that is electrically connected to a digital sensor and
a proportional sensor that sends signals to a system controller that
operates the functioning of the digital displacement hydraulic pumps.
