Abstract
A sulky force equalizer comprised of two actuators, connected together, and each actuator is connected to a sulky shaft. The two actuators work together in a pressurized feedback loop that captures and uses errant sulky-and-horse forces to counterbalance any imbalance of pulling forces from the horse; reduces the effort required by a horse to control, stabilize and pull the sulky; and correct any imbalance of the sulky shaft positions. The sulky force equalizer also operates in force analysis mode to test forces in the actuators.
