Abstract:
1. A sulky force equalizer comprising: two actuators, a left actuator attached to a left sulky shaft and a right actuator attached to a right sulky shaft; each actuator communicate via cross-connected fluid tubing; said sulky shafts comprising of a left carriage connected to a left side harness on the horse and the left actuator; the left carriage forming a resilient connection between the actuator body and the harness; capable of responding to forces of the horse and sulky; a right carriage connected to a right side harness of the horse and the right actuator; the right carriage forming a resilient connection between the actuator body and the harness; fluid pressure within the actuator chambers transfers between the left and right actuators via cross connected fluid tubing from a higher pressure chamber to a lower pressure chamber until the fluid pressure equalizes in the chambers; as fluid pressure equalizes, the sulky shafts and both actuator bodies maintain an even lateral position with the horse as the horse transitions throught his strides.
