With "Texas Hydraulic Horse Walkers" there are no belts to burn out.  With the patented design of our hydraulic system, there are no pulleys, gearboxes or bearings to maintain.  Our walkers consist of heavy duty construction of an 8 5/8" upright pipe, which also serves as the oil tank reservoir, that is braced with 2" channel iron and has a sight glass to check the 32 wt. hydraulic oil required for operation.  The carousel is also made from 8 5/8" pipe.  Both the 4 arm and 6 arm walkers have high speed roller chains. The arms are made from 3" sq. tubing with quick releases for the safety of your horse). Each walker is equipped with variable speed of forward and reverse. It has 0-5 rpm that comes with a thermally protected 2hp-110 or 220v motor.  It also includes a heavy duty base of 1 1/2" pipe and channel iron.   Mounting posts are furnished...all you need to mount your walker are four post holes dug, approximately two sacks of Sacrete per hole, and an eight or ten gauge electrical wire run to the center of the walker.
