This same principle can be applied if you wanted to build a rear fork lift, 3-point hitch, snow blade set up. Anything! Instead of using a hydraulic cylinder you can use a hydraulic motor and add a PTO shaft to power implements at any location you desire. You can also vary the motor speed by controlling the volume of oil that feeds it. All you need are the 4 basic hydraulic components of reservoir, pump, valve, and device.
A hydraulic system is a simple, space efficient way of multiplying and transferring your engine’s power to multiple applications for your tractor. By utilizing hydraulics you can build a front end loader, backhoe, 3 point hitch, 3 way plow, a dump trailer and much more. The limits are in your imagination.
