The basic components in a hydraulic system are:1.) Reservoir 2.) Pump 3.) Valve 4.) Piston or Motor
Most of the circuits in lawn and garden tractors use low amperage with the exception of the starting circuit. The wiring also only runs a short distance. I recommend using 6 AWG wire for the high amp starting circuit, and the negative side of the battery to common ground connection. All other wires can be 16 or 14 AWG. The easiest and most effective way to make all of the connections is by using nylon wire crimp connectors. Nylon wire crimp connectors are more durable than ones made from PVC. They are also easier to install than soldered connections. The most common crimp connectors you will use are spade and ring connectors.
Do you want to turn your old garden tractor into a serious earth moving machine? How about convert your manual lift system into a power system? Want to add a rear PTO? Do you want to multiply your engine’s power by 1,000 times or more? It’s all possible by using the science behind hydraulic power!
This article serves as a basic introduction to what is possible with hydraulics for your garden tractor. There are a wide variety of pumps, valves, motors, hoses, etc. I hope this article inspires you to research more of what you can do with the physics of fluid.
