The basic components in a hydraulic system are:1.) Reservoir 2.) Pump 3.) Valve 4.) Piston or Motor
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!
Think of this as electrical volume. Amps can be determined by taking your voltage (12 volts) and dividing it by the resistance of a load. This is illustrated with the following formula: A = V/R
Measuring voltage is one of the most common tests a tractor mechanic will conduct as he troubleshoots a system. The presence of the correct voltage will determine if a component is functioning correctly or not. A common voltage test will be of the battery. A healthy battery should read about 12.5 volts, and a battery that is being charged should measure between 13 and 14.5 volts.
