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

Pressure: Is the resistance to flow normally created by a load. This is expressed as Pounds per square inch or PSIFlow: This is the rate of which fluid flows through a system. This is expressed as Gallons per Minute or GPMDisplacement: This is the volume of fluid.

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.

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!
