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.
The engines in our beloved garden tractors have enough power to push hydraulic oil to 2,000 psi or more. By pushing this oil into different sized hydraulic cylinders we can build almost any tool imaginable.
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.
Digital Multi-Meters come in two common varieties: Auto- Ranging, and Non Auto-Ranging. A non auto-ranging meter requires you to select a range of “sensitivity” for the given function you are using. For example if you want to measure resistance, you would need to select a range of up to 200 ohms, up to 20Kohms (20,000 ohms), 200Kohms, etc. An auto-ranging meter will automatically figure out the range and give you a measurement.
