Think of voltage as electrical pressure; amperage as the volume of electricity flowing; and resistance as electrical friction that resists current. Direct Current or DC is electricity flowing from a battery. Alternating Current is electricity flowing from an alternating power source such as a stator.
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.
