What does SCV mean on a tractor?
Implements are the typical use of hydraulics off the tractor, and selective control valves (SCVs) control the volume of flow. Implements use hydraulic oil to perform a variety of functions such as raising and lowering parts as well as providing power to motors and other devices for mechanical movement.
What are hydraulics on a tractor?
The hydraulic system in a tractor works by the pumps transferring the fluid from the system’s reservoir all the way to the tractor’s hydraulic system. What this does is raise the level of energy of the fluid by increasing the pressure. The motor of the tractor then acts as the main power source for the pump.
What does hydraulic float mean?
A “Float” position is where the 2 work ports are connected together and also connected to tank. The pressure port usually is connected to the “out” or “power beyond ” port when in float position.

How do I know if my hydraulic valve is bad?
Many of the failures in a hydraulic system show similar symptoms: a gradual or sudden loss of high pressure, resulting in loss of power or loss of speed in the cylinders. The cylinder(s) may not move at all, or if they do they may move too slowly or may stall under light loads.
What are hydraulics uses?
Hydraulics are often used for moving parts of mechanical systems that need to lift or push heavy objects. The landing gear in an aircraft use several hydraulic cylinders to move the wheels into place and to cushion the aircraft’s landing.
What does a hydraulic multiplier do?
