This document discusses the basic principles and components of a hydraulic control system for a tractor. It explains that liquids are incompressible and transmit pressure equally in all directions, allowing hydraulic systems to greatly increase work force. The basic hydraulic system has a pump and cylinder. Additional components include a reservoir, check valve, relief valve, double-acting cylinder, hydraulic pump, cylinder, tank, control valve, safety valve, hoses, fittings, and lifting arms. Hydraulic pumps include gear pumps, rotary pumps, vane pumps, and axial and bent-axial piston pumps. Valves include control valves and relief valves. Hydraulic systems provide advantages like compact power and remote control but also have disadvantages like potential leaks and high

3. BASIC PRINCIPLES OF HYDRAULICS
1. LIQUIDS HAVE NO SHAPE OF THEIR OWN

4. 2. LIQUIDS ARE PRACTICALLY INCOMPREESSIBLE

5. 3. LIQUIDS TRANSMIT APPLIED PRESSURE IN ALL DIRECTIONS
LIQUIDS PROVIDE GREAT INCREASE IN WORK FORCE
