The tractor is the centerpiece of technology in an agricultural operation. Some important functions of the tractor can only be realized hydraulically. The hydraulics play a significant role in fulfilling almost all essential functions. Often, the tractor has been a driving force behind new developments in mobile hydraulics. The book addresses the functional areas of work hydraulics, steering hydraulics, and drive hydraulics, along with the requirements present in these areas and the key components and systems used. Content: - Hydraulic functions on agricultural tractors - Systems for the work hydraulics of tractors - Gear pumps - Structure and function of axial piston machines - Directional and control valves - Electronic lift control - Steering systems of tractors and agricultural machinery - Hydrostatic drive systems - Hydropneumatic front axle suspension in tractors.
