Chapter 7 Tractor's PTO System Section 3 Hydraulic Lift Hitch The devices using hydraulic to lift and control the farm machinery is called the hydraulic lift hitch.Its functions are as follows:connecting and towing the farm machinery,manipulating the upward and downward of farm machinery,controlling the tilth or hoisting height of the farm machinery,gaining weight to the driving wheels to improve the adhesion property and transmitting the hydraulic energy to the operating machinery for other operations. Hydraulic lift hitch is composed by the hydraulic system,control mechanism and suspension gear. 械电子工程学 Automobile and Tractor Northwest A&F University
