Hydraulic lift is a lifting system located at the rear of tractor. It consists of a housing mounted on differential case, lifting arms, main shaft, crank arm, connecting rod, cylinder, piston and control valve. Implement is mounted on hydraulic lift arms by using three-point linkage. By using control levers, the implement is kept in the desired position or lowered.
When the operator moves the lever, the movement is transferred to control valve and the valve sends the oil to the cylinder to rise the lift arms.
Hydraulic lift automatically keeps tractor effort constant level by adjusting implement working depth.
This control type ensures more constant working depth and less tractor effort.
Autolift system raises and lowers the implement without any change on the control lever position.
