3.7 | Calibrating Cylinder Ratios

Cylinder Ratio Calibration compensates for differences in implement movement speeds between opposing control directions. Hydraulic systems rarely move at identical speeds in both directions. Differences in cylinder geometry, implement weight, hydraulic flow characteristics, machine design and gravity can all influence the speed at which the implement moves.

For elevation control, the implement may raise more slowly than it lowers due to implement weight and hydraulic loading.

For cross-slope control, left and right tilt movements may also occur at slightly different rates due to cylinder geometry and hydraulic system characteristics.

Cylinder Ratio Calibration measures the time taken to move the implement through its full range of motion in each direction and automatically calculates a correction ratio used by Automatic Control.
