HYDRAULIC SYSTEM
9. MIXED CONTROL
Mixed control is a system combining position control
with draft control.
When traction load increases, the draft control
functions to raise the lift arms (implement). When
traction load reduces, the lift arms (implement) lower to
the height set by the position control only, when traction
load increases, slippage or engine stop may occur
unless the implement is raised.
With the draft control only, plowing depth cannot be
kept constant if soil hardness changes greatly.
The mixed control serves to eliminate such
disadvantages.
