(3) Mixed Control

[4] HYDRAULIC CYLINDER

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.
A: Position Controlled
B: Draft Controlled
C: Not Deep Even in Soft Soil
The external type hydraulic cylinders are used for
3-point linkage system. This hydraulic cylinder is single
acting type, and it is installed directly between hydraulic
lift arms.
The main components of the hydraulic cylinder are
shown in the figure.
