MEANS OF INTERNAL HYDRAULIC CIRCUIT REGULATION

Hydraulic system enables three means of heave three-point linkage control.
Position regulation (fig.1) where some tools connected in three-point linkage are kept
automatically at constant height (position) to tractor.
circuit Mixed regulation (fig. 2) which is the combination of position and power regulation. It
is suitable mostly for tillage on lots with different soil resistance.
Power regulation (fig. 3), with which tools connected in three-point linkage are auto-
matically vertically adjustable depending on the change in soil resistance.
All means of regulation enable also work with tools which has supporting wheel in the
so-called free (floating) position.
