Mixed regulation of three-point linkage heave
Mixed regulation of three-point linkage heave is a means of regulation with which the tools connected in rear
three-point linkage is automatically vertically adjusted depending on the change in soil resistance, while it is
prevented for the depth to grow in soil cultivation with smaller soil resistance. The depth setting of soil
cultivation is done with a lever (1) as is the case with Power regulation of three-point linkage heave. Shift
lever (2) then in the direction of an arrow to the moment, when three-point linkage arms start lifting lightly.
Mixed regulation is set by this. Tools connected in rear three-point linkage can be lifted only by shifting the
lever (2) to (e) position at the end of a row. Tool is returned back to working position by shifting the lever (2)
to original setting.
External hydraulic circuit
Supplies pressure oil for hydraulic devices connected to
external outlet of hydraulics finished with quick-couplers.
Quick-coupler sockets with 12,5 mm clearance
correspond to international ISO recommendation.
Extrernal hydraulic circuit control elements
External hydraulic circuit control levers are placed on the
right fender.
Depending on tractor equipment the following
switchboards can be mounted to external hydraulic circuit.
A - Two-section switchboard
B - One-section switchboard
a - lever (a) controlling quick-couplers (1) and (2)
b - lever (b) controlling quick-couplers (3) and (4)
Quick-coupler (0) is directly connected with the area of
final house driving and is designed for returned oil from
external hydraulic devices (e.g. from rotation hydro
engines etc.).
