Amount Of Oil Taken From Outer Hydraulic Drives; Hydraulic Distributor Of The Outer Hydraulic Circuit - Zetor FORTERRA HSX 120 Operator's Manual

Amount of oil taken from outer hydraulic drives

If the amount of oil in transmission decreases after disconnecting the tool due to its permanent outflow out of
the tractor into the machine's hydraulic circuit, refill the oil missing.
If the amount taken exceeds the limit, hydraulic pump can absorb air and can get damaged.
For maximum amount of oil taken see the following table.
Type of work: On level ground
Max. oil consumption: 12 litres
Gearbox filling: standard
Type of work: On a slope
Max. oil consumption: 12 litres
Gearbox filling: transmission oil filling increased by 7 litres
Type of work: On level ground
Max. oil consumption: 27 litres
Gearbox filling: transmission oil filling increased by 15 litres,
maximum permissible oil quantity in the gearbox
Type of work: On a slope
Max. oil consumption: 20 litres
Gearbox filling: transmission oil filling increased by 15 litres,
maximum permissible oil quantity in the gearbox
Type of work: On level ground
Max. oil consumption: 8 litres
Gearbox filling: minimumpermissible oil quantity in the gearbox

Hydraulic distributor of the outer hydraulic circuit

The control levers of the outer hydraulic circuit are distinguished by colours. The lever colour corresponds to
the colour of quick coupler dusters that are controlled by the corresponding lever.
The outer circuit of the tractor hydraulics is controlled by the distributor with three four-position sections
controlled by levers.
The control levers of the sections are located in the cabin on the mudguard of the right rear wheel.
The numbers on the label of the control levers correspond to the numbers of the quick couplers.
The levers controlling both end sections are locked in the rear position at maximum oil flow rate into the
quick couplers 1 or 5. After overcoming the increased resistance the locked lever can be returned into the
position (N).
The quick couplers 1, 3 and 5 are equipped with the return valve - use for the connection of the working
branch of the machine with the increased requirement for tightness - minimum drop of the tools e.g. during
transport.
