AGGREGATION TO A TRACTOR
The machine can be connected only to a tractor, whose curb weight is identical or higher than the overall
weight of the connected machine.
The machine operator must observe all generally valid regulations of work safety, health protection, fire
safety, and environmental protection.
The operator may connect the machine exclusively to a tractor that is equipped with a rear three-point
suspension and a functional undamaged hydraulic system.
Tabl.4 – The table of requirements for the towing means for work with the machine:

Requirement for the tractor's hydraulic
system
(10)
Side frame folding circuit
(14)
Circuit pressure 200 bar,
2 pcs of quick-coupler
sockets ISO 12,5
(11)
Axle lifting circuit
(15)
Circuit pressure 200 bar,
2 pcs of quick-coupler
sockets ISO 12,5
Rollers lifting circuit
(15)
Circuit pressure 200 bar,
2 pcs of quick-coupler
sockets ISO 12,5
Connect the machine using the TPS suspension bar to the lower arms of the rear TPS of the tractor, secure
the TPS arms using pins against disconnecting.
When connecting, no persons may stay in the space between the tractor and the
machine.
3.2.
HYDRAULICS CONNECTION
Connect the hydraulics only when the hydraulic circuits of the machine and the tractor (aggregate) are in a
pressure-less condition.
The hydraulic system is under high pressure. Regularly check for leaks and immediately remove obvious
damage of all lines, hoses, and pipe unions.
When seeking and removing leaks, use only the suitable tools.
For connecting the hydraulic system of the machine to the tractor, use the plug (on the machine) and the
socket (on the tractor) of the quick-couplers of the same type. Connect the machine quick-coupling units
to the tractor hydraulic circuits in such manner that the
RED DUST CAPS
side frame folding are on one
control circuit, the
YELLOW DUST CAPS
roller machine lifting on the second control unit and the
GREEN DUST CAPS
axle machine lifting on the third control circuit.
Fig. 4 – Hydraulic Circuits
RED DUST CAPS
– control of side frames folding
1 TAPE
– folding side frames into the transport position
2 TAPES –
unfolding side frames into the work position
YELLOW DUST CAPS
- control of the rollers
1 TAPE
– drawing out roller piston-rods => shallowing the
machine
2 TAPES
– drawing in roller piston-rods => recess of the machine
GREEN DUST CAPS
– control of the axle
1 TAPE
– drawing in axle piston-rods => Machine positioning
2 TAPES
– drawing out axle piston-rods => Machine lifting
In order to prevent accidental or foreign person
(children, passengers) caused movement of the
hydraulics, the control switchboards on the tractor must
be secured or blocked in the transport position.
