3.1.
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 (or bottom fixed suspension) and a functional undamaged hydraulic system.

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, or connect the machine to the fixed bottom suspension and
secure it against disconnecting.
If the drawbar of the machine is equipped with a safety chain, attach it to the tractor.
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 quick-couplers of the machine to the hydraulic circuits of the tractor so that the
RED DUST
CAPS
for
folding side frames is on one control circuit, the
YELLOW DUST CAPS
for lifting the
machine on rollers (or rollers and drawbar) is on the second control circuit and the
GREEN DUST CAPS
for lifting the machine on the axle is on the third control circuit.
