CONNECTING MACHINES AND TOOLS TO EXTERNAL HYDRAULIC CIRCUIT

Connecting double-acting roller
Connect double-acting roller always to quick-couplers of one section.

Connecting machines and tools assembled from more parts

When working with agricultural machines which are assembled from more parts (combiners, shears, harrows), in which side
frames are jointly connected to a central frame, tilted to vertical position by separate hydraulic rollers in transport, controlled by
tractor external hydraulic circuit, it is advisable to connect lifting branches of rollers to quick-couplers (2) or (4), which are
equipped with a reverse valve.
Connecting rotation hydro engine
If there is a rotation hydro engine connected to external hydraulic outlet, it is necessary to connect its reverse branch, always to a
quick-coupler (0).
Connecting reversing rotation hydro engine
Reversing rotation hydro engine must be for function connected to quick-couplers of one section. When connecting hydro en-
gines, securing valves need to be included in both branches, which reliably restrict pressure peaks with machine run-out. Waste
from these valves is connected to a quick-coupler (0).
Auxiliary machines using oil filling of external hydraulic circuit must be filled with the same kind of oil, which is
recommended for gear system of the tractor!
Quick-couplers sockets of an auxiliary machine need to be properly cleaned before connecting.
