Hydraulic connections
To use the machine with a tractor with a hydraulic output
in excess of 60 L/min (15.9 gal/min), a flow divider must
be fitted to prevent the circuit overheating.
Machine without a hydraulic system
In order to power the machine's independent distributor,
the machine can be connected to the tractor hydraulics
in one of three ways:
1. Connection to a single-acting control valve and
direct return to the tank.
2. Connection to a double-acting distributor. The first
port is used to connect the pressure hose and the
second for the return hose. On fitting, make sure
that the direction of the oil flow is correct..
3. Connection to a line from the tractor.
- For maximum user-friendliness, the original hydraulic
distributor on the tractor must be equipped with a
continuous pumping position.
- The operating pressure of the hydraulic circuit is
190 bar (2755.8 psi).
- The minimum and maximum hydraulic oil flow for a
standard machine is 30 l/min (7.9 gal/min) and
60 l/min (15.9 gal/min) respectively.
- The pressure and return hoses are fitted with a male
push/pull coupler (ISO 7241).
- The pressure hose has a white arrow on a red
background (1), pointing from the tractor to the
machine.
- The return hose (2) is marked by a white arrow on a
blue background, pointing from the distributor towards
the tractor.
If your tractor is fitted with a closed-center
hydraulic circuit, make a return to the filter.
