1. Return coupling (T2), male quick coupling 1” (25 mm)
2. Pressure coupling, female quick coupling 3/4” (20 mm)
3. LS coupling, female quick coupling 3/8” (10 mm)
4. Free return coupling (T1), male quick coupling 1” (25 mm)
5. Case drain coupling (T0), female quick coupling 1/2” (12.5 mm)
IMPORTANT: Use only couplings that comply with the standards.
1. Connect the tank hoses.
IMPORTANT: Always connect the tank hoses first and take them away last in
order to avoid damages in the hydraulics.
Always prefer the free return coupling T1 as the primary tank port. Use return
port T2 only if two return ports are needed; the counterpressure in the return
port T2 is 8 bars higher at 150 l/min than in the free return port T1. The case
drain coupling T0 does not have any counterpressure and can only be used
as case drain line.
2. Connect the LS line hose connector of the implement to the LS line.
The pump pressure settles to a level determined by the LS pressure of the
implement. The pressure in the tractor is determined by the device that has
the highest LS pressure.
If the implement (and any other device) is not used, the pump line has only
standby pressure caused by the pump controller (normally 20…25 bar). This
improves fuel economy and decreases oil temperature since there is flow
only when the implement requires it.
