– Connect the hydraulic pipes to the tractor's two
way circulation system.
– Pay attention to clean and dry clamp.
Dirt may cause untightness and damage.
– The minimum required operating
pressure of the tractor is 60 bar and
the maximum permitted is 120 bar.
2.5 Hydraulic relief connection
To adjust the cutting bar to an uneven surface during
mowing, the force of the cutting bar onto the surface
must be reduced to 120-140 kg.
If your tractor has no hydraulic relief of the tractor
arms, you need to install the springs for mechanical
relief (see chapter: Special versions – optional
equipment).
– Nobody is allowed to stay between
tractor and machine when lifting or
lowering the hydraulics.
Hydraulic relief:
– Place the machine in the working position.
– Engage the floating position of the tractor
arms.
– Set the relief pressure to provide 120-140 kg
relief of the cutter bar onto the surface.
– The machine is ready for operation.
