2 LINKAGE TO THE TRACTOR
The headstock is fitted with double linkage pins (category II). This
allows the mower to be attached to the tractor with more or less
offset (fig.3).
In most conditions, position c is recommended for coupling.
Always use position d when mowing down a descending slope so
that you can operate as far from the side as possible.
- Choose an attachment position so that the first mowing disc is
entirely offset from the track of the tractor tyre.
- Fit the lower arms to the linkage pins of the machine’s headstock.
- Fit the tractor top link to the machine.
- Connect the hydraulic hose for lifting the machine to a single-
acting hydraulic spool valve with floating position.
Permitted maximum oil pressure: 21.0 MPa (210 bar).
- Lift the headstock to such an extent that the hinge pin of the main
shaft (fig.4) is approximately 54 cm above the ground.
Check if the mower headstock remains level width-wise. If
necessary, adjust the tractor lever arms.
This adjustment of the tractor hydraulics is essential to
achieve optimum ground following of the mower.
- Place the parking jack in the raised position.
- Secure the tractor’s lower arms by means of stabilisation chains
or rods to eliminate any sideways movements.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO.
During first assembly or use of another tractor, check the
minimum and maximum overlap of the PTO shaft halves

- Fit the safety chain of the protection tube to a rigid part of the
tractor.
- Place the end of the control cord for locking the ram in the tractor
cab.
