Troubleshooting (Cutter Levelling)
The Cutter Deck should be set so that it is parallel
to the surface it is cutting with a maximum variation
from side to side or front to back of 3 mm.
Levelling front to back
Check tyre pressure is correct first. If not inflate tyres.
You need two people to level the deck – one to lift
the Deck while the other removes or relocates the
adjuster Trunnion.
1. Ensure that the Anti-Scalp Wheels are all set to
the same height – if not, rectify (Fig. 41).
2. Lower the Cutter Deck to a position one above
the lowest setting – check levels with a ruler
or tape.
3. Now locate the Front to Back Adjustment Rod
to the right rear offside wheel, you will find
the Trunnion (Fig. 42) that links the rod to
the Deck Hanger Bracket. Both the Trunnion
and the Rod are threaded and adjustment is
achieved by rotating the Trunnion to ‘in-effect’
lengthen the Rod.
4. To free the Trunnion, use a 17 mm spanner or
socket to remove the M10 Nyloc nut and
washer and push it free.
5. Rotate the Trunnion to advance it up the Rod
to pivot the back of the Deck. Rotate it the
other way to lift the front. Adjustment is rapid,
so try one or two turns first and relocate the
Trunnion and secure – then check the effect.
Repeat and re-check if necessary.
For best results, set the Anti-Scalp Wheels in the middle adjustment holes. If
you are experiencing scalping, this can be minimised by setting the wheels in
the lowest adjustment holes.
