Cutter fails to start or cuts out when
switched on
CHECK:
1. Are you on the tractor? – Unless you sit on
the seat, the safety switch cuts out the Cutter
Deck.
2. The correct function is selected on the
dashboard.
3. That either the cutter switch or the safety
switch on the seat is not faulty – if so, call
your dealer.
4. Is the battery low? – The clutch engage switch
will only operate if the battery is well charged.
5. The engine is running.
Uneven cutting
CHECK:
1. That all tyres are inflated to their correct
pressures – see Specification pages
2. That the front axle is pivoting freely.
3. The deck brackets are moving freely and not
locking up.
4. That the deck is level from side to side and
back to front (See cutter deck levelling).
5. That one or more of the cutter blades are not
worn or damaged – if this is the case, it is
necessary to call your tractor dealer.
Uneven cut (cuts shorter one side than
the other)
CHECK
:
1. That the tyres are all inflated to the correct
pressures (see above).
2. That the front axle is pivoting freely.
3. That the deck brackets are moving freely and
not hitching up.
4. That the side deck level adjustment is correct.
Cut is uneven or untidy in one or more
sectors
CHECK:
1. That the cutter deck is levelled correctly front
to back.
2. That one or more of the blades are not worn
or damaged – if so, call your dealer.
Troubleshooting (Cutting)
Page 43
The cutter seems to lose power and the
belt slips and overheats
CHECK:
1. That the cutter belt tension is correct.
2. That the cutter deck is not clogged with wet
cuttings.
3. That the cutter drive belt is not worn.
We do not recommend that customers attempt to
change cutting blades themselves: remember that
it is never worthwhile to have blades re-ground. It is
cheaper and better to replace blades – re-grinding
is likely to affect the hardening of the blade and its
balance.
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. Check
this by placing the tractor on a hard level surface
and measuring the clearance heights front to back
and side to side with a steel ruler or tape, with
the cutter set one adjustment up from its lowest
position.
If the cutter deck seems to require
levelling, first check these other possible
causes:
1. Are the tyres correctly inflated? – If not, rectify
using the figures in the specification section.
2. Are the cutter deck hanger brackets moving
freely or are they hitching up. To check this,
lift the cutter deck to its highest position
and lift and rock it, watching to ensure that
the brackets move freely – if not, clean and
lubricate.
3. Is the front axle pivoting freely? – If not, it may
require lubrication or adjustment.
4. Is there any impact damage that has bent or
distorted the deck or suspension brackets (a
matter for your dealer)?
