Hayter H Series User Manual

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 3mm.
Check this by placing the
tractor on a hard level surface
and measuring the clearance
heights front 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 inflated evenly
all round - if not, inflate to the
correct pressures.
2/Are the cutter deck Hanger
Brackets (fig 39A) 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 grease. (See
page 30 fig 56)
3/ Is the front axle pivoting
freely - if not, clean and oil.
4/ Is there any impact damage
that has bent or distorted the
deck or suspension brackets.
(A matter for your dealer)
(f the deck is still uneven:-
LEVELLING FRONT TO
BACK
(you need two people for this
operation - one to lift the deck
while the other removes or
relocates the Trunnion)
1/ Ensure that the Anti Scalp
Wheels are all adjusted in the
same hole - if not, rectify.
2/ Lower the cutter deck to a
position one above the lowest
setting - check levels with ruler
or tape.
3/ Now locate the front to back
Adjustment Rod to the right
(offside) of the cutter. At the
rear end of this rod, near the
rear offside wheel, you will find
the Trunnion (fig 39B) 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’ shorten or lengthen the
rod.
4/ To free the Trunnion use a
9/16” spanner or socket to
remove the 3/8” Nyloc nut and
washer and push it free.
5/ Rotate the Trunnion to
advance it up the rod to lift the
back of the deck. Rotate it the
other way to lift the front.
Adjustment is rapid so try one
or two turns and relocate the
Trunnion bracket and secure -
then check the effect. Repeat
and re-check if necessary.
