REPLACING AND
TENSIONING
PTO DRIVE BELT
CONNECTION
it is Important that the belt from
PTO to collector (Part No C22-
8734-00) is crossed over in the
correct direction (fig 48) before
being fitted over the collector
pulley. The easiest way to do
this is to place the belt on the
PTO pulley and then stand
behind the tractor holding the
belt with two hands. Turn the
right hand above the left and fit
the belt on to the collector
pulley (7).
To check that you have this
right - start the tractor and
engage the PTO lever and
check that the brush is
revolving against the forward
direction of the tractor, (see
page 25 fig 47)
CORRECT BELT TENSION
To check tension:
1. Lower the collector to the
operating position and check
the tension using a spring
balance and a ruler.
2. Select a place on the belt
midway between the PTO
pulley and the Collector pulley.
3. Pull and measure the
deflection using the ruler (fig
43). It should be 19mm (3/4”)
at 2Kg (4 to 5Lbs).
If the tension needs to be
adjusted - first:
1. Remove the Collector from
the tractor.
2. Locate the adjustment holes
on the Locking Arms. These
holes take the nuts and bolts
on which the Locking Arm
hinges.
3. To increase tension on the
belt undo each nut and bolt
and relocate them one or more
holes forward (towards the
tractor). To slacken move the
bolts back . Ideally the bolts
should be in the same hole on
each Locking Arm, however
fine adjustment to get the right
tension may only permit you to
move one bolt - this is OK but
there should not be more than
one hole difference from side to
side.
4. Replace the Collector on the
tractor and re-check the belt
tension.

1. First remove collector from
the tractor.
2. To remove the plastic cover
remove the two nuts and bolts
(A) using a 1/2” spanner and
socket.
3. Using a 1/2” spanner and
socket slacken the nut and bolt
(B) holding the tension pulley
and slide the pulley out of the
way.
4. Remove the belt and fit the
Hayter replacement (Part No
C22-8328-00)
5. Tension the belt by sliding
back and securing the belt
tensioner. The tension is not
critical but the belt must not be
too tight. The ideal is 13mm
(1/2”) deflection at 2Kg (4/5
lbs) pull - use a spring balance
and ruler or tape to check.
6. Make sure that the
rectangular cover plate fits over
the adjustment slot - failure to
do this will allow cuttings and
grit to accumulate and damage
the pulleys and belt assembly.
7. Replace the plastic cover.
