Checking the cutting unit’s
parallelism
Check the cutting unit’s parallelism as follows:
1 Check the air pressure in the tyres 60 kPa/0.6 kp/cm
2
/8.5
PSI.
2 Place the machine on a flat surface.
3 Put the lifting lever in the mowing position.
4 Measure the distance between the ground and the front
and rear edges of the cutting unit hood.
The cutting unit
should have a slight slant, with the rear edge 2-4 mm (1/
8”) higher than the front edge.
Adjusting the parallelism of the
cutting unit
1 Remove the front hood and right-hand fender.
2 Undo the nuts on the lift strut.
3 Screw out (extend) the stay to raise the rear edge of the
co
ver.
Screw in (shorten) the stay to lower the rear edge of the
co
ver.
4 Tighten the nuts after adjustment.
5 On completion of the adjustment the unit’s parallelism
should be re-chec
ked.
6 Fit the right-hand fender and the front hood.
Replacing the cutting unit belts
On these cutting units with collision-proof blades, the blades
are driven by one V-belt. Do as follows to change the V-belt:
1 Remove the cutting unit.
2 Open the lock for the track rod bolt.
3 Unscrew the bolts holding the unit frame bracket.
4 Remove the lock and pass the unit frame out.
5 Remove the two bolts on the unit frame.
6 Remove the bolt so the track rod is released in one end.
!
WARNING! Wear gloves to protect your
hands when working with the blades.
There is a risk of crush injuries when
working with the belt.
