Routine Maintenance
PTO Main Drive Belt
The PTO drive belt is self-tensioning when the drive is
engaged. If this belt does require any adjustment it
should be carried out by your dealer; anyone not familiar
with this setting may cause serious damage or even injury
when using a machine with badly adjusted belts.
Accessory Drive Belt Installation (Fig 34, 35)
1.
Lift the PTO Guard.
2.
Place the drive belt over the PTO pulley of the
Powered Grass Collector.
3.
The lower half of the belt is pulled left and through
the belt hook.
4.
Feed the belt around the PTO pulley clockwise.
5.
Lock the Locating Lever over the Lift Arm Lugs.
6.
Check Belt Tension - (19mm deflection 2kgs
pressure).
7.
Rotate the locking clips over the Locating Lugs.
If the Belt Tension is incorrect, movement of the sweeper
Locking Levers on the threaded rod can adjust it. Ensure
the lock nuts are suitably tightened after adjustment. Belt
tension should be set in the working position.

Mulch Mowing
Mulch Mowing (Fig 23)
Mulching can save time, avoids creating piles of rotting
cuttings and feeds your lawn. When Mulch mowing it is
necessary to observe certain rules:
1.
Reduce the height of the grass by no more than
1/3
rd
its height in each pass. If the grass has grown
long make several passes to achieve the cut height
you require.
2.
Run the engine at maximum speed.
3.
Mow often, particularly in spring and early summer.
Short clippings of 25mm (1”) or less decompose
more quickly.
4.
If an unsightly residue of cuttings is being left –
increase the cutting height.
5.
Drive forward at a speed that does not cause the
engine speed to drop.
6.
Vary the mowing pattern from cut to cut.
7.
Always keep the underside of the cutting deck
clean to ensure good grass flow.
8.
Always check that the blades are sharp and in good
condition – never attempt to sharpen or replace
them yourself. New Westwood blades are not
expensive; it is good practice to ask your dealer
to change them.
High Grass Mulch Deck - (Fig 24)
The real alternative when cutting long or paddock grass is
the “high grass mulch” deck. When using the high grass
mulch deck please ensure the following:
1.
When cutting very tall grass set the deck at the
higher settings 7-9.
2.
Drive forward at a speed that does not cause the
engine speed to drop.
3.
Regularly check the cutter deck drive belt tension
in accordance with the instructions (page 13).
