Engine to Cutter Drive Belt Tension

The correct tension of the Cutter Drive Belt is critical. 
If incorrectly set it can lead to engine damage and
invalidate warranty.

To check the tension put the deck in a middle cutting
height position.

1. 

Select a midway position on the belt, using a spring 
balance; apply a 2Kg (4-5lbs) pull (figure 31).

2. 

Using a ruler or tape, measure the deflection 
achieved which must be 13mm (1/2”). If more, the 
belt tension must be increased, if less – decreased.

To correct the tension, follow this procedure:

1. 

Release the tension on the belt by pulling the Belt 
Tension Lever (page 12, figure 27) forward.

2. 

Taking care not to burn yourself on a hot exhaust, 
locate the Trunnion at the end of the Belt Tension 
Rod – lift the bonnet and look to the front (nearside)
close to the exhaust (see Figure 32).

3. 

Remove the spring clip and washer holding the 
Trunnion in place on the Deck Tension Cradle 
(Figure 33) and release the Trunnion so it can 
be turned.

4. 

Both the Trunnion and the Belt Tension Rod are 
threaded. The  belt tension is increased by turning 
the Trunnion towards the end of the Rod and 
reduced by winding in the reverse direction.

5. 

Having made the adjustment, re-locate and secure 
the Trunnion, re-tension the Belt with the Belt 
Tension Lever – then re-check the Belt tension.

Transmission Drive Belt

The transmission drive belt is self-tensioning.  When the
hand brake is released and the drive belt engaged, the
belt will retain its tension correctly.  When the drive is 
dis-engaged using the hand brake, the park brake

engages.  This setting is adjustable but should be carried
out by your dealer, anyone not familiar with this setting
may cause serious damage to the transmission.

Routine Maintenance

Engine Maintenance

Please refer to the engine manufacturer’s handbook
enclosed with this manual.

Battery Maintenance (Fig 26)

The battery fitted to your tractor is a low maintenance
sealed unit.  Should your battery require charging for any
reason please note that sealed lead acid batteries require
a special 2 stage charging unit.  Any battery charged on a
standard battery charger will fail prematurely.  Your dealer
will be able to supply a battery charger specifically
designed for the battery fitted to your tractor. The battery
charger part number is 44-95628-00. If your tractor does

not start, refer to the troubleshooting section in this manual.

Cutter Deck Maintenance

REMOVAL OF CUTTER DECK (Fig  27, 28, 29 & 30)

The Cutter Deck can be quickly removed for servicing or
cleaning, or to give greater clearance when driving or
towing over uneven ground.

Follow this sequence:

1. 

Lower the cutting deck to its lowest position 
(see Controls - Page 7).

2. 

De-tension the Cutter Drive Belt with the lever 
under the left running board (Figure 27).

3. 

Remove the 3 securing pins from the front of the 
deck (Figure 28 - A, B & C) by undoing the 
Rue Clips (Figures 29 & 30) and removing them.

4. 

Remove the 2 securing pins from the back of the 
deck (Figure 28 - D and E).

5. 

Slip the cutter drive belt off the Engine Pulley.

6. 

Slide the deck out.

7. 

If you are going to use the tractor without the deck, 
remove the Securing Bar (Figure 28 - F).

8.

Remove the fifth wheel  - G (V20/50 only).

To Clean the Cutter Deck

Remove the deck as instructed, stand it on its side and
hose off accumulated cuttings. DO NOT SPRAY WATER
DIRECTLY ONTO BEARING HOUSINGS. To prevent a
drop in performance it may be necessary to routinely
check for this grass build up, particularly at the beginning
of the season when the grass is lush and wet. It is best to
regularly check and clean the Cutter Deck as often as
possible, this can be done by either removing the Deck or
raising the tractor safely on a ramp.
