Adjusting the Mower-Deck
Rollers
The mower-deck rollers should be mounted in the
lower position when operating at height of cuts greater
than 64 mm (2-1/2 inches), and in the higher position
when operating in height of cuts lower than 64 mm
(2-1/2 inches).

Correcting a Mismatch
Between the Mower Decks
Due to differences in grass conditions and the
counterbalance setting of the traction unit, a sample
area of grass should be cut and the appearance
checked before formal cutting is started.
1. Set all mower decks to the desired height of cut;
refer to Adjusting the Height of Cut (page
2. Check and adjust the air pressure in the front
and rear tire of the machine to 172 to 207 kPa
(25 to 30 psi).
3. Check and adjust the air pressure in all of the
caster tires for the mower deck to 345 kPa (50
psi).
4. Check the charge and counterbalance pressures
with the engine at
ports.
Note:
Adjust the counterbalance to 2241 kPa
(325 psi).
5. Check for bent blades; refer to
Bent Blade (page
6. Cut grass in a test area to determine if all mower
decks are cutting at the same height.
7. If mower-deck adjustments are still needed,
find a flat surface using a 2 m (6 ft) or a longer
straight edge.
8. To ease measuring the blade plane, raise the
height-of-cut to 7.6 to 10.1 cm (3 to 4 inches);
refer to Adjusting the Height of Cut (page
, using hydraulic-test
HIGH IDLE
Checking for a

9. Lower the mower decks onto a flat surface and
remove the covers from the top of the mower
decks.
10. Loosen the flange nut, securing the idler pulley,
to release the belt tension on each mower deck.
