Adjusting The Mower-Deck Rollers; Correcting A Mismatch Between Mower Decks - Toro 30635 Operator's Manual

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).
1. Remove the bolt and nut securing the gage wheel to
the cutting unit brackets

2. Align the roller and spacer with the top holes in the
brackets and secure them with the bolt and nut.
Correcting a Mismatch
Between Mower Decks
Due to differences in grass conditions and the counterbalance
setting of the traction unit, cut a sample area of grass and
check the appearance before starting formal cutting.
1. Set all mower decks to the desired height of cut; refer
to Adjusting the Height of Cut (page
2. Check and adjust the front and rear tire pressures to
172 to 207 kPa (25 to 30 psi).
3. Check and adjust all of caster tire pressures to 345 kPa
(50 psi).
4. Check the charge and counterbalance pressures with
the engine at
HIGH IDLE
Note: Adjust the counterbalance to 2,241 kPa (325
psi).
5. Check for bent blades; refer to
Blade (page 61).
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 foot) 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
the Height of Cut (page
(Figure 25).

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.
Setting up the Front Mower Deck
1. Rotate the blade on each spindle until the ends face
forward and backward.
2. Measure from the floor to the front tip of the cutting
edge.
3. Adjust the shims (3 mm or 1/8 inch) on the front
caster fork(s) to match the height-of-cut decal
26); refer to
1. Tensioning cap
2. Spacers
