Checking A Mismatch Between Mower Decks - Toro Groundsmaster 5910 Operator's Manual

Adjusting the Gage Wheels
1. Remove the bolt and nut securing the gage wheel to
the mower-deck brackets
2. Align the roller and spacer with the top holes in the
brackets and secure them with the bolt and nut.
Checking a Mismatch Between
Mower Decks
Due to differences in grass conditions and the counterbalance
setting of the traction unit, you should cut the grass and check
the appearance before you begin cutting the entire area.
1. Set all mower decks to the desired height of cut; refer
to Adjusting the Height of Cut (page
2. Check and adjust front and rear tire pressure.
Note: The correct air pressure in the front tires is 345
kPa (50 psi) and the rear tires is 207 kPa (30 psi).
3. Check and adjust all castor tire pressures to 345 kPa
(50 psi).
4. Check the lift and counterbalance pressures with engine
at H using the test ports; refer to
IGH IDLE
the Hydraulic-System Test Ports (page
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 you need to adjust a mower deck, find a flat surface
using a 2 m (6 ft) or longer straight edge to ensure that
the surface is flat.
8. To ease measuring blade plane, raise the height of cut
to the highest position; refer to
of Cut (page 27).
9. Lower the mower decks onto the flat surface and
remove the covers from the top of the mower decks.
Side Mower Decks
1. Rotate the blade of each spindle until the ends face
forward and backward.
2. For the outside blade spindle only, equally adjust the
shims on the front caster forks to match the desired
height of cut.
3. Measure from the floor to the front tip of the cutting
blade.
4. Rotate the blade 180° and measure from the floor to
the tip of the cutting blade.
Note: The rear of the blade should be 7.5 mm (0.3
inch) higher than the front.
Note: If you need to make an adjustment, adjust the
shims on the rear caster forks.

Checking for a Bent
Adjusting the Height
Matching the Height of Cut Between
Mower Decks
1. Position the blade side to side on the outside spindle
of both side mower decks.
2. Measure from the floor to the tip of the cutting edge
on both units and compare the measurements.
Note: These numbers should be within 3 mm (1/8
inch) of each other. Make no adjustment at this time.
3. Position the blade side to side on the inside spindle
of side mower deck and the corresponding outside
spindle of the front mower deck.
4. Measure from the floor to the tip of the cutting edge
on the inside edge of the side mower deck to the
corresponding outside edge of the front mower deck
and compare.
Note: The side mower-deck caster wheels should
remain on the ground with counterbalance applied.
Note: If you need to make an adjustment to match
the cut between the front and side mower decks, make
them to the side mower decks only.
5. If the inside edge of the side mower deck is too high
relative to the outside edge of the front mower deck,
remove 1 shim from the bottom of the front, inside
caster arm on the side mower
Figure 32).
Note: Check the measurement between the outside
edges of both side mower decks and the inside edge
of the side mower deck to outside edge of the front
mower deck again.
