Checking A Mismatch Between Mower Decks - Toro Groundsmaster 5900 Operator's Manual

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 mowing 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 the front and rear tire pressure.
Note:
The correct air pressure in the front tires
is 220 kPa (32 psi) and the rear tires is 207 kPa
(30 psi).
3. Check and adjust all caster tire pressures to 340
kPa (50 psi).
4. Check the lift and counterbalance pressures with
the engine throttle at HIGH IDLE using the test
ports; refer to Inspecting the Hydraulic System
Test Ports (page
5. Check for bent blades; refer to
Bent Blade (page
6. Cut grass in a test area to determine if all mower
decks are mowing 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 the blade plane, raise the
height of cut to the highest position; refer to
Adjusting the Height of Cut (page
9. Lower the mower decks onto the flat surface and
remove the covers from the tops of the mower
decks.
Wing 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
mowing blade.
4. Rotate the blade 180° and measure from the
floor to the tip of the mowing 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.

Matching the Height of Cut
Between Mower Decks
1. Position the blade side to side on the outside

2. Measure from the floor to the tip of the
cutting edge on both units and compare the
measurements.

(1/8 inch) of each other. Make no adjustment
at this time.
3. Position the blade side to side on the inside
spindle of the wing 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 wing mower deck
to the corresponding outside edge of the front
mower deck and compare.
Note:
wheels should remain on the ground with
counterbalance applied.
Note:
match the cut between the front and wing mower
deck, make them to the wing mower decks only.
5. If the inside edge of the wing 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 wing mower
deck (Figure 43
