Correcting the Mower
Quality-of-Cut
If a deck blade cuts lower than the other, correct it as follows:
Note:
Tire air pressure is critical in these procedures; make
sure that the rear tires have the correct pressure.
1.
Disengage the PTO and set the parking brake.
2.
Shut off the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3.
Disconnect the spark-plug wire(s) from the spark
plug(s).
4.
Adjust the tire pressure in the rear tires to 83 to 97 kPa
(12 to 14 psi).
5.
Check that the blades and spindle shafts are not bent;
refer to
Checking for Bent Blades (page 51)
.
6.
Set the height-of-cut to the 7.6 cm (3 inches) position;
refer to
Adjusting the Height-of-Cut (page 24)
.
Checking the Mower Deck Side-to-Side
Height
1.
Adjust the rear-tire pressure.
2.
Ensure that the blades are not bent; refer to
(page )
.
3.
Position the blades side-to-side.
4.
Measure at the
B
and
C
locations from a level surface
to the cutting edge of blade tips (
).

Measure from a level
surface
2.
Measure the blade at
points
B
and
C
5.
The difference between measurements
B
and
C
should
be no more than 6 mm (1/4 inch).
Note:
If it is not correct, refer to
(page )
.
Leveling the Mower Deck from Side to
Side
1.
Loosen the side nut and jam nut in the yokes you want
to adjust (
).

6.
Adjust these yokes to
adjust the left side of the
mower deck.
2.
Rotate the top bolt of the yokes to adjust the height of
the mower deck (
).
Note:
Rotate the bolts clockwise to raise the deck;
rotate the bolt counterclockwise to lower it.
3.
Tighten the jam nuts and side bolts.
4.
Check the side-to-side height; refer to
Mower Deck Side-to-Side Height (page 53)
