the end of the sail area only (Figure 76). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 79).
Important:
The curved part of the blade must
be pointing upward toward the inside of the
mower to ensure proper cutting.
2. Install the spring disk and blade bolt. The spring
disk cone must be installed toward the bolt head
(Figure 79). Torque the blade bolt to 85-110 ft-lb
(115-150 N-m).

Correcting the Mower Quality
of Cut
If one deck blade cuts lower than the other, correct as
follows.
Note:
Tire air pressure is critical in these procedures.
Make sure the rear tires have correct pressure.
1. Disengage the PTO and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position. Disconnect the spark plug wire(s) from
the spark plug(s).
3. Adjust the tire pressure in the rear tires to 12-14 psi
(83-97 kPa).
4. Check that the blades and spindle shafts are not
bent. Refer to Checking for Bent Blades.
5. Set the height-of-cut to the 3 inch (7.6 cm) position.
Refer to Adjusting the Height-Of-Cut in Operation.
6. Perform the steps in the following procedures in
order.
Checking the Mower Deck Side-to-Side
Height
1. Adjust the rear tire pressure.
2. Ensure the blades are not bent. Refer to Checking
for Bent Blades.
3. Position the blades side-to-side. Measure at
B
and
C
locations from a level surface to the cutting edge
of blade tips (Figure 80).

4. The difference between measurements
B
and
C
should be no more than 1/4 inch (6 mm). I If it is
not correct, proceed to Changing the Mower Deck
Side-to-Side Height.
Changing the Mower Deck Side-to-Side
Height
Changing the side-to-side height is done by adjusting
the rear tire pressure and U-plates on the side of the
engine deck.
