Installing the Blades
1. Install the blade onto the spindle shaft
(Figure 71).
Important:
The sail part of the blade
must be pointing upward, toward the
inside of the mower to ensure proper
cutting (Figure 71).
2. Install the flat washer, lock washer, and blade
bolt (Figure 71).
3. Torque the blade bolt to 85-110 ft-lb (115-140
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 all 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 all tires to
specifications on page .
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 4 inch (101.6 mm)
position. Refer to Adjusting the Height-Of-Cut
in Operation, page 20.
6. Perform the steps in the following sections
Frame Set Up, Checking Front-to-Rear Pitch,
and Checking Side-to-Side Leveling.
Frame Set Up
Checking the Carrier Frame and Deck
Alignment
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.
3. Place a long straight edge on top of the engine
deck as shown in Figure 74.
4. At the carrier frame cross tube, measure
the height at location A (Figure 74). This
measurement must be 1-5/16 inch (33 mm),
plus or minus a 1/4 inch (6 mm).
5. If the height at location A is not correct,
adjustment is needed.
6. Loosen the carrier frame mounting bolts on
both sides of the machine (Figure 74).
7. Align the carrier frame and engine deck to
match 1-5/16 inch (33 mm), plus or minus a
1/4 inch (6 mm) at location
A (Figure 74).
8. Tighten the carrier frame mounting bolts on
both sides of the machine.

Checking the Engine Deck Height
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.
3. Adjust the tire pressure in all tires.
4. Measure engine deck height at location A
(Figure 75).
