Installing the Blades
Important: The sail part of the blade must be
pointing upward, toward the inside of the mower to
ensure proper cutting (Figure 53).
1. Install the blade, stiffener, curved washer, and blade
bolt to the spindle (Figure 53).
2. 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 the
rear tires to specifications; refer to
Drive System Maintenance (page 27) .
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 11).
6. Perform the steps in the following sections Frame
Set Up, Checking Front-to-Rear Pitch, and Checking
Side-to-Side Leveling.

Checking the Carrier Frame and Engine
Deck Alignment
Note: Misalignment can cause excess wear on the PTO
drive belt.
2. Balancer
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 54.
4. At the carrier frame cross channel, measure the
height at location A (Figure 54). 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 54).
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 54).
