Installing the Blades
1. Install the blade onto the spindle shaft
(Fig. 69).
Important
The sail part of the blade must be pointing
upward, toward the inside of the mower to ensure proper
cutting
(Fig. 69).
2. Install the flat washer, lock washer and blade bolt
(Fig. 69).
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.
3. Adjust the tire pressure in all tires to specifications on
page 39.
4. Check that the blades and spindle shafts are not bent.
Refer to Checking for Bent Blades on page 49.
5. Set the height-of-cut to the 4 inch (101.6 mm)
position. Refer to Adjusting the Height-Of-Cut in the
Operation section.
6. Perform steps in the following sections Frame Set Up,
Checking Front–to–Rear Pitch and Checking
Side–to–Side Leveling.
Frame Set Up
Checking 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 72.
4. At the carrier frame cross tube, measure location A
height (Fig. 72). 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 (Fig. 72).
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 (Fig. 72).
