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 38.
4. Check that the blades and spindle shafts are not bent.
Refer to Checking for Bent Blades on page 48.
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
