Tires
WARNING: For proper traction and deck leveling the maximum
recommended tire pressure is 12 psi. Equal tire pressure should be
maintained at all times. NEVER exceed the Maximum PSI noted on the tire
side wall.
Check the tire air pressure after every 50 hours of operation or weekly. Keep the tires
inflated to the recommended pressures. Improper inflation will shorten the tire service life
and produce an uneven cut. Observe the following guidelines:
Rear Tires — 10-12 psi (69-82.7 kPa) max recommended operating pressure.
Front Tires — N/A - Front tires are semi pneumatic and do not require inflation.
• Do not inflate a tire above the operational pressure of 12 psi (82.7 kPa).
• Do not reinflate a tire that has been run flat or seriously under inflated. Have it
inspected and serviced by a qualified tire mechanic.

Parking Brake Check/Adjustment - 36 Inch Deck Only
Check the parking brake engagement after every 50 hours of operation or weekly. The
brake wedges should firmly engage with the tires, pressing down into the tire tread and
keep the mower from moving. Perform the following to check and if necessary, adjust the
brake wedge to maintain engagement as the tire tread wears:
1. Check rear tire air pressure to ensure both rear tires are inflated to the recommended
pressure (10-12 psi (69-82.7 kPa) max recommended operating pressure).
2. With the parking brake disengaged, measure the gap between the brake wedge (a)
and the rear tire (b) on both sides of the mower. This measurement must be ½ to 3/4
(12.7mm - 19mm).
3. If the gap between the brake wedge and tire is between ½ and 3/4 inches (12.7mm -
19mm) go to STEP 5. Otherwise go the STEP 4 to adjust brake wedges.
4. If necessary, perform the following to adjust the brake wedges:
a. Disengage the parking brake.
b. Remove the two hex bolts (c) and locknuts (d) securing the brake wedge (a) to the
brake wedge bracket (e).
c. Move the brake wedge up or down to one of five mounting positions (f ).
nOTE: Each mounting position will move the brake wedge 1⁄4 inch (6.4 mm) up or
down.
d. Using the two hex bolts and locknuts, secure the brake wedge to the brake
wedge bracket.
e. Ensure the gap between the brake wedge and tire is between ½ and 3/4 inches
(12.7mm - 19mm).
5. If necessary repeat STEPS a - d to adjust the remaining brake wedge.
6. Engage the parking brake and ensure the brake wedge engages and presses into the
tire on both sides of the mower. If necessary repeat STEPS 1-6 until the brake wedges
should firmly engage with the tires, pressing down into the tire tread and keep the
mower from moving.
7. If the parking brake will not properly engage the tires stop use of mower and contact
the customer service representative for assistance.
