Tire Pressure

WARNING! 

Maximum tire pressure under any 

circumstances is 30 psi. Equal tire pressure should be 

maintained at all times. Never exceed the maximum 

inflation pressure shown on the sidewall of the tire.

The recommended operating tire pressure is:

• 

Approximately 10 psi for the rear tires 

• 

Approximately 14 psi for the front tires

IMPORTANT: 

Refer to the tire sidewall for exact tire 

manufacturer’s recommended or maximum psi. Do not 

overinflate. Uneven tire pressure could cause the cutting deck to 

mow unevenly.

Attaching The Steering Wheel 

If the steering wheel for your tractor did not come attached, the 

hardware for attaching it has been packed within the steering 

wheel, beneath the steering wheel cap. Carefully pry off the 

steering wheel cap and remove the hardware.
1. 

With the wheels of the tractor pointing straight forward, 

place the steering wheel over the steering shaft.

2. 

Place the washer (with the cupped side down) over the 

steering wheel and secure with the hex bolt. See Figure 

3-3. 

3. 

Place the steering wheel cap over the center of the steering 

wheel and push downward until it “clicks” into place.

Figure 3-3

Attaching The Seat

If the seat for your tractor was not attached at the factory, refer 

to the following steps.

NOTE: 

For shipping reasons, seats are either fastened to the 

tractor seat’s pivot bracket with a plastic tie, or mounted 

backward to the pivot bracket. In either case, free the seat from 

its shipping position and remove the adjustment knob from the 

bottom of seat before proceeding with the instructions below.
1. 

As already instructed, remove the seat adjustment bolt 

installed by the factory in the bottom of the seat. See “a” in 

Figure 3-4.

2. 

Align the seat over the seat pivot bracket as shown in 

Figure 3-4 and fit the seat onto the pivot bracket inserting 

the two tabs on the seat bottom into the slots on the pivot 

bracket.

3. 

Slide the seat rearward in the seat pivot bracket (c), 

lining up the center rear slot in the pivot bracket with the 

remaining hole in the seat’s base.  See 

Figure 3-5.

Note: 

Be certain the two seat tabs engauge the pivot 

bracket as shown in the bottom inset of Figure 3-5.

4. 

Select desired position for the seat, and secure with the 

adjustment bolt removed earlier (d in Figure 3-5).
