2. Install the mower drive belt onto the mower center
pulley (Fig. 9). Ensure that it is on the upper center
pulley.
3. Install the mower drive belt onto the lower pulley and
the lower idler pulley in the pulley box (Fig. 9).
4. Turn the right knob on the front pulley box to tighten
the mower drive belt (Fig. 8). There needs to be a

Checking the Side-to-Side
Blade Cut
1. Check the tire pressure on the tractor. Refer to the
tractor operator's manual.
2. Position the blades side-to-side (Fig. 10). Measure at A
and B locations (Fig. 10) from a level surface to the
cutting edge of blade tips (Fig. 11).
3. The difference between measurements A and B should
be no more than a 1/4 inch (6 mm).

Adjusting the Side-to-Side
Blade Cut
This adjustment is available if necessary to compensate for
uneven side-to-side cut.
1. Adjust the side-to-side cut by adjusting the two carriage
bolts (Fig. 12) on the rear left of the mower.
2. After adjusting the carriage bolts, check the
side–to–side blade cut. Refer to Checking
the Side–to–Side Blade Cut (Fig. 12).
3. Repeat steps 1 and 2 until the difference is no more than
a 1/4 inch.

Checking the Front-to-Rear
Blade Slope
Check the front-to-rear blade slope any time you install the
mower.
1. Check the tire pressure on the tractor. Refer to the
tractor operator's manual.
2. Position one blade front-to-rear (Fig. 13). Measure at C
and either D location (Fig. 13) from a level surface to
the cutting edge of the blade tips (Fig. 14).
3. The mower blade should be 1/8–1/4 inch (4–7 mm)
lower in front at C than in the rear at D. Rotate the
blades and repeat for the other blades.
