2. Check the air pressure of all four tires. If
needed, adjust to the recommended inflation;
refer to Tire Press.
3. Set the height-of-cut at 3 inch (76 mm).
4. Carefully rotate the blade(s) from side to side
(Figure 45). Measure between the outside
cutting edges and the flat surface (Figure 45).
If both measurements are not within 3/16 inch
(4.75 mm), an adjustment is required; refer to
steps 5 and 6.

Adjusting the Front-to-Rear
Blade Slope
Check the front-to-rear blade level any time you
install the mower. If the front of the mower is
more than 5/16 inch (7.9 mm) lower than the
rear of the mower, adjust the blade level using the
following instructions:
1. Position the mower on a flat surface.
2. Disengage the blade control switch and move
the control levers to the neutral locked position
and apply the parking brake.
3. Stop the engine, remove the key, and wait for
all moving parts to stop before leaving the
operating position.
4. Check the air pressure of all four tires. If
needed, adjust to the recommended inflation;
refer to Tire Pressure.
5. Check and adjust the side-to-side blade level
if you have not checked the setting; refer to
Leveling the Mower from Side-to-Side.
6. Measure the length of the rear trunion rod
(Figure 47). If the rod length is not 11-1/2 inch
(29.2 cm), remove the clevis pin and cotter
pin from the end of the rod (Figure 47),
loosen the jam nut, and turn the yoke until the
11-1/2 inch (29.3 cm) dimension is obtained.
7. Then secure the yoke with the clevis pin and
cotter pin. Repeat this procedure on the
opposite side of the mower.
