Correcting Cutting Unit
Mismatch
If one cutter blade cuts lower than the other, correct
as follows:
1.
Stop the engine, remove the key and disconnect
the spark plug wire(s) from the spark plug(s).
2.
Adjust the tire pressure in all tires to
specifications and check that the blades are not
bent. Refer to Checking for Bent Blades on page
11.
3.
Set the height-of-cut to the 2-1/2" position.
Refer to Adjusting the Height-Of-Cut in the
Operation section. Make sure the clevis pins are
resting on the frame cushions.
4.
Rotate the blades so the tips line up with one
another. The blade tips must be within 1/8"
(3 mm) of each other. If the blade tips are not
within 1/8" (3 mm) of each other, add shims
(Part No. 3256-24) between the appropriate
spindle housing and the bottom of the cutting
unit to align the blades.
Setting the Front-to-Rear Pitch
1.
Check the tire pressure.
2.
Position the blades front-to-rear (Fig. 17).
Measure at "C" and "D" locations (Fig. 17) from
a level surface to the cutting edge of the blades
(Fig. 18).
3.
The mower should be 1/8"–5/8" (3–16 mm)
lower in front "C" than in the rear "D".
