MOWER DECKS
8. Lift up on four top chain attachment bolts, in the
slots, to take slack out of chains and tighten flange
lock nuts. (Deck is still supported by two rear and
one front blocks under mower.)
9. If bolts contact the end of slots, shorten or
lengthen rod/swivel assemblies as required, for
extra clearance, adjust each side same amount.
Note: When properly adjusted, the front blade tip will
be slightly lower than the rear blade tip. Refer to
"Checking for Bent Blades" on page 6 - 11 to measure.
10. Recheck that blocks just fit just under the mower
and that tension on all four chains is
approximately equal. Tighten chain attachment
bolts securely.
11. Measure height of cut. This can be checked with
the same procedure as "Checking for Bent
Blades" on page 6 - 11.
12. Install anti-scalp rollers for proper height-of-cut
and tighten securely.
Checking for Bent Blades
1. Rotate the blades until the ends face forward and
backward (Figure 131). Measure from a level
surface to the cutting edge of the blades (Figure
132). Note this dimension.
Figure 131
m-1078
Figure 132 m-2539
2. Rotate the opposite ends of the blades forward.
Measure from a level surface to the cutting edge
of the blades at the same position as in step 1
above. The difference between the dimensions
obtained in steps 1 and 2 must not exceed 1/8”
(3mm). If this dimension exceeds 1/8” (3mm), the
blade is bent and must be replaced.
WARNING
A blade that is bent or damaged could break
apart and could seriously injure or kill you or
bystanders.
• Always replace bent or damaged blade with a
new blade.
• Never file or create sharp notches in the edges
or surfaces of blade.
