ASSEMBLY
4. Turn the mower deck over for blade installa-
e tion, and adjustment.
Fig.4
If the blade(s) is raised, the cutting height
spacers removed from above must be replaced
below Ahe blade(s). Unless the desired cutting
height is known, it is recommended that three
cutting height spacers be used below the blade(s)
This gives an average cutting height. Always
re-install all the cutting height spacers either above
or below the blade(s).
The cutting height is determined by the place-
ment of the cutting height spacers above or
below the blade. Each cutting height spacer
changes
the cutting height by 1/
4"
(6.35 mm).
One cutting height spacer must ALWAYS be
installed
below the blade(s). The twin blade
assembly has a
1/8" spacer and should be in-
stalled above the blade(s).
Install
three cutting height spacers (item 8), blade
(item 12), the remaining spacers and nut (item 13).
Torque nut to 100 ft. Ibs. (135.6 Nm).

ing reduces the action. The swivel action should
be
only loose enough to allow the mower to
follow ground contour.
2. The cutting height of the mower is adjusted by
the cutting height spacers. See paragraph 5&6
of ASSEMBLY. e
