It is not necessary to remove the complete blade holder
assembly to replace the blades. Blade bolts are accessible
through a hole in the top of the mower deck. Always re-
place both blades on a blade holder using two blades having
the same weight. Use only OEM replacement blades. (See
Figure 4-3)
A.
Raise rotary mower and securely block in position
B.
Remove nuts from blade bolts through the access
hole in the mower deck (Figure 4-3). The RC30
requires a 1

necessary.
D.
Assemble new blades to blade holder using
blade bolts, nuts, and lockwashers. Tighten nuts
to 325 ft./lbs.
