(I.E., the blades do not need to be “timed” nor synchro-
nized).
Hi-lift- These are generally the best cutting blades for
most grasses and mowing conditions. These blades
will provide extra “lift” for the thinner leaf grasses, will
handle lush grasses, and will provide maximum grass
and debris discharge. These blades are generally
required for material collection systems. More horse
-
power is required for these blades when compared to
others, and they generally produce the highest noise
levels.
Medium-lift- These blades require less horsepower
than the hi-lift, and they generally work well in wider
leaf grasses and some mulch applications.
Low-lift- These blades require less horsepower than
hi-lift and medium-lift blades, and they generally work
best with wide leaf grasses, sparse grass growth, and
sandy soil conditions. They generally produce the low
-
est noise levels. Bahia blades are configured without
offset, and with a maximum amount of sharpened cut
-
ting edge.
Mulch- These blades are generally designed for use in
cutting decks equipped with mulch baffles. The shape
of the blade generally produces higher turbulence in
order that the grass can be repeatedly cut and re-cut
into smaller pieces. These blades generally require
more horsepower than other blades. Mulch blades
work best when the grasses are cut at the highest lev
-
els, minimal lengths of grasses are removed, and grass
conditions are generally dry.

Remove six linchpins (See Fig. 9) (4) from
the deck and (2) from the front of the mower.
Remove the linchpins on the left and right
rear side of the cutter deck (2); remove the
linchpins on the left and right front side of the
cutter deck (2); and remove the linchpins on
the front of the mower (2).
