Cutting Deck Adjustments (cont'd)
an amount of material from
the
pad equivalent to
20%
of the movement
necessary
at the blade tip. Check the
mounting pad height occasionally to make certain you
are not removing too much material. Be sure the
mounting pad
is
flat
when complete. Recheck the
blade tip clearance to insure
it
is within specification
after adjusting the engine mounting pads. Always use
Loctite
(R)
when re-installing engine mounting bolts.
Blade Tip to Housing Clearance
is
the distance
be-
tween the end
of
the blade and the side of the deck
(and the discharge ramp). See Figure
127.
If
this
distance
is
too close, the blade tip may contact the
side
of the deck.
If
the clearance is too great, clumps or
streaks of grass clippings may result.
It
is also possible
that
the bag will not
fill
completely since the deck
will
lose some of
its
vacuum around the circumference of
the deck.
ADJUST MOUNTING PADS
(ONLY AS REQUIRED)

CAUTION
!
Do not adjust the engine mountlng pad
more than
1.5
mm
(.060").
If
the dimension
Is
still
out
of
specification after adjusting the engine mounting
pad,
deck replacement may be required.
The specification for blade to tip housing clearance is
given below.
Blade Tip Clearance
4.3
2
mm
(.I70
If
the clearance
is
not greater
than
2.3
mm
(.090'”)
around the circumference of the deck, loosen the
engine bolts, center the engine, then retighten the
bolts. Recheck to be sure that the blade to tip
clearance is now within the specification.
BLADE TIP
CLEAR
Figure
127
If
after centering the engine the clearance
is
still
not
consistent around the circumference, the deck may
be
warped do to manufacture, 'squeeze' type forklifts, or
operator abuse. Check with the Toro Consumer
Service Department if blade tip to deck Clearance
is
still
out of specification.
NOTE:
The distance from the blade tip to the discharge
ramp can have a significant effect on quality
of
cut. For
best
performance, adjust the ramp
as
close to the
blade
tip
as
possible but not less than
2.3
mm
(.090”).
Cutting Deck Repair
If
a foreign object
is
picked up by the blade, the deck
may
be
damaged. Small cracks may
be
repaired by
welding.
If
cracks are large, or
if
pieces are missing,
the deck should
be
replaced.
CAUTION! Because the deck is aluminum, it is
imperative
that
only a welder experienced
in
aluminum
welding be used.
If
not, damage to the deck or
compromised structural integrity may result.
A
#380
aluminum welding rod used
in
conjunction with
an
inert gas type welder
is
recommended.
