CUTTER DECK ADJUSTMENTS
Due to the many conditions that exist, it is
difficult to suggest a setting that will work for every
lawn. There are, however, two adjustments that
should be made on the cutter deck: pitch and
height.
PITCH is the angle of the blades (comparing
front to rear). A 1/4" downward pitch (front of
deck down) is recommended for better cutting
performance.
HEIGHT is the nominal distance that the
blade is off the ground. This measurement is made
with the blades pointed side to side and distance is
measured between cutting tip and ground.
Adjusting the blade height can be done by
moving any number of the five smaller spacers on
the blade mounting bolts to the top of the spindle
shaft or below the spindle shaft. All blades should
be positioned equally (see Spindle Illustration, p. 8).
ADJUSTMENTS (cont'd)
3. To adjust the blade drive belt: Using a belt tension
gauge, check the belt tension so that the belt moves 1/2"
with 10 pounds of pressure.
Adjust the tension by tightening or loosening the J-bolt.
BELT ALIGNMENT
Belt alignment is important for proper performance of your
Scag mower. If you experience frequent belt wear or
breakage, see your authorized Scag service dealer for belt
adjustment.

For cutting in the lowest position, mount the
cutter deck in the top hole (A). For cutting in
the highest position, mount the deck in the
lowest hole (C). Setting the cutter deck height
will be determined by the type of cutting
conditions.
Caster spacers also can be repositioned to
change cutting heights and to change the pitch
of the deck (see figure below).
To adjust caster spacers, raise the deck and
remove pin and caster wheel. Reposition
caster spacers as needed then replace caster,
top spacers and pin. Make the same adjust-
ments on the other caster wheel.
TAPERED BEARING SPINDLE ASSEMBLY
The cutter deck is shipped with one spacer on top
of spindle and four underneath (see figure below).
-NOTE-
For best results, keep the cutter deck
high in relation to the engine deck and
the blades low in the cutter deck; ie. 3 or
4 spacers below the spindle shaft.
Additional range to the cutting height can be
achieved by repositioning the cutter deck in
relationship to the engine deck. This adjustment
also effects the pitch of the deck. There are three
positions for mounting the cutter deck (see figure
following column).

1. Connect BOTH steering control rods into the steering
control lever up on the handles. Do not install the
hair pin through the rod at this time.
2. Put the steering control lever control rod into the
neutral latch. (See figure on page 10).
5. Observe the drive wheels. If they rotate, loosen
the bolts on the neutral adjustment handle and
move the handle up or down until the wheels are
in neutral (up for reverse and down for forward).
(See figure above).

10
-NOTE-
Make sure that the adjustments on page 9 have
been completed, the neutral latch is engaged
and that the speed shift lever is in neutral.
1. Place the speed adjustment bearing lever where the
bearing just contacts the speed adjustment cam. (See
figure below).
TRACKING STRAIGHT ADJUSTMENT
-NOTE-
Before making this adjustment be sure that
the tire pressure has been checked and that
it is correct. (See page 9)
-NOTE-
This adjustment will allow the machine to
travel in a straight line at the normal oper-
ating speed.
