condition. Keep all shields and safety devices in
place. If a shield, safety device or decal is defective
or damaged, repair or replace it before operating the
machine.
WARNING:
This machine is equipped with an interlock system
intended to protect the operator and others from
injury. This is accomplished by preventing the
engine from starting unless the deck drive is
disengaged, the transmission is in neutral, and the
neutral latches are in the neutral position. The
system shuts off the engine if the operator releases
the operator presence levers with the deck drive
engaged and/or the transmission not in neutral.
Never operate equipment with the interlock system
disconnected or malfunctioning.
C. Never remove the gas cap or add fuel with the
engine running. Allow the engine to cool before
fueling.

trailer.
E. Never store the machine or fuel container where
there is an open flame, spark or pilot light such as
on a water heater or other appliances.
F. Never fill containers inside a vehicle or on a truck
or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle
before filling.
G. Remove the machine from the truck or trailer and
fuel on the ground. If this is not possible, then
refuel the machine with a portable container,
rather than from a gasoline dispenser nozzle.
H. Keep the nozzle in contact with the rim of fuel
tank or container opening at all times until fueling
is complete. Do not use a nozzle lock-open device.

2. Adjust the steering brake rods so that the brakes do
not apply until the steering levers are pulled tight to
the handles. When the steering levers are locked in
the neutral position the machine should move freely.
CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is difficult
to suggest a cutter deck setting that will work for every
lawn. There are two adjustments that can be made on
these decks, 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 best cutting performance.
HEIGHT is the nominal distance the blade is off of the
ground. This measurement is made with the blades
pointed side to side and distance is measured between
cutting tip and ground. (Also see Blade Height Adjustment, next page).
Changes to the cutting height can be achieved by repositioning the cutter deck. (This adjustment will also effect
the pitch of the deck). There are three available positions
(See Figure 5).

Adjusting the blade height can be done by moving any
number of the five smaller 1/4" spacers on the blade
mounting bolts to the top of the spindle shaft or below the
spindle shaft.
-NOTE-
All blades should be positioned equally.
For best cut and discharge, a minimum of three spacers
should be installed between the blade and the spindle
(See Figure 7).
WARNING:
Blades have a sharp cutting edge. Wear proper
eye protection and protective gloves or wrap
blades with protective material when removing,
sharpening and installing blades.
CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade.
(See Figure 8).
-NOTE-
Dress the blade with a file. Using a wheel
grinder may burn the blade. Check the balance
of the blade. If blades are out of balance, vibration and premature wear of spindle assembly can
occur. See your authorized Scag dealer for
blade balancing or special tools, if you choose to
balance your own blades.

CUSTOM-CUT BAFFLE ADJUSTMENT
The Custom-Cut Baffle is designed to deliver optimum
airflow and superior cutting performance in any type of
grass. The Custom-Cut Baffle can be raised or lowered
to precisely tailor the deck's performance for the type of
grass being cut. The baffle can be set in three (3)
different positions for optimum performance.
A. 3" Position - baffle is installed using the top set of
holes on the front baffle welded inside the cutter
deck. (See Figure 10). The Advantage cutter deck
will deliver the best quality-of-cut in very tall, wiry ,
tough to cut grass.
B. 3-1/2" Position (factory setting) - baffle is installed
using the middle set of holes on the front baffle
welded inside the cutter deck. (See Figure 11). For
general purpose cutting, place the Custom Cut Baffle
in the 3-1/2" position. This gives the best mix of
cutting performance in all types of grass.
C. 4" Position - baffle is installed using the bottom set
of holes on the front baffle welded inside the cutter
deck. (See Figure 12). Placing the baffle in the 4"
setting will enhance fall cutting (leaf pickup) and
reduce cutter deck "blowout".
TO ADJUST THE CUSTOM-CUT BAFFLE
HEIGHT:
2. Move the Custom-Cut Baffle to desired position. (See
Figures 10 through 12 for position)
3. Reinstall the mounting hardware as shown. (See Figures
10 though 12). Torque hardware to 39ft.lbs.
