Vibration is generally a warning of trouble.
Check the machine for damaged or defective
parts. Repair any damage before starting the
engine or operating the cutter deck. Be sure the
blades are in good condition and the blade bolts
are tight.
MAINTENANCE AND STORAGE
10. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or
loss of control. Be especially cautious when
changing directions on slopes.
3. To reduce potential fire hazard, keep the engine
free of excessive grease, grass, leaves and accumulations of dirt.
1. Disconnect the spark plug wire from the spark
plug to prevent accidental starting of the engine
when servicing, adjusting or storing the machine.
2. If the mower must be tipped to perform maintenance or adjustment, remove the battery, drain
the gasoline from the fuel tank and the oil from
the crankcase.
4. Be sure the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check
the blade mounting bolts and nuts frequently to
be sure they are tightened.
WARNING:
DO NOT operate on steep slopes. To check a
slope, attempt to back up it (with the cutter deck
down). If the machine can back up the slope
without the wheels slipping, reduce speed and
use extreme caution. ALWAYS FOLLOW OSHA

-NOTEWhen the PTO is engaged or (possibly) disengaged, a squealing sound from the underside of
the machine is normal. It is caused by the
electric clutch plates meshing as the cutter
blades come up to speed. For best equipment
life, engage the clutch with the engine at 3/4
throttle, not under full load.
SGB003
WARNING:
Backward (Reverse) Operation - Depress Heel

ADJUSTMENTS
PARKING BRAKE
Minor brake adjustments can be made by loosening
the top nut on both brake cables (see figure 4).
Back the nuts off approximately 1/4". While pulling
one cable downward, tighten the bottom nut on the
cable until it touches the bottom of the brake cable
mount. Tighten both the top and bottom nuts to
lock the cable in place. Repeat the above steps for
the second brake cable. Make sure that both
cables are adjusted evenly so that the brakes do not
cause the mower to pull to the left or right.
If the drive wheels inconsistently rotate, i.e. drive
wheels sometimes rotate and sometimes do not
when foot pedal is not depressed, then check
neutral adjustment bolt for "zero free play" in neutral
control spring.
-NOTEIf there is free play in the foot pedal have your
SCAG servicing dealer inspect the machine
and repair it as needed.
4. If the drive wheels rotate in the forward travel
direction, turn the adjustment bolt clockwise until the
tire rotation stops. If the drive wheels rotate in the
backward travel direction, turn the adjustment bolt
counter-clockwise until the tire rotation stops (See
Figure 5).
-NOTEThis is a minor brake adjustment. If the
brakes do not function properly after this
adjustment, see your Scag Service Dealer
before operating your mower.

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.
Cutter Blade
Hex Head Bolt
Figure 10. Cutter Blade Adjustment
PITCH is the angle of the blades (comparing front
to rear).
-NOTEFor best results, keep the cutter deck
high in relation to the engine deck and
the blades low in the cutter deck; ie. 4 or
5 spacers below the spindle shaft.
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.
Additional range to the cutting height can be
achieved by repositioning the cutter deck in relationship to the engine deck. This adjustment also affects
the pitch of the deck.
8
There are three positions for mounting the cutter deck
(See Figure 11). 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.
CUTTER BLADES
CAUTION:
Blades have a sharp cutting edge. Wear protective
gloves or wrap blades with protective material when
removing, sharpening and installing blades.

-NOTEDress 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 can occur. See your authorized Scag Dealer for
blade balance tools.
Caster spacers also can be repositioned to change the
cutting heights and to change the pitch of the deck (See
Figure 12).
To adjust the caster spacers, raise the deck and remove
the pin and caster wheel. Reposition the caster spacers
as needed, then replace the caster, top spacers and pin.
Make the same adjustments on the other caster wheel.
To adjust the blade height, move any number of the five
1/4" thick spacers on the blade mounting bolts to the
top of the spindle shaft or below the spindle shaft.

LIMITED WARRANTY-COMMERCIAL EQUIPMENT
Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judgment
of Scag, to be defective in materials or workmanship, will be repaired or replaced by an Authorized Scag Service Dealer
without charge for parts and labor. This warranty is limited to the original purchaser and is not transferable. Proof of
purchase will be required by the dealer to substantiate any warranty claims. All warranty work must be performed by an
Authorized Scag Service Dealer.
This warranty is limited to the following specified periods from the date of the original retail purchase for defects in
materials or workmanship:
* Wear items including drive belts, blades, hoses and tires are warranted for 90 days.
* Batteries are warranted for 90 days.
* Frames, decks, and structural components including oil reservoirs and oil coolers
are warranted for 1 year.
* Engines and electric starters are warranted by the manufacturer’s warranty period.
* Hydro-Gear® drive components are warranted by Hydro-Gear, Sullivan, IL.
* Drive system components are warranted for 1 year by the component manufacturer, in
conjunction with Scag Power Equipment. (Excluding fittings, hoses, cooling systems,
oil reservoirs, and drive belts).
* Electric clutches have a Limited Warranty for 2 years (parts and labor 1st year; parts only
2nd year).
* Cutter Spindle Assemblies 46631 have a Limited Warranty for 3 years (parts and
labor 1st year; parts only 2nd and 3rd years).
Any Scag product used for rental purposes is warranted by a 90-day warranty period.
The Scag mower, including any defective part must be returned to an Authorized Scag Service Dealer within the warranty
period. The expense of delivering the mower to the dealer for warranty work and the expense of returning it to the owner
after repair will be paid for by the owner. Scag’s responsibility is limited to making the required repairs and no claim of
breach of warranty shall be cause for cancellation or rescission of the contract of sale of any Scag mower.
This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has
been operated in any way contrary to the operating instructions as specified in the Operator’s Manual. The warranty does
not apply to any damage to the mower that is the result of improper maintenance, or to any mower or parts that have not
been assembled or installed as specified in the Operator’s Manual and Assembly Manual. The warranty does not cover
any mower that has been altered or modified, changing performance or durability. In addition, the warranty does not
extend to repairs made necessary by normal wear, or by the use of parts or accessories which, in the reasonable judgment
of Scag, are either incompatible with the Scag mower or adversely affect its operation, performance or durability.
Scag Power Equipment reserves the right to change or improve the design of any mower without assuming any
obligation to modify any mower previously manufactured.
All other implied warranties are limited in duration to the one (1) year warranty period or ninety (90) days for mowers
used for rental purpose. Accordingly, any such implied warranties including merchantability, fitness for a particular
purpose, or otherwise, are disclaimed in their entirety after the expiration of the appropriate one year or ninety day
warranty period. Scag’s obligation under this warranty is strictly and exclusively limited to the repair or replacement of
defective parts and Scag does not assume or authorize anyone to assume for them any other obligation. Some states do
not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for
gasoline, expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner,
mechanic’s travel time, telephone or telegram charges, rental of a like product during the time warranty repairs are being
performed, travel, loss or damage to personal property, loss of revenue, loss of use of the mower, loss of time or inconvenience. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
