2. Before starting the engine:
* Check the oil level in the engine and the hydraulic reservoir.
* Fill the fuel tank with clean, fresh, lead-free gasoline.
* Open the fuel valve on the bottom of the fuel tank.
-NOTE-
Use gasoline with an octane rating no less than
87.
-NOTE-
When 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.
WARNING:
If you are not familiar with the operation of the hydrostatic drive, practice turning and maneuvering before engaging the cutter blades.
* The right hand foot pedal must be in the
NEUTRAL position.
* The blade clutch switch must be in the OFF position.
* The parking brake must be ON.
3. Start the engine:
* Choke as required. If the engine is cold, pull the choke knob out. When the engine starts, slowly push the choke in. If the engine stalls, repeat the above operation. When the engine is warm, choking may not be necessary.
5. Release the parking brake. Depress the right foot pedal at the toe end to drive forward (See Figure 1) or depress the pedal at the heel end to drive in reverse. (See Figure 2)
-NOTE-

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.
-NOTE-
This is a minor brake adjustment. If the brakes do not function properly after this adjustment, see your Scag Service Dealer before operating your mower.

2. Block the caster wheels to prevent an accident should the machine fall off the jack stands.
3. Start the engine and determine if the drive wheels rotate.
If the drive wheels consistently rotate when foot pedal control is in neutral, go to step 4.
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.
-NOTE-
If 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).
5. Check the adjustment of the right foot control pedal for full forward speed. The pedal should rest on the foot plate when the pump is stroked in the full forward position. To make an adjustment, disconnect the ball joint from the pedal arm and loosen the jam nut (See Figure 6). Place the foot control pedal forward against the foot rest and adjust the ball joint on the rod until the stud aligns with the hole in the arm. Bolt the ball joint to the arm and tighten the jam nut.

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.
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).
Use of Tension Gauge sgb007
Figure 8. Blade Drive Belt Tension Check
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.
11
Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mounting bolts to the top or to the bottom of the spindle shaft.
All blades should be positioned equally (See Figure 10).
The unit is shipped with one spacer on top of spindle and four underneath (See Figure 10).
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.
This adjustment does not affect blade pitch.

-NOTE-
For 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.
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.
SGB032
Figure 11. Cutter Deck Height Adjustment
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.

CUTTER BLADES
CAUTION:
Blades have a sharp cutting edge. Wear protective gloves or wrap blades with protective material when removing, sharpening and installing blades.
A. 3" Position - baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. (See Figure 15). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass.
Do Not Cut In
Angle Blade Back
B. 3-1/2" Position (factory setting, Advantage Deck) baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. (See
Figure 16). 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.

Do not sharpen beyond 1/3 of the width of the blade. (See
Figure 13).
-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 can occur. See your authorized Scag
Dealer for blade balance tools.
CUSTOM-CUT BAFFLE ADJUSTMENT
C. 4" Position (factory setting, Velocity Plus Deck) baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck . (See
Figure 17). 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:
1. Place the cutter deck in the transport position.
2. Remove the hardware securing the Custom-Cut
Baffle to the cutter deck. (See Figure 14).
-NOTE-
Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size.
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.

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 during the periods specified below. 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, hydraulic hoses and tires are warranted for ninety (90) days.
* Batteries are covered for ninety (90) days.
* Frame and structural components including oil reservoir and oil coolers are warranted for 2 years (Parts and
labor).
* Cutter decks are warranted against cracking for a period of three (3) years. (Parts and labor 1st and 2nd year;
Parts only 3rd year) The repair or replacement of the cutter deck will be at the option of Scag Power
Equipment. We reserve the right to request components for evaluation. This warranty does not cover any
mower that has been subject to misuse, neglect, negligence, accident, or that has been operated in any way
contrary to the operating instructions as specified in the Operator’s Manual.
* Engines and electric starters are covered by the engine manufacturer’s warranty period.
* Major drive system components are warranted for two (2) years by Scag Power Equipment. (Parts and labor)
(Two year warranty exclude fittings, hoses, drive belts). The repair or replacement of the hydraulic pump or
hydraulic motor will be at the option of Scag Power Equipment. 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.
* Electric clutches have a Limited Warranty for 2 year (Parts and labor).
* Cutter Spindle Assemblies have a Limited Warranty for three years (Parts and labor 1st and 2nd year;
Parts only 3rd year).
* Any Scag product used for rental purposes is covered by a 90 day warranty.
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, 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 obliga-
tion to modify any mower previously manufactured. All other implied warranties are limited in duration to the two (2) 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 two 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.
