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.  
BEFORE OPERATING  
1. NEVER allow children to operate this riding mower.  
Do not allow adults to operate this machine without  
proper instructions.  
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. DO NOT mow when children and/or others are  
present. Keep children out of the mowing area and in  
the watchful care of a responsible adult other than the  
operator. Be alert and turn machine off if a child  
enters the area.  
I. If fuel is spilled on clothing, change clothing  
immediately.  
3. The owner/user can prevent and is responsible for  
accidents or injuries occuring to themselves, other  
people or property.  
J. Replace gas cap and tighten securely.  
8. If the operator(s) or mechanic(s) cannot read English  
or Spanish, it is the owner's responsibility to explain  
this material to them.  
4. Clear the area to be mowed of objects that could be  
picked up and thrown by the cutter blades.  
5. DO NOT carry passengers.  
9. DO NOT wear loose fitting clothing that could get  
tangled in moving parts. Do not operate the machine  
wearing shorts; always wear adequate protective  
clothing including long pants. Wearing safety glasses,  
safety shoes and a helmet is advisable and is required  
by some local ordinances and insurance regulations.  
6. DO NOT operate the machine under the influence of  
alcohol or drugs.  
7. Fill the fuel tank with clean, fresh gasoline, with a  
minimum octane rating of 87. To avoid personal  
injury or property damage, use extreme care in  
handling gasoline. Gasoline is extremely flammable  
and the vapors are explosive.  
10. Operator hearing protection is recommended,  
particularly for continuous operation of the mower.  
Wear suitable hearing protection. Prolonged  
exposure to loud noise can cause hearing impairment  
or loss.  
A. Extinguish all cigarettes, cigars, pipes and other  
sources of ignition.  
11. Keep the machine and attachments in good operating  
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.  
B. Use only an approved gasoline container.  
C. Never remove the gas cap or add fuel with the  
engine running. Allow the engine to cool before  
fueling.  
12. Be sure the safety switches are functioning correctly.  
D. Never fuel the machine indoors or in an enclosed  
trailer.  
13. USE ONLY SCAG APPROVED  
ATTACHMENTS AND ACCESSORIES.  
Attachments and accessories manufactured by  
companies other than Scag Power Equipment are not  
approved for use on this machine. Scag approved  
attachments and accessories:  
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  
beforefilling.

-NOTE-  
MOWER OPERATION  
When the PTO is engaged or (possibly) disen-  
gaged, 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.  
1. Readandunderstandthesafetyinstructions  
before attempting to operate this machine.  
2. Before starting the engine:  
* Check the oil level in the engine and the  
hydraulicreservoir.  
* Fill the fuel tank with clean, fresh, lead-free  
gasoline.  
* Open the fuel valve on the bottom of the  
fueltank.

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

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.  
CUTTER BLADES  
CAUTION:  
Blades have a sharp cutting edge. Wear protective  
gloves or wrap blades with protective material when  
removing, sharpening and installing blades.  
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.

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".

Figure 13. Blade Sharpening  
Donotsharpenbeyond1/3ofthewidthoftheblade. (See  
Figure 13).  
To adjust the Custom-Cut Baffle height:  
-NOTE-  
1. Place the cutter deck in the transport position.  
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 prema-  
ture wear can occur. See your authorized Scag  
Dealer for blade balance tools.  
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.  
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.

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

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

nience. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limita-  
tion 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.
