4.6 ENGAGING THE DECk DRIvE (CUTTER  
BLADES)  
4.7 HILLSIDE OPERATION  
1. Set the throttle at about 3/4 speed. Do not attempt to  
engage the deck drive at high speed as this shortens  
the electric clutch life — use only moderate engine  
speed when engaging the deck drive.  
WARNING  
DO NOT operate on steep slopes. ALWAYS  
FOLLOW OSHA APPROvED OPERATION.  
2. Engage the deck drive by pulling out on the yellow  
switch, located on the instrument panel, to the  
engage position. See Figure 4-2.  
1. This mower has been designed for good traction and  
stability under normal mowing conditions. However,  
caution must be used when traveling on slopes,  
especially when the grass is wet. Wet grass reduces  
traction and steering control.  
2. To prevent tipping or loss of control, do not start or  
stop suddenly, avoid unnecessary turns and travel  
at reduced speed. If tires lose traction, disengage  
blades and proceed slowly off the slope.  
PULL UP TO ENGAGE  
3. Avoid sudden starts when mowing on slopes.  
PUSH DOWN TO DISENGAGE  
4. Travel across the slope whenever possible. Never up  
and down the slope.  
390S0138  
Figure 4-2. Cutter Engage Switch  
- NOTE -  
5. Keep tires properly inflated.  
4.8 PARkING THE MOWER  
1. Park the machine on a flat, level surface only. Do not  
park the machine on an incline.  
A squealing noise may be heard when engaging  
or disengaging the deck drive. It is caused by the  
electric clutch plates meshing as the mower comes  
up to speed. This is normal.  
2. Disengage the cutter blades.  
3. Lock the neutral latches and shift the transmission  
into the neutral position.  
3. To disengage the deck drive, push the switch in to  
the disengage position.  
4. Slow the engine to idle speed.  
4. Always operate the engine at full throttle to properly  
maintain cutting speed. If the engine starts to lug  
down, reduce the forward speed and allow the  
engine to operate at maximum RPM.  
5. Turn the ignition key to the OFF position and remove  
the key.

4.9 AFTER OPERATION  
4.11 MOvING MOWER WITH ENGINE  
STOPPED  
1. Wash the entire mower after each use. Do not  
use high pressure spray or direct the spray onto  
electrical components.  
To free-wheel” or move the mower around without the  
engine running, engage the neutral latches, shift the  
transmission to neutral and move the mower by hand.  
- IMPORTANT -  
Do not wash a hot or running engine. Cold water  
will damage the engine. Use compressed air to  
clean the engine if it is hot.  
4.12 RECOMMENDATIONS FOR MOWING  
1. Do not mow with dull blades. A dull blade will tear  
grass, resulting in poor lawn appearance and  
reduced mowing power.  
2. Keep the entire mower clean to inhibit serious heat  
damage to the engine or hydraulic oil circuit.  
3. Check the drive belts for proper alignment and any  
signs of wear. Correct and adjust if necessary.  
WARNING  
DO NOT operate without Discharge Chute,  
Mulching kit, or entire Grass Catcher properly  
installed.  
DANGER  
To avoid injury from burns, allow the mower  
to cool before removing the fuel tank cap and  
refueling.  
2. The discharge chute must not be removed and  
must be kept in the lowest position to deflect grass  
clippings and thrown objects downward. Direct the  
side discharge away from sidewalks or streets to  
minimize cleanup of clippings. When mowing close  
to obstacles, direct the discharge away from the  
obstacles to reduce the chance of property damage  
by thrown objects.  
4. After the mower has cooled down, fill the fuel tank  
with fresh, clean fuel at the end of every day of  
operation. See Engine Owner's Manual for proper  
octane requirements.  
5. Check the tire pressure. Adjust pressure if  
necessary.  
3. Cut grass when it is dry and not too tall. Do not cut  
grass too short (cut off 1/3 or less of existing grass  
for best appearance). Mow frequently.  
4.10 REMOvING CLOGGED MATERIAL  
4. Keep mower and discharge chute clean.  
5. When mowing wet or tall grass, mow the grass twice.  
Raise the mower to the highest setting for the first  
pass and then make a second pass to the desired  
height.  
DANGER  
ROTATING BLADES  
6. Use a slow travel speed for trimming purposes.  
NEvER PUTYOUR HANDS INTOTHE DISCHARGE  
CHUTE FOR ANY REASON!  
7. Operate the engine at full throttle for best cutting.  
Mowing with a lower RPM causes the mower to tear  
the grass. The engine is designed to be operated at  
full speed.  
Shut off the engine and remove the key and  
only then use a stick or similar object to remove  
material if clogging has occurred.  
8. Use the alternate stripe pattern for best lawn  
appearance. Vary the direction of the stripe each  
time the grass is mowed to avoid wear patterns in  
the grass.  
1. If the discharge chute becomes clogged, shut off  
the engine and remove the ignition key. Using a stick  
or similar item, dislodge the clogged material. Then  
resume normal mowing.

ADJUSTMENTS  
6.1 DRIvE CONTROL ADJUSTMENTS  
6.3 BELT ADJUSTMENT  
1. Adjust the steering control rods so that there is  
approximately 3/4" clearance from the bottom of the  
rod to the bottom of the neutral latch slot when in the  
drive position. See Figure 6-1.  
WARNING  
Before removing any guards, shut the engine off  
and remove the ignition key.  
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.  
All drive belts are spring loaded and self-tensioning,  
however after the first 2, 4, 8 and 10 hours of operation,  
the belts should be checked for proper alignment and wear.  
Thereafter, check the belts after every 40 hours of operation  
or weekly, whichever occurs first.

6.2 THROTTLE CONTROL AND CHOkE  
ADJUSTMENTS  
CUTTER DECk LEvEL  
These adjustments must be performed by your Scag dealer  
to ensure proper and efficient running of the engine.Should  
either need adjustment, contact your authorized Scag  
service center.  
The cutter deck should be level from side-to-side for  
proper cutting performance. To check for level, be sure  
that the mower is on a flat, level surface, the tires are  
properly inflated and the cutter deck is set at the most  
common cutting height that you will use. On the RH side  
of the machine, check the distance from the top of the  
cutter deck to the floor. Next check the distance from the  
top of the cutter deck to the floor on the LH side of the  
machine. Both measurements should be the same. If the  
two measurements are different, the cutter deck level must  
be adjusted as follows:

R
Section 6  
1. On the front of the cutter deck locate the cutter deck  
adjustment slots. See Figure 6-2.  
Check the distance from the top of the cutter deck to the  
floor at the rear RH side of the cutter deck directly behind  
the cutter deck height adjustment bracket. Next check  
the distance from the top of the cutter deck to the floor at  
the front RH side of the cutter deck directly in front of the  
cutter deck height adjustment bracket. The measurement  
at the front of the cutter deck should be the same as the  
rear of the deck.Make these measurements at the LH side  
of the cutter deck also. If the measurement at the front of  
the deck is not the same, the cutter deck pitch must be  
adjusted as follows:  
1. Loosen the two (2) elastic stop nuts. Adjust the cutter  
deck up or down in the adjustment slot to adjust until  
the distance from the top of the cutter deck to the  
floor is the same as the measurement on both sides  
of the machine.  
ADJUSTMENT SLOT  
2. Tighten the two (2) elastic stop nuts to secure the  
cutter deck in the proper position.  
6.6 ELECTRIC CLUTCH ADJUSTMENT  
The electric clutch serves two functions in the operation of  
the mower. In addition to starting and stopping the power  
flow to the cutter blades, the clutch also acts as a brake to  
assist in stopping blade rotation when the PTO is switched  
off or the operator presence circuit is interrupted.  
ADJUSTMENT SLOT  
When the clutch is disengaged, the air gap between the  
armature and rotor must be adjusted to fifteen thousandths  
of an inch, 0.015, for proper operation. The airgap  
adjustment is made at three bolts on the clutch.There are  
three inspection windows, one next to each adjusting bolt.  
See Figure 6-3.  
Figure 6-2. Cutter Deck Adjustment Slots  
2. Loosen the two (2) elastic stop nuts. Adjust the cutter  
deck up or down in the adjustment slot to adjust until  
the distance from the top of the cutter deck to the  
floor is the same as the measurement on both sides  
of the machine.  
INSPECTION WINDOW (x3)  
3. Tighten the two (2) elastic stop nuts to secure the  
cutter deck in the proper position.  
CUTTER DECk PITCH  
The pitch of the cutter deck should be equal between  
the front and rear of the cutter deck for proper cutting  
performance. To check for proper deck pitch, be sure  
that the mower is on a flat, level surface and the tires are  
properly inflated.

Keep the blades sharp.Cutting with dull blades not  
only yields a poor mowing job, but slows the cutting  
speed of the mower and causes extra wear on the  
engine and the blade drive by pulling hard.  
B. BLADE SHARPENING  
- NOTE -  
Be sure that the blade is installed with the lift wing  
towards the top of the cutter deck.  
- NOTE -  
If possible, use a file to sharpen the blade. Using  
a wheel grinder may burn the blade.  
4. Install the cutter blade on to the cutter spindle shaft.  
Secure the blades from rotating and torque to  
75 ft/lbs. See Figure 7-4.  
- NOTE -  
DO NOT sharpen the blades beyond 1/3 of the  
width of the blade. See Figure 7-3.  
1. Sharpen the cutting edge at the same bevel as the  
original. See Figure 7-3. Sharpen only the top of the  
cutting edge to maintain sharpness.
