4.7 HILLSIDE OPERATION
WARNING
DO NOT operate on steep slopes. ALWAYS
FOLLOW OSHA APPROvED OPERATION.
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.
3. Avoid sudden starts when mowing on slopes.
4. Travel across the slope whenever possible. Never up and down the slope.
5. Keep tires properly inflated.
Figure 4-2. Cutter Engage Switch
- NOTE -
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.
3. To disengage the deck drive, push the switch in to the disengage position.
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.
4.8 PARkING THE MOWER
1. Park the machine on a flat, level surface only. Do not park the machine on an incline.
2. Disengage the cutter blades.
3. Lock the neutral latches and shift the transmission into the neutral position.
4. Slow the engine to idle speed.
5. Turn the ignition key to the OFF position and remove the key.

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.
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.
4.11 MOvING MOWER WITH ENGINE
STOPPED
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.
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.
DANGER
To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.
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.
4.10 REMOvING CLOGGED MATERIAL
DANGER
ROTATING BLADES
NEvER PUT YOUR HANDS INTO THE DISCHARGE
CHUTE FOR ANY REASON!
Shut off the engine and remove the key and only then use a stick or similar object to remove material if clogging has occurred.
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.
WARNING
DO NOT operate without Discharge Chute,
Mulching kit, or entire Grass Catcher properly installed.
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.
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. 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.
6. Use a slow travel speed for trimming purposes.
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.
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.

Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be made, the following procedures will aid in obtaining the proper cutter deck adjustment.
- NOTE -
Before proceeding with the cutter deck adjustments, be sure that all tires are properly inflated.
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
19
R
Section 6
1. On the front of the cutter deck locate the cutter deck adjustment slots. See Figure 6-2.
ADJUSTMENT SLOT
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.
2. Tighten the two (2) elastic stop nuts to secure the cutter deck in the proper position.
6.6 ELECTRIC CLUTCH ADJUSTMENT
ADJUSTMENT SLOT
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.
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.
3. Tighten the two (2) elastic stop nuts to secure the cutter deck in the proper position.
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.
INSPECTION WINDOW (x3)
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.
Figure 6-3. Clutch Air Gap Adjustment
1. Locate the inspection windows on the clutch.
2. Place a 0.015 feeler gauge in the slot between the rotor and the armature. See Figure 6-4.
20
Section 6
INSERT 0.015 FEELER GAUGE HERE
R
If the air gap is too narrow, the clutch armature may drag when disengaged, resulting in premature failure.
If the air gap is too wide, the clutch may be slow to engage as the magnet must pull the armature in from a greater distance.
Figure 6-4. Clutch Air Gap Adjustment
3. Tighten or loosen the adjusting bolt as needed to acheive the 0.015 inch airgap. See Figure 6-5.
Perform this operation at all three inspection windows.
ADJUSTMENT NUTS
ADJUSTMENT NUTS

7.5 ENGINE AIR CLEANER
WARNING
Always wear proper hand and eye protection when working with cutter blades.
A. CLEANING AND/OR REPLACING AIR
CLEANER ELEMENT
For any air cleaner, the operating environment dictates the air cleaner service periods. Inspect and clean the air cleaner element after every 100 hours of operation or biweekly, whichever occurs first and replace the element if required.
3. Check the cutter blades for straightness. If the cutter blades appear bent, they will need to be replaced.
- NOTE -
In extremely dusty conditions it may be necessary to check the element once or twice daily to prevent engine damage.
WARNING
Do not attempt to straighten a bent blade, and never weld a broken or cracked blade. Always replace it with a new blade to assure safety.
4. If a blade cutting edge is dull or nicked, it should be
1. Release the two latches securing the air cleaner cover to the air cleaner assembly and remove the cover. Set aside.

Section 7 sharpened. Remove the blades for sharpening. See
"Blade Replacement."
- NOTE -
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 -
If possible, use a file to sharpen the blade. Using a wheel grinder may burn the blade.
2. Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height position to prevent the cutter deck from falling.
3. Secure the cutter blades to prevent them from rotating, (use the optional Blade Buddy tool P/N
9212, to assist in securing the cutter blades), remove the blade attaching bolt. Remove the cutter blade, bolt, lockwasher and flatwasher from the spindle shaft. See Figure 7-4.
- NOTE -
Be sure that the blade is installed with the lift wing towards the top of the cutter deck.
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.
