Section 2

ROLL-OvER PROTECTION SYSTEM2.5

WARNING

Reduce speed when turning, operating on slopes, slick or wet surfaces. Allow extra distance to stop.

Stay off of slopes too steep for safe operation. To check a slope, attempt to back up it (with the cutter deck down). If the machine can not back up the slope without the wheels slipping, do not operate the machine on this slope. Under no circumstances should the machine be operated on slopes greater than 15 degrees.

DO NOT mow near drop-offs, ditches or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge caves in.

Any or all parts of the Roll-Over Protection System MUST NOT be removed. Failure to adhere to this guideline could result in injury or death.

FOLDABLE ROLL-OvER PROTECTION SYSTEM (IF EqUIPPED)

WARNING

Keep the roll bar in the raised and locked position and the seat belt securely fastened during operation. Failure to do so could cause serious injury or loss of life.

Lower the roll bar only when absolutely necessary.

WARNING

Operate the machine smoothly, no sudden turns, starts or stops on a slope.

NEvER tow on slopes. The weight of the towed equipment may cause loss of traction and loss of control.

DO NOT permit untrained personnel to operate the machine.

Be cautious when loading and unloading onto trailers or trucks.

Use only a full width ramp.

Ramp angle should be no more than 15 degrees.

Back up the ramp and drive down forward.

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. Do not mow on wet grass. Wet grass reduces traction and steering control.

There is no roll-over protection when the roll bar is in the down position.

Lower the roll bar only when absolutely necessary.

Raise the roll bar as soon as clearance permits.

DO NOT wear the seat belt when the roll bar is in the down position.

ALWAYS wear seat belt when roll bar is in the up position.

Section 4

INITIAL RUN-IN PROCEDURES4.3

Allow engine to warm before operating the mower.

FIRST DAY OF USE OR APPROxIMATELY 20 HOURS

Check all belts for proper alignment and wear at 2, 4 1. and 8 hours.

Change the engine oil and oil filter after the first 20 2. hours of operation. (See Section 7.4.)

Check hydraulic oil level in reservoir. (See Section 3.

7.3.) Check for loose hardware. Tighten as needed.

Check interlock system for proper operation. (See 5. Section 4.2.)

Check tire pressure. Adjust pressure if necessary. (See Section 7.10.)

STARTING THE ENGINE4.4

CAUTION

DO NOT USE STARTING FLUIDS. Use of starting ﬂuids in the air intake system may be potentially explosive or cause a “runaway” engine condition that could result in engine damage and/or personal injury.

Be sure the fuel shutoff valve, located behind the 1. operator's seat, is fully open. (See Section 7.5.)

Secure the ROPS in the upright and locked position. Sit in the operator’s seat, fasten seat belt and place 3.

the steering control levers in the neutral position.

GROUND TRAvEL AND STEERING4.5

- IMPORTANT -

If you are not familiar with the operation of a machine with lever steering and/or hydrostatic transmissions, the steering and ground speed operations should be learned and practiced in an open area, away from buildings, fences, or obstructions.

Learn the operation on flat ground before operating on slopes.

Start practicing with a slow engine speed and slow forward travel.

Learn to feather the steering controls to obtain a smooth operating action.

Practice operating the mower until you are comfortable with the controls before proceeding to mow.

FORWARD TRAvEL

To travel forward with the mower, disengage the parking brake, pull levers inward out of the neutral lock position and slowly push the steering control levers forward an equal distance. The further the steering control levers are pushed forward the greater the forward speed will be. To increase the speed, push the steering control levers further forward and to decrease the speed, pull the steering control levers back.

To stop the forward travel, pull the steering control levers back to the neutral position.

Engage the parking brake.4. Place the PTO switch in the disengaged position.5. If the engine is cold, choke the engine as needed.6. Move the engine throttle control to about half engine 7.

speed.

Turn the ignition key to the START position and release the key as soon as the engine starts. Do not hold the key in the START position for more than 15 seconds at a time. Allow at least 60 seconds between each cranking attempt to prevent overheating of the starter motor. Prolonged cranking can damage the starter motor and shorten battery life.

To steer the mower left while traveling forward, pull the left steering lever back. The further the lever is pulled back, the quicker the mower will turn left.

To steer the mower right while traveling forward, pull the right steering control lever back. The further the lever is pulled back, the quicker the mower will turn right.

- NOTe -

Smooth operation of the steering levers will produce smooth mower operation. While learning the operation of the steering controls, keep the travel speed low.

Section 4

390S0138

PULL UP TO ENGAGE

PUSH DOWN TO DISENGAGE

- IMPORTANT -

Do not travel forward over a curb. The mower will hang up on the curb. Raise the deck and travel backwards over the curb at a 45 degree angle. (See Section 4.1, items 13 - 15, on page 14 for cutter deck raising descriptions.)

REvERSE TRAvEL

CAUTION

Disengage power to the mower before backing up. Do not mow in reverse unless absolutely necessary and then only after observation of the entire area behind the mower.

CAUTION

To stop the reverse travel, allow the steering control levers to return to the neutral position. If the mower is to be parked, place the handles in the neutral lock position and engage the parking brake.

ENGAGING THE DECK DRIvE (CUTTER 4.6

BLADES)

Set the throttle at about 3/4 speed. Do not attempt to 1. engage the deck drive at high speed as this shortens the electric clutch life — use only moderate engine speed when engaging the deck drive.

Engage the deck drive by pulling out on the yellow 2. switch, located on the instrument panel, to the engage position. See Figure 4-3.

Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.

To travel in reverse, pull levers inward out of the neutral lock position and pull both handles back. Keep the travel speed low while traveling in reverse.

- NOTe -

The mower may not travel straight in reverse. Slight adjustments may need to be made using the steering controls.

To steer left while traveling in reverse, allow the left steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn left.

To steer right while traveling in reverse, allow the right steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn right.

Cutter engage SwitchFigure 4-3.

- 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.

To disengage the deck drive, push the switch in to 3. the disengage position.

Always operate the engine at full throttle to properly 4. maintain cutting speed. If the engine starts to lug down, reduce the forward speed and allow the engine to operate at maximum RPM.

Section 4

HILLSIDE OPERATION4.7

WARNING

This mower has been designed for good traction 1. 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. The Roll-Over Protection System is standard equipment for this machine. See Section 2.5, page 6 of this manual for further details.

AFTER OPERATION4.9

Wash the entire mower after each use. Do not 1. use high pressure spray or direct the spray onto electrical components.

- 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.

Keep the entire mower clean to inhibit serious heat

2. damage to the engine or hydraulic oil circuit.

Check the drive belts for proper alignment and any 3. signs of wear. Correct and adjust if necessary.

DANGER

To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

To prevent tipping or loss of control, do not start or 2. stop suddenly, avoid unnecessary turns and travel at reduced speed. If tires loose traction, disengage blades and proceed slowly off the slope.

Avoid sudden starts when mowing uphill. Sudden 3. starts may cause the machine to tip backwards.

Loss of traction may occur when traveling down hill.

4. Weight transfers to the front of the machine and may cause the drive wheels to slip causing loss of braking or steering.

Keep tires properly inflated.

PARKING THE MOWER4.8

Park the machine on a flat, level surface only. Do not 1. park the machine on an incline.

Place the steering control levers in the neutral

2. position.

Disengage the cutter blades.3. Slow the engine to idle speed.4. Engage the parking brake.5.

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.

Check the tire pressure. Adjust pressure if 5. necessary.

REMOvING CLOGGED MATERIAL4.10

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.

Turn the ignition key to the OFF position and remove 6. the key.

To “free-wheel” or move the mower around without the engine running, rotate the dump valve levers counterclockwise. See Figure 4-4. Disengage the parking brake and move the mower by hand. When the machine is in the desired position, engage the parking brake and rotate the levers clockwise until they stop. The dump valve levers must be returned to the DRIVE position and torqued to 10 lb-ft to drive the mower.

Section 4

Keep mower and discharge chute clean. When mowing wet or tall grass, mow the grass twice. 5.

Raise the mower to the highest setting for the first pass and then make a second pass to the desired height.

Use a slow travel speed for trimming purposes.6. Operate the engine at full throttle for best cutting. 7.

Mowing with a lower RPM causes the mower to tear the grass. The engine is designed to be operated at full speed.

Use the alternate stripe pattern for best lawn 8. appearance. Vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass.

ADJUSTING CUTTING HEIGHT4.13

The mower deck can be adjusted from a height of 1.0 inch to 6.0 inches at 1/4-inch intervals. To adjust the cutting height:

DO NOT operate without Discharge Chute, Mulching Kit, or entire Grass Catcher properly installed.

Dump Valve ControlFigure 4-4.

RECOMMENDATIONS FOR MOWING4.12

Do not mow with dull blades. A dull blade will tear 1. grass, resulting in poor lawn appearance and reduced mowing power.

WARNING

The discharge chute must not be removed and 2. 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.

WARNING

DO NOT adjust the cutting height with the mower blades rotating. Disengage the power to the cutter blades and then adjust cutting height.

Disengage the power to the cutter blades. Push the cutting height adjustment foot pedal all 2.

TRACKING ADJUSTMENT

CAUTION

Stop the engine and remove the key from the ignition before making any adjustments. Wait for all moving parts to come to a complete stop before beginning work.

- NOTe -

If after making the adjustment as outlined in step 1A, the machine creeps forward or backward, perform the neutral adjustment. See Neutral Adjustment on page 25.

If at full speed the mower pulls left, it is an indication that the right wheel is turning faster than the left wheel. To adjust this condition, proceed as follows:

A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the RH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the RH pump less, slowing down the RH wheel. See Figure 6-3.

- NOTe -

If after making the adjustment as outlined in step 2A, the machine creeps forward or backward, perform the neutral adjustment. See Neutral Adjustment on page 25.

CAUTION

The engine and drive unit can get hot during operation causing burn injuries. Allow engine and drive components to cool before making any adjustments.

- NOTe -

Before proceeding with this adjustment, be sure that the caster wheels turn plus pivot freely and that the tire pressure in the drive wheels is correct. If the tire pressure is not correct, the machine will pull to the side with the lower pressure.

If at full speed the mower pulls right, it is an

1. indication that the left wheel is turning faster than the right wheel. To adjust this condition, proceed as follows:

A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the LH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the LH pump less, slowing down the LH wheel. See Figure 6-4.

CUTTER DECK ADJUSTMENTS6.6

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.

CUTTER DECK LEvEL

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:

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.

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 hanging chains. 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 hanging chains. 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:

Loosen the jam nut on both adjusting rods. See Figure 6-6.

On the front LH side of the cutter deck locate the 1. cutter deck level adjusting bracket. See Figure 6-5.

CUSTOM-CUT BAFFLE ADJUSTMENT6.7

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) (early models), or seven (7) (current production) different positions for optimum performance.

3-POSITION CUSTOM-CUT BAFFLE ADJUSTMENT - EARLY MODELS

A. 3" Position - (See Figure 6-9). Baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. In this position the Velocity-Plus cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass.

Section 6

B. 3-1/2" Position - (See Figure 6-9). Baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. Can be used for general purpose cutting. Placing the Custom-Cut Baffle in the 3-1/2" position gives a good mix of cutting performance in all types of grass.

C. 4" Position (factory setting) - (See Figure 6-9). Baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck. Placing the baffle in the 4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout".

ELECTRIC CLUTCH ADJUSTMENT6.8

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.

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.

Clutch Air Gap AdjustmentFigure 6-1.

Locate the inspection windows on the clutch.1. Place a 0.015 feeler gauge in the slot between the 2.

rotor and the armature. Tighten or loosen the adjusting bolt as needed to 3.

acheive the 0.015 inch airgap. See Figure 6-4. Perform this operation at all three inspection windows.

Clutch Air Gap AdjustmentFigure 6-1.

This adjustment should be done every 500 hours of operation or annually, whichever comes first. In cases where the machine is heavily used, airgap settings should be checked more often.

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.

BATTERY7.7

WARNING

Lead-acid batteries produce flammable and explosive gases. To avoid personal injury when checking, testing or charging batteries, DO NOT use smoking materials near batteries. Keep arcs, sparks and ﬂames away from batteries. Provide proper ventilation and wear safety glasses.

WARNING

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to cause cancer and reproductive harm. Wash hands after handling.

A. CHARGING THE BATTERY

Refer to the battery charger’s manual for specific instructions.

Under normal conditions the engine’s alternator will have no problem keeping a charge on the battery. If the battery has been completely discharged for a long period of time, the alternator may not be able to recharge the battery, and a battery charger will be required.

DO NOT charge a frozen battery. It may explode and cause injury. Let the battery warm before attaching a charger.

Whenever possible, remove the battery from the mower before charging and make sure the electrolyte covers the plates in all cells.

WARNING

BATTERIES PRODUCE ExPLOSIvE GASES. Charge the battery in a well ventilated space so gases produced while charging can dissipate.

WARNING

Electric storage battery ﬂuid contains sulfuric acid which is POISON and can cause SEvERE CHEMICAL BURNS. Avoid contact of ﬂuid with eyes, skin, or clothing. Use proper protective gear when handling batteries. DO NOT tip any battery beyond 45° angle in any direction. If ﬂuid contact does occur, follow ﬁrst aid suggestions below.

BATTERY ELECTROLYTE FIRST AID

External Contact — Flush with water.

Eyes — Flush with water for at least 15 minutes and get medical attention immediately.

Internal — Drink large quantities of water. Follow with Milk Of Magnesia, beaten egg, or vegetable oil. Get medical attention immediately. In case of internal contact, DO NOT give ﬂuids that would induce vomiting.

Charging rates between 3 and 50 amperes are satisfactory if excessive gassing or spewing of electrolyte does not occur or the battery does not feel excessively hot (over 125°F). If spewing or gassing occurs or the temperature exceeds 125°F, the charging rate must be reduced or temporarily stopped to permit cooling.

B. JUMP STARTING

The booster battery must be a 12 volt type. If a 1. vehicle is used for jump starting, it must have a negative ground system.

CUTTER BLADES7.9

A. BLADE INSPECTION

Remove the ignition key before servicing the blades.1. Raise the mower deck to the highest position. Place 2.

the lanyard pin in the highest cutting height position to prevent the cutter deck from falling.

B. BLADE SHARPENING

- NOTe -

If possible, use a file to sharpen the blade. Using a wheel grinder may burn the blade.

- NOTe -

DO NOT sharpen the blades beyond 1/3 of the width of the blade. See Figure 7-7.

Sharpen the cutting edge at the same bevel as the original. See Figure 7-7. Sharpen only the top of the cutting edge to maintain sharpness.

WARNING

Always wear proper hand and eye protection when working with cutter blades.

Check the cutter blades for straightness. If the cutter 3. blades appear bent, they will need to be replaced.

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.

If a blade cutting edge is dull or nicked, it should be 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.

Blade SharpeningFigure 7-7.

Check the balance of the blade. If the blades are out 2. of balance, vibration and premature wear can occur. See your authorized Scag dealer for blade balancing or special tools, if you choose to balance your own blades.
