4.2 SAFETY INTERLOCK SYSTEM
This mower is equipped with a safety system that prevents the engine from starting unless the mower blade brake is disengaged and parking brake is engaged. The system also shuts the engine off if the operator's left foot is raised from the interlock pedal with the mower and parking brakes disengaged.
WARNING:
Never operate the mower with the interlock system disconnected or malfunctioning. Do not disconnect or bypass any switch; injury to yourself and others or property damage could result.
If the safety interlock system is malfunctioning or if you want to ensure that it is working properly, perform the tests in Table 4-1. Stop the test and have the system inspected and repaired if:
4.3 INITIAL RUN-IN PROCEDURES (First Day of Use or Approximately 10 Hours)
1. Check all belts for proper tension at 2, 4 and 8 hours; adjust as needed.
2. Check the neutral adjustment. If necessary, adjust the linkage so that the mower does not move when forward and reverse pedal is in neutral (See Adjustments in Section 6).
3. Check the tires for proper inflation (See Section 7-2).
4. Check for loose hardware. Tighten as needed.
5. Perform Interlock Tests in Table 4-1.
6. Apply lubricant to all machine grease fittings. See Lubrication Chart in Section 7.2.

4.4 DIESEL ENGINE BREAK-IN
The proper break-in of a new diesel engine can make a difference in the performance and life of the engine. Perform the following break-in procedure during the first 50 hours of operation:
1. A new engine should be operated with as near full load as possible. However, the engine must be allowed to reach an operating temperature before operating at full load conditions.
2. The engine oil should be checked twice daily. Higher than normal oil consumption is not uncommon during the initial break-in period.
3. Change the oil and filter element after the first 40 hours of operation.
4. Check all engine belts for proper tension after the first 10 hours of operation and adjust, if necessary. Refer to Adjustments in Section 6.
4. Turn the ignition key switch to the PREHEAT position until the indicator light for the glow plug glows bright red. The colder the temperature, the longer it will take to energize the glow plug. This step is not necessary when starting a warm engine.
5. Turn the ignition key switch to 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 inhibit overheating the starter motor. Prolonged cranking can damage the starter motor and shorten battery life.
6. Allow engine to warm to operating temperature.
4.6 OPERATOR COMFORT ADJUSTMENTS
Two adjustments can be made to make your mowing job comfortable. The steering handle can be adjusted up or down and the seat can be adjusted forward or back.
5. During the break-in period, check and tighten all engine hardware.
4.5 STARTING THE DIESEL ENGINE
CAUTION:
DO NOT USE STARTING FLUIDS. Use of starting fluids in the air intake system may be potentially explosive or cause “Runaway” engine condition that could result in engine damage and/or personal injury.
1. Be sure the fuel shut-off valve is completely open. The valve is located in the fuel line between the fuel tank and electric fuel pump (See Section 7).
2. Sit in the operators seat and depress the interlock foot pedal with your left foot. Make sure the parking brake and mower blade brake are engaged.
A. Adjusting Steering Handle Height
1. Remove the hardware securing the handle to the steering shaft. Two sets of holes are available to adjust the handle height.

Figure 4-5 Seat Adjustment
4.7 ADJUSTING GROUND SPEED AND
DIRECTION
-NOTE-
If you are not familiar with the operation of the hydrostatic drive, practice turning and ma­neuvering with the foot controls before engag­ing the blades. Learn the operation in an open area away from buildings, fences, or obstruc­tions. Learn the operation on a flat ground before operating on slopes. Start maneuver­ing with SLOW engine speed until you are fa­miliar with all operating characteristics. Prac­tice maneuvering the mower until you can make it go exactly where you intend.
1. To travel forward, depress the right foot pedal at the toe. (See Figure 4-6). The further the pedal is de­pressed the faster the mower will travel forward.
Figure 4-6 Forward - Depress Toe End of Pedal
-NOTE-
Before shifting from forward to reverse, or re­verse to forward, come to complete stop then shift the foot pedal to the desired direction.
2. To travel backwards (reverse), depress the right foot pedal at the heel (See Figure 4-7). The further the pedal is depressed the faster the mower will travel backwards. Use slower traveling speed when traveling backwards and observe the area behind you before moving.
-NOTE-
If the mower is driven on public roads, it must comply with state and local ordinances as well as SAE J137 and/or ASME S279 requirements. Contact your local authorities for regulations and equipment requirements.
-NOTE-
The left operator foot pedal must be depressed before operation.
Figure 4-7 Backward (Reverse) Operation- Depress
Heel End of Pedal
12
Section 4
3. Check that all systems function correctly.
4. When traveling, the throttle control can be adjusted to increase or decrease travel speed.
5. Reduce speed when turning around trees, shrubs, etc.
IMPORTANT:
Avoid high-speed turns on all surfaces. Tires can slip on grass and can wear rapidly on concrete and asphalt.
6. When going over curbs, first activate the mower deck lift switch to fully raise the deck to clear the curb. Go FORWARD over the curb.
4.8 ENGAGING THE MOWER
1. Set engine throttle about 1/2 speed. Do not attempt to engage the blade at high engine speed as this
shortens the electric clutch life  use only moderate engine speed when engaging the blades.
3. Always operate the engine at full throttle to properly maintain cutting speeds. If the engine starts to lug down, reduce the forward speed to allow the engine to operate at maximum RPM.
4.9 HILLSIDE OPERATION
WARNING:
To minimize the possibility of overturning, the least dangerous method of operating on hills and terraces is to travel vertically up and down the slope, not horizontally along the slope. Avoid any unnecessary turns and travel at reduced speed.
1. The 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 limits traction and steering control.
2. Engage the mower blades by moving the blade brake lever down and to the right.
WARNING:
A safety interlock switch (left foot pedal) will cause the engine to stop if the blade brake is disengaged, and the left foot pedal is not depressed. The function of the switch should be checked by the operator raising his left foot and disengaging the blade brake; the engine should stop. If the switch is not working, it should be repaired or replaced before operating the mower. Do not disconnect the interlock safety switches because they are for the operators protec­tion.
-IMPORTANT-
Do not engage the mower blades when transporting the mower across drives, loose materials, etc.
2. To inhibit tipping or loss of control, do not start or stop suddenly, avoid unnecessary turns and travel at a reduced speed.
3. Keep tires properly inflated.
4. Always travel up or down the slope, whenever pos­sible; NEVER across the slope.
5. If the mower cannot climb the slope, the grade is too steep for safe operation. Do not make another attempt to climb the slope. Engage the blade brake to stop the blades and back down slowly.
13
Figure 4-8 Proper Operation on Slope
Section 4
-IMPORTANT-
If at all possible, do not engage the mower brake with engine running at high speed, since premature wear of the electric clutch will oc­cur. Lower speed to near idle then engage the brake.
CAUTION:
The blade brake stops the blades from rotating. If the blades do not stop, contact your Scag Dealer.
CAUTION:
Remove the key from the ignition switch when leaving the mower unattended to inhibit children and inexperienced operators from starting the engine.
Figure 4-9 Improper Operation on Slope
4.10 STOPPING
1. Slow engine speed to idle.
2. Place the right foot pedal in the center (neutral) position.
3. Engage the blade brake.
4. Engage the parking brake and turn ignition key to OFF.
4.1 1 AFTER OPERA TION
1. Park the mower on a flat and level surface and fully lower the cutting deck to the ground. Stop the engine and engage the parking and blade brakes. Remove the key from the ignition switch.
-IMPORTANT-
If the radiator dirt screen is not removed and cleaned after every use, the screen will be­come clogged with grass clippings, etc., block­ing the air flow through the radiator. This will cause a high engine operating tempera­ture that may cause damage to the engine.
2. Clean the radiator dirt screen. See Section 7 for radiator dirt screen removal and cleaning instructions..
3. Wash the entire mower after each use. Do not use high pressure spray or direct the spray onto electrical components.
14
Section 4
-IMPORTANT-
Do not wash a hot or running engine. Use compressed air to clean the engine and the radiator fins. Cold water will damage the engine and/or radiator.
4. Keep the entire mower clean to inhibit serious heat damage to the engine or hydraulic oil circuit.
5. Recheck the cutter drive belts for proper tension, alignment and any signs of rubbing. Correct and adjust as necessary.
6. Fill the fuel tank with fresh, clean fuel at the end of every day of operation.
7. Check the tire pressure. Inflate tires if necessary.
4.12 MOVING MOWER WITH THE ENGINE
STOPPED
To free-wheel or move the mower around without the engine running, rotate the dump valve handle (screw and nut) located on the side of the hydraulic pump to full open position. See Figure 4-10. Disengage the parking brake and move the mower by hand. The lever must be returned to the original position to operate the mower.
4.13 RECOMMENDATIONS FOR MOWING
1. Keep the mower deck and discharge chute clean.
2. Mow with sharp blades. A dull blade will tear grass, resulting in poor lawn appearance and takes extra power (slow mowing speed).
3. The discharge deflector must not be removed and must be kept in the lowest position to deflect grass clippings and thrown objects downward. Orient the side dis­charge away from sidewalks or street to minimize cleanup of clippings. When mowing close to obstacles, orient the discharge away from obstacles to reduce the chance of property damage by thrown objects.
4. Cut grass when it is dry and not too tall. Mow frequently and do not cut grass too short (cut off 1/3 or less of existing grass for best appearance).
5. Operate the engine at or near full throttle for best cutting. Mowing with a lower RPM causes the mower to not cut clean and tear the grass. The engine is designed to be operated at full speed.
6. Use slow travel speed for trimming purposes.
7. When mowing tall or wet grass, mow the grass twice. Raise the mower to the highest setting for the first pass and then make a second cutting pass to the desired height.

Figure 4-10 Dump Valve Handle
8. Be sure the mower is leveled properly for a smooth cut. See Section 7, Adjustments.
Open
9. Use alternate stripe mowing pattern for best appear­ance and vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass.
4.14 ADJUSTING CUTTING HEIGHT
The mower deck height switch on the instrument panel is used to adjust the cutting height of the deck. Do not adjust the cutting height while the mower is moving. Stop the mower, then activate the deck height switch to position the deck at the desired height. A gauge is located on the right front of the mower (See Figure 4-11) for use in selecting the proper cutting height.

ADJUSTMENTS
Section 6
6.1 P ARKING BRAKE ADJUSTMENT
WARNING:
Do not operate the mower if the parking brake is not operable. Possible severe injury could result.
The parking brake linkage should be adjusted whenever the parking brake lever is placed in the Engage position and the parking brake will not hold the mower from moving. A minor adjustment can be made at the control lever by loosening the jam nut shown in Figure 6-1 and turning the rod in a clockwise direction to tighten the linkage. Tighten the jam nut.
If this adjustment does not hold the mower from moving or no more thread is available on the rod, contact your Scag dealer before operating the mower.
6.2 FORW ARD/REVERSE NEUTRAL
ADJUSTMENT
The forward/reverse linkage should be adjusted whenever the mower will not stay stationary when the forward/reverse (right) foot pedal is placed in the neutral position.
1. Set the engine deck on jack stands so the wheels are free to rotate.
2. Block the caster wheels to prevent an accident should the unit fall off the jacks.
3. Start the engine and observe for drive wheel rotation.
If the wheels consistently rotate when the foot control is in neutral, go to step 4.
If the drive wheels intermittently rotate, i.e. the drive wheels sometimes rotate and sometimes do not when the foot pedal is not depressed, then check the neutral adjustment bolt for zero free play in the neutral control spring.

Section 6
-NOTE-
If you turn the nut too much, you will com­press the spring, making too much end play. Go to step 4.
4. If the drive wheels rotate in rearward travel direction, turn the adjustment bolt (Figure 6-1) clockwise until rotation stops. If the drive wheels rotate in the for­ward travel direction, turn the adjusting bolt counter­clockwise until rotation stops.
5. Check the adjustment of the right foot pedal for full forward speed. The bottom of the foot pedal should be 1/4 inch from the top of the foot plate (See Figure 6-1) when the pump is stroked in the full forward position.
To make an adjustment, loosen the jam nut at the pump control bellcrank (Figure 6-1). Depress the foot pedal and turn the control rod until 1/4 inch is obtained between the bottom of the foot pedal and the top of the foot plate. Tighten the jam nut.
6. Start the engine. The drive wheels should rotate only when the forward/reverse foot pedal is depressed.
6.3 THROTTLE CONTROL LINKAGE
ADJUSTMENT
Should the throttle control lever not stay in position after moving it to increase or decrease the engine speed, the throttle linkage must be tightened. Hold the lock nut (Figure 6-2) with a wrench while turning the bolt clockwise to tighten the throttle lever against the friction plate. Do not overtighten as the control lever will be hard to move.

6.4 CUTTER BRAKE LINKAGE
The cutter brake linkage is self-adjusting. If the brake will not hold the cutter blades from turning, consult your Scag dealer. Do not operate the mower if the cutter brake is not functioning properly.
6.5 FAN BELT ADJUSTMENT
1. Remove the pump belt guard to gain access to the fan drive idler bracket.
2. Loosen the two bolts (A and B, Figure 6-3). Using a 3/8 inch ratchet wrench installed in hole C, rotate the bracket until 1/2 inch deflection in the belt is observed using 10 pounds of pressure on the belt. See Engine Drive Belts, section 7.9 for checking method.
If the engine speed must be increased or decreased, consult your Scag dealer.

6.10 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.
6.11 CUTTER DECK ADJUSTMENTS
Due to many conditions that exist, it is difficult to suggest a setting that will work for every lawn. However, two adjustments should be made on the cutter deck to ensure proper grass cutting: DECK LEVEL AND PITCH.
-NOTE-
Before checking for proper cutter deck adjust­ments, check that all tires are inflated to the correct pressure.
DECK LEVEL is the adjustment to level the deck side-to­side. For proper blade cutting, the deck should be level. To check for level, place the mower on a flat, level surface. On the right side of the deck, measure from the ground to the bottom of the cutter deck (Figure 6-7). Then, take a measurement on the left side of the deck. Both measurements should be equal. If different, adjust the deck to level.
To level the deck, loosen the adjusting nut (Figure 6-8) and lift or lower the deck until the left side measurement equals the right side measurement. Tighten the adjusting nut.
Adjusting Nut
Figure 6-8 Leveling the Cutter Deck
PITCH is the adjustment to angle the blades from rear to front. For proper grass cutting, the blades should be angled forward. To check proper blade pitch, place the mower on a flat, level surface. Measure the distance from the ground to the rear of the mower deck ("X", Figure 6-9). Then, measure on both sides of the mower deck the distance from the ground to the front of the deck ("Y"). The front should be 1/4 inch lower than the rear. If not correct, adjust the pitch.
Figure 6-7 Measuring Height of Deck
= " Y "
Figure 6-9 Pitch Measurement
1. To adjust the pitch, loosen the jam nut on both adjusting rods (See Figure 6-10).

6.12 BLADE CUTTING HEIGHT
ADJUSTMENT
The blade cutting height is adjusted by actuating the deck height switch on the instrument panel. However, if the cutting height compared to what is shown on the cutting height gauge (See Figure 6-12) is in question, the cutting height should be checked. To check the cutting height, lift the discharge chute and measure from the ground to the cutting edge of the blade (See Figure 6-11). If the measurement is different from what is registered on the gauge, adjust the gauge rod to the proper setting.

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. 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, hoses and tires are warranted for 90 days. * Batteries are covered for 90 days. * Frame, deck, and structural components including oil reservoir, fittings, and oil cooler are
warranted for 1 year. * Engines and electric starters are covered by the manufacturers warranty period. * Drive system components are warranted for 1 year by the component manufacturer, in
conjunction with Scag Power Equipment. (Excluding fittings, hoses, cooling system, oil
reservoir, drive belts). * Electric clutch components are warranted for 1 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, or 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 obligation to modify any mower previously manufactured.
All other implied warranties are limited in duration to the one (1) year warranty period or ninety (90) days for mowers used for rental purpose.

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.

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.
