WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT IN SERIOUS INJURY OR
DEATH.
· Read this manual completely as well as other manuals that came with your
mower. · DO NOT operate on steep slopes. To check a slope, attempt to back up
it (with
the cutter deck down). If the machine can back up the slope without the wheels
slipping, reduce speed and use extreme caution. · Under no circumstances
should the machine be operated on slopes greater than 15 degrees. ALWAYS
FOLLOW OSHA APPROVED OPERATION. · Stay two cut widths away from slopes, drop
offs, ditches, water,retaining walls, avoid any slope exceeding 15 degrees,
and do not mow under trees on slopes with the roll bar down. · DO NOT mow on
wet grass. Wet grass reduces traction and steering control. · Keep all shields
in place, especially the grass discharge chute. · Before performing any
maintenance or service, stop the machine and remove the spark plug wire and
ignition key. · If a mechanism becomes clogged, stop the engine before
cleaning. · Keep hands, feet and clothing away from power-driven parts. · Keep
others off the mower (only one person at a time)

2.6 ROLL-OVER PROTECTION STRUCTURE
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.
1. To lower the roll bar, remove the hairpin cotter pins and remove the two
(2) lock pins. See Figure 2-3.
2. Lower the roll bar to the down position.
3. To raise the roll bar, lift the bar to the upright position.
4. Install the two (2) lock pins through the hole, secure with the two (2)
hairpin cotter pins. See Figure 2-3.
UPRIGHT AND LOCKED POSITION
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.
Any or all parts of the Roll-Over Protection Structure MUST NOT be removed.
Failure to adhere to this guideline could result in injury or death.
WARNING
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.
Operate the machine smoothly, no sudden turns, starts or stops.
Check the area carefully before mowing for proper overhead clearance (i.e.
branches, doorways, etc.).
DO NOT contact any overhead object with the roll bar.

The potential exposure of the seat belt to severe environmental conditions
make it crucial to inspect the seat belt system regularly.
It is recommended that the seat belt be inspected on a daily basis for signs
of damage. Any seat belt system that shows cuts, fraying, extreme or unusual
wear, significant discoloration due to UV exposure, dirt or stiffness,
abrasion to the seat belt webbing, or damage to the buckle, latch plate,
hardware or any other obvious problem should be replaced immediately.

Section 2
R
WARNING
Failure to properly inspect and maintain the seat belt can cause serious
injury or loss of life.
1. Check the full length of the seat belt webbing for cuts, wear, fraying,
dirt and stiffness. See Figure 2-4.
2. Check the seat belt webbing in areas exposed to ultra violet rays from the
sun or extreme dust or dirt. If the original color of the webbing in these
areas is extremely faded and/or is packed with dirt, the physical strength of
this webbing may have deteriorated. If this condition exists, replace the seat
belt system.
3. Check the buckle and latch for proper operation and determine if the latch
plate is excessively worn, deformed, or if the buckle is damaged or cracked.
See Figure 2-4.
4. Be sure to confirm that the seat belt recoil latch is functioning
properly.
INSPECT BUCKLE & LATCH
INSPECT WEBBING
Figure 2-4. Seat Belt Inspection
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. See Figure 2-5, page 11 to determine approximate slope.

roll over if a wheel goes over the edge or if the edge caves in.
Operate the machine smoothly, no sudden turns, starts or stops on a slope.
DO NOT lower the roll bar to mow under trees on slopes. If mowing under trees
is required, always use a walk-behind mower or string trimmer.
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. See Figure 2-5, page 11 to help
determine approximate slope.
Back up the ramp and drive down forward.

4.5 INITIAL RUN-IN PROCEDURES
FIRST DAY OF USE OR APPROXIMATELY 20 HOURS
1. Check all belts for proper alignment and wear at 2, 4 and 8 hours.
2. Change the engine oil and oil filter after the first 20 hours of
operation. (See Section 7.4.)
3. Check hydraulic oil level in reservoir. (See Section 7.3.)
4. Check for loose hardware. Tighten as needed. 5. Check interlock system for
proper operation. (See
Section 4.4.) 6. Check tire pressure. Adjust pressure if necessary.
(See Section 7.10.)
4.6 STARTING THE ENGINE
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.
1. Be sure the fuel shutoff valve, located behind the operator’s seat, is
completely open. (See Section 7.5.)
2. Secure the ROPS in the upright and locked position. 3. Sit in the
operator’s seat, fasten seat belt and place
the steering control levers in the neutral position. 4. Engage the parking
brake. 5. Place the PTO switch in the disengaged position. 6. If the engine is
cold, choke the engine as needed. 7. Move the engine throttle control to about
half engine
speed.
8. 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.
9. Allow engine to warm before operating the mower.
4.7 GROUND TRAVEL AND STEERING
– 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.
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.
21
R
– 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.
– 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 Figure 4-2 items 11-13 for cutter deck raising description.)
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.
Section 4
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.
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.
4.8 ENGAGING THE DECK DRIVE (CUTTER BLADES)
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.
2. Engage the deck drive by pulling out on the yellow switch, located on the
instrument panel, to the engage position. See Figure 4-6.
CAUTION
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.
PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE
Figure 4-6. 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.
22
Section 4 R
4.9 HILLSIDE OPERATION
WARNING
DO NOT operate on steep slopes. To check a slope, attempt to back up it (with
the cutter deck down). If the machine can back up the slope without the wheels
slipping, reduce speed and use extreme caution. Under no circumstances should
the machine be operated on slopes greater than 15 degrees. See Figure 2-5,
Page 11 to help determine approximate slope of area to be mowed. 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. The Roll-Over Protection System is standard equipment for this
machine. See Section 2.6 of this manual for further details.
2. To prevent tipping or loss of control, do not start or stop suddenly,
avoid unnecessary turns and travel at reduced speed. If tires loose traction,
disengage blades and proceed slowly off the slope.
3. Avoid sudden starts when mowing uphill. Sudden starts may cause the
machine to tip backwards.
4. Stay at least 2 cutting widths away from drop-offs, ditches, retaining
walls, water, avoid any slope exceeding 15-degrees, and do not mow under trees
on slopes with the roll bar down.
5. Loss of traction may occur when traveling down hill. Weight transfers to
the front of the machine and may cause the drive wheels to slip causing loss
of braking or steering.
6. Keep tires properly inflated. See Section 7.10.
5. Engage the parking brake. 6. Turn the ignition key to the OFF position and
remove
the key.
4.11 AFTER OPERATION
1. Wash the entire mower after each use. Do not 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.
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.
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. See Section 7.10.
4.10 PARKING THE MOWER
1. Park the machine on a flat, level surface only. Do not park the machine on
an incline.
2. Place the steering control levers in the neutral position.
3. Disengage the cutter blades.
4. Slow the engine to idle speed.
23
Section 4
R
4.12 REMOVING CLOGGED MATERIAL
DANGER
4.14 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.
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.
4.13 MOVING MOWER WITH ENGINE STOPPED
To “free-wheel” or move the mower around without the engine running, rotate
the dump valve counter-clockwise. See Figure 4-7. Disengage the parking brake
and move the mower by hand. When the machine is in the desired position,
engage the parking brake and rotate clockwise until they stop. The dump valves
must be returned to the DRIVE position and torqued to 10ft/lbs to drive the
mower.
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.

4.16 TOWING (OPTIONAL HITCH ACCESSORY)
1. NEVER allow children or others in or on towed equipment.
2. Tow only with a machine that has a hitch designed for towing. Do not
attach towed equipment except at the hitch point.
3. Follow manufacturer’s recommendations for weight limit for towed
equipment; 250/lbs. maximum towing weight.
4. NEVER tow on slopes. The weight of the towed equipment may cause loss of
traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Zero-turning with a trailer attached could cause damage to the trailer or
mower.

6.6 CUTTER DECK ADJUSTMENTS
CUTTER DECK PITCH
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:
1. If the cutter deck is lower on one side, loosen the elastic stop nuts
securing the deck level links on the front and rear of the lower side. See
Figure 6-5.
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:
1. Loosen the elastic stop nuts securing the deck level links on the front of
the cutter deck on both sides. See Figure 6-6 and 6-7.

Figure 6-7. Cutter Deck Pitch Adjustment
– NOTE –
To prevent the cutter deck from teetering, all four (4) cutter deck hanging
chains must have tension on them. If all four chains do not have tension on
them and the deck teeters, you must readjust the cutter deck as outlined in
the procedures above. All measurements should be taken from the top edge of
the deck as the deck has an uneven bottom edge.
Figure 6-8. Cutter Deck Height Adjustment
4. Turn the control rod (See Figure 6-8) until the measurement from the floor
to the cutter blade tip is at 4-1/2″. Tighten the jam nuts on the control rod.
– NOTE –
If an adjustment had to be made, be sure that the cutter deck can easily be
locked into the transport position.
CUTTER DECK HEIGHT
The cutter deck height adjustment is made to ensure that the cutter deck is
cutting at the height indicated on the cutting height index gauge. To check
for proper deck height, be sure that the mower is on a flat, level surface and
the tires are properly inflated.
1. Check the cutter deck cutting height by placing the lanyard pin in the
4-1/2″ position on the cutting height index. Release the deck from the
transport position and allow the deck to move to the 4-1/2″ cutting height
position.
2. Check the measurement from the floor to the cutter blade tip. If the
measurement is not at 4-1/2″, an adjustment can be made using the deck height
control rod.
3. Loosen the jam nuts on both ends of the deck height control rod. See
Figure 6-8.

Section 6 R
6.7 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 seven (7) different positions for optimum
performance.
A. 3-1/2″ or 3-3/4″ Position – (See Figure 6-9). For very tall, wiry or tough-
to-cut grass.
B. 4″ (factory setting), 4-1/4″ or 4-1/2″ Position – (See Figure 6-9). For
general purpose cutting. This gives the best mix of cutting performance in all
types of grass.
To adjust the Custom-Cut Baffle height:
1. Place the cutter deck in the transport position.
2. Remove the hardware securing the Custom-Cut Baffle to the cutter deck.
– NOTE Hardware location used in the illustrations are for reference only.
Location of hardware may vary depending on cutter deck size.
3. Move the Custom-Cut Baffle to desired position. See Figure 6-9.
4. Reinstall the mounting hardware. Torque hardware to 39 ft-lbs.
C. 4-3/4″ or 5-1/4″ Position – (See Figure 6-9). Placing the baffle in either the 4-3/4″ or 5-1/4″ setting will enhance fall cutting (leaf pickup) and reduce cutter deck “blowout”.

6.8 ADJUSTING THE STEERING DAMPNERS
The steering dampner adjustment can be made to increase or decrease the
dampening affect for smooth, precise steering control. There are three
locations on the steering control levers that allow the operator to adjust the
dampening affect of the steering control based on cutting conditions.
1. Top Mounting Location (Figure 6-10). Used for the highest dampening affect
on the steering controls.
2. Middle Mounting Location (Figure 6-10). Used for average dampening affect
on the steering controls.
3. Bottom Mounting Location (Figure 6-10). Used for the lowest dampening
affect on the steering controls.
6.9 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.
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 6-10.

Figure 6-13. Clutch Air Gap Adjustment 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.

7.12 HYDRAULIC SYSTEM
B. CHANGING HYDRAULIC OIL
A. CHECKING HYDRAULIC OIL LEVEL
The hydraulic oil level should be checked after the first 10 hours of
operation. Thereafter, check the oil after every 200 hours of machine
operation or monthly, whichever occurs first.
– IMPORTANT –
If the oil level is consistently low, check for leaks and correct immediately.
1. Tilt the seat forward to access the hydraulic oil reservoir. Wipe dirt and
contaminants from around the reservoir cap. Remove the cap from the hydraulic
oil reservoir.
2. Visually check the level of hydraulic oil. Hydraulic oil must be at least
2″ inches from top of the filler neck. If the level cannot be determined
visually, use a clean tape measure to check the level. If the fluid is low,
add 20W50 motor oil (Scag p/n 486255 – 1 Quart or p/n 486254 – 1 Gallon). DO
NOT overfill; (overfilling the oil reservoir may cause oil seepage around the
cap area).
3. Clean the fill cap and install it onto the reservoir.
The hydraulic oil should be changed after every 500 hours or annually,
whichever occurs first. The oil should also be changed if the color of the
fluid has become black or milky. A black color and/or a rancid odor usually
indicates possible overheating of the oil, and a milky color usually indicates
water in the hydraulic oil.
– IMPORTANT –
The hydraulic oil should be changed if you notice the presence of water or a
rancid odor to the hydraulic oil.
1. Park the mower on a level surface and stop the engine.
2. Place a suitable container under the hydraulic oil filter. Tilt the seat
forward. Remove the fill cap from the reservoir and the drain plug from the
bottom of the drain tee fitting on the front side of the filter base. See
Figure 7-3. Allow the fluid to drain into the container and properly discard
it.

7.16 BATTERY
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.
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.
Section 7
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.
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
1. The booster battery must be a 12 volt type. If a vehicle is used for jump
starting, it must have a negative ground system.
2. When connecting the jumper cables, connect the positive cable to the
positive battery post, then connect the negative cable to the negative battery
post.
7.17 DRIVE BELTS
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.
44
Section 7 R
– NOTE –
If you experience frequent belt wear or breakage, see your Authorized Scag
Power Equipment service center for belt adjustment.
– 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.
WARNING
If the pump drive belt fails, steering control will be lost which could result
in serious injury or death. Replace the pump drive belt as needed or every 400
hours / 2 years, whichever occurs first.
7.18 CUTTER BLADES
A. BLADE INSPECTION
1. Remove the ignition key before servicing the blades. 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.
WARNING
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
7-6.
1. Sharpen the cutting edge at the same bevel as the original. See Figure
7-6. Sharpen only the top of the cutting edge to maintain sharpness.
Do Not Cut In
Angle Blade Back
X
Always wear proper hand and eye protection when working with cutter blades.
3. Check the cutter blades for wear. If any part of the cutter blade is worn
to 1/2 its original thickness, replace the cutter blade.
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.
X Must NOT Exceed
30
1/3 Blade Width
Figure 7-6. Blade Sharpening
2. Check the balance of the blade. If the blades are out of balance,
vibration and premature wear can occur. The cutter blades should be balanced
to 1-1/2 oz-in. See your authorized Scag dealer for blade balancing or special
tools, if you choose to balance your own blades.
4. Check the cutter blades for gouges. If there are gouges on the top or
bottom surfaces of the cutter blade, replace the cutter blade.
5. If a blade cutting edge is dull or nicked, it should be sharpened. Remove
the blades for sharpening. See Blade Replacement, Section 7.9C

C. BLADE REPLACEMENT
WARNING
HEX NUT-TORQUE TO 75 LB-FT
Always wear proper hand and eye protection when working with cutter blades.
1. Remove the ignition key before replacing the blades.
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 nut from the blade attaching bolt. Remove the cutter blade, bolt and
spacer from the spindle shaft. See Figure 7-7.
– NOTE The front of the machine will have to be raised slightly to remove the
blade bolt from the cutter spindle.
CAUTION
Inspect the cutter blade spacer(s) and washer for wear and/or cupping. Replace
the worn parts. Worn spacer(s) and/or washer will not allow proper tightening
of the cutter blade and can lead to cutter blade failure, personal injury or
property damage.
4. To install the new cutter blade, put the flat washer onto the blade bolt
and slide the bolt into the hole in the cutter blade.
