6. Operator hearing protection is recommended, particularly for continuous operation of the mower. W ear suitable hearing protection. Prolonged exposure to loud noise can cause hearing impairment or loss.
7. Keep the machine and attachments in good operating condition. Keep all shields and safety devices in place. If a shield, safety device or decal is defective or damaged, repair or replace it before operating the machine.
WARNING:
This machine is equipped with an interlock system intended to protect the operator and others from injury. This is accomplished by preventing the engine from starting unless the operator is seated in the seat, the deck drive is disengaged, and the speed control is placed in the neutral position. The system also shuts off the engine if the operator leaves the seat with the mower running and the speed control is not in the neutral postion. It will also shut off the engine if the hopper is raised with the cutter deck drive engaged. Never operate equipment with the interlock system disconnected or malfunctioning.
8. Be sure interlock switches are functioning correctly.
13. DO NOT operate without a chute deflector installed;
keep the deflector in lowest possible position.
14. Check the blade mounting bolts at frequent intervals for proper tightness.
15. Make sure all hydraulic fluid connections are tight and all hydraulic hoses and lines are in good condition before starting the machine.

4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system that prevents the engine from starting unless the deck drive is disengaged and the speed control is in neutral. The interlock system shuts off the engine if the operator leaves the seat with the speed control not in the neutral position and/or the cutter blades are engaged. It will also shut the engine off if the cutter deck drive is engaged and the hopper is raised.
WARNING:
Never operate the mower with the interlock system disconnected or malfunctioning. Do not disengage or bypass any switch; injury to yourself and others or property damage could result.
4.3 INITIAL RUN-IN PROCEDURES (First Day of Use or Approximately 10 Hours)
4.4 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 under the fuel tank, is completely open. (See section 7-4.)
2. Sit in the operator’ s seat and place the speed control in the neutral position.
3. Engage the parking brake.
4. If the engine is cold, adjust the engine choke as needed.
1. Check all belts for proper tension at 2, 4 and 8 hours.
2. Change the engine oil and oil filter after the first 5 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 4.2.)
6. Check tire pressure. Inflate tires if necessary.
5. Adjust engine throttle control to about half engine speed.
6. Turn the ignition key to the ST ART position and release the key as soon as the engine starts. Do not hold the key in the ST ART 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.
7. Allow engine to warm before operating the mower.
4.5 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. Practice until you are comfortable with the handling of the machine before attempting to mow. Learn the operation on flat ground before operating on slopes.
10
Page 17
Section 4
-IMPORT ANT-
Start practice with a slow engine speed and slow forward travel.
Do not push the steering control levers forward when traveling forward. They are only used to steer the mower and to travel in reverse by pulling back on the levers.
Learn to operate the mower with the left hand on the steering levers and the right hand on speed control as shown in Figure 4-5. Using both hands on the steering levers often causes overcontrol.
Learn to feather the steering controls to obtain a smooth operating action. Jerky movements tend to place extreme force on the drive pumps and axles, as well as damage the lawns.
Practice operating the mower until you can make it go exactly where you are aiming.
In case of an emergency, such as loss of control, stop the mower’s movement by quickly pulling the speed control lever to the neutral position.
Forward Travel
-NOTE-
Use one hand on both steering levers as shown in Figure 4-5 to minimize overcontrol.
T o travel forward with the mower , move the speed control lever forward. Do not push the steering control levers forward as they are used only for steering the mower left or right. When the speed control is moved forward, the mower will travel forward at the speed the control lever is set at. To increase the speed, push the control lever forward and to decrease the speed, pull the control lever back. It is not necessary to hold the speed control in position, since a friction system holds the lever in position.
T o stop the forward travel, pull the speed control lever back to the neutral position.
T o steer the mower left while traveling forward, pull the left steering lever back. The further the lever is pulled back, the further the mower will turn left.
Figure 4-5 Hands On Controls
T o steer the mower right while traveling forward, pull the right steering control lever back. The further the lever is pulled back, the further the mower will turn right.
-NOTE-
Smooth operation of the steering levers will produce a 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. Tilt the deck and travel backwards over the curb at a 45 degree angle. (see section 4.15 for cutter deck tilting instructions)

Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.
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.
T o travel in reverse, pull both handles all the way back. Keep the travel speed low while traveling in reverse.
4.6 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 switch lever (Figure 4-6) then pushing the switch lever forward to the engage position.
UP FOR MOWER - ON
PULL OUT
DOWN FOR MOWER - OFF
-NOTE-
The mower will not travel straight in reverse. Slight adjustments must be made using the steering controls.
T o 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 further the mower will turn left.
T o 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 further the mower will turn right.
T o stop the reverse travel, place the speed control lever in the neutral position and allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake.
Figure 4-6 Cutter Engage Switch
-NOTE-
If a squealing noise is heard when engaging or disengaging the deck drive, it is caused by the electric clutch plates meshing as the mower comes up to speed.
3. To disengage the deck drive, pull the switch lever down 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.

4.7 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. A v oid 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. W et grass reduces traction and steering control.
Figure 4-8 Improper Operation on a Slope
2. To inhibit tipping or loss of control, do not start or stop suddenly , avoid unnecessary turns and travel at reduced speed.
3. Keep tires properly inflated.
4. Always travel up or down the slope, whenever possible; NEVER across the slope. (See Figures 4-7 and 4-8.)
4.8 PARKING THE MOWER
1. Place the speed control in the neutral position.
2. Slow the engine to idle speed.
3. Engage the parking brake.
4. Turn the ignition key to the OFF position and remove the key .
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not use high pressure spray or direct the spray onto electrical components.
-IMPORT ANT-
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.
Figure 4-7 Proper Operation on a Slope
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 tension, alignment and any signs of rubbing. Correct and adjust if necessary.
13
Page 20
Section 4
4. Fill the fuel tank with fresh, clean fuel at the end of every day of operation.
5. Check the tire pressure. Inflate tires if necessary.
4.10 HOPPER/SIDE DISCHARGE
OPERATION
A control lever located on the left side of the tractor selects either hopper discharge or side discharge to the outside. When the lever is placed in the hopper position (Figure 4-9), the side discharge is covered and the hopper discharge is opened. When the lever is placed in the side discharge position (Figure 4-10), the hopper discharge is covered and the side discharge is opened.
-NOTE-
If the control lever sticks, push the r elease lever to free it.
Grass Catching Operation
CAUTION:
Never leave grass clippings in the hopper after mowing. Wet or damp clippings will generate heat as they decompose which may cause spontaneous combustion to occur.
1. Place the hopper/side discharge control lever in the hopper discharge position (Figure 4-9).
2. With the hopper lowered, engage the deck drive. When the deck drive is engaged, the grass delivery spout, which is designed to distribute the grass clippings through the inside of the hopper, will begin to oscillate. If the spout does not oscillate, do not use the grass catcher. Use the side dischar ge and then have the oscillating spout system repaired.
Release Lever in This Position for Hopper Discharge
Figure 4-9 Hopper Operation Position
Release Lever in This Position for Side Disharge
Figure 4-10 Side Discharge Operation Position
-NOTE-
The mower has an interlock switch that will prevent the mower from starting if the hopper is in the raised position. This interlock switch will also shut the engine off if the hopper is raised while the engine is running and the deck drive is engaged.
3. Proceed to mow the lawn until the hopper is full. If your mower is not equipped with the optional hopper full alarm to tell you when the hopper is full, check the hopper frequently when first using the grass catcher. After operating with the grass catcher for awhile, experience will tell you when the hopper is full.
4. When dumping the hopper into a disposal area:
A.Disengage the deck drive.
WARNING:
Never operate the grass catcher with the hopper back door open. Objects can be thrown out the spout of the hopper with a force that can cause injury to bystanders or property damage.
14
Page 21
Section 4
B. Raise the tailgate until the u-bolt on top of the
hopper engages with the latch on the tailgate (Figure 4-11).
U-Bolt and Latch
Figure 4-11 Tailgate Operation
E. Release the latch holding the tailgate and then
lower the tailgate. Be careful when lowering the tailgate. It is spring loaded and will close with some force.
Side Discharge Operation
CAUTION:
The side discharge chute can throw objects with great force. Do not stand in front of discharge chute when the cutter deck is engaged.
When mowing, never discharge toward bystanders or buildings. Do not allow anyone near the machine while
in operation.
1. Place the hopper/side discharge control lever in the
side discharge position (Figure 4-10).
C. Stand off to side of the hopper . Raise the hopper
by placing a hand in the hand hole at either bottom front side of the hopper (Figure 4-12) and then carefully lift the hopper until it is in its upright position and the hopper is emptied.

D. Carefully lower the hopper.
2. Engage the deck drive.
3. Proceed to mow the lawn.
4.11 REMOVING CLOGGED MATERIAL
ROTATING BLOWER BLADES
NEVER PUT YOUR HANDS INTO THE BLOWER 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 either blower 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.
15
Page 22
Section 4
2. If the blower intake becomes clogged, there could be a distinct change in the sound of the blower and/or the mower deck will begin to leave a trail of glass clippings. The clogging will generally develop in the back of the mower deck in the opening of the blower chute. When clogging occurs at this point, it's usually caused by something restricting the flow throughout the entire system and the system should be checked if a pattern develops.
3. Check the following:
A. Check that the blades are properly installed for
correct rotation. See Section 7.
B. Check that the cutting height is not too low.
When cutting thick, tall grass, lower cutting height settings tend to restrict the airflow moving into and under the deck.
C. Check that the deck housing and baffling is free
of grass and dirt buildup. Some material buildup can be tolerated, but when a buildup occurs that restricts the flow of air and grass clippings, the mower deck must be cleaned.
D. Check that the blades have enough flat section at
the blade tip. Sharpening of the blades will remove this flat section and if too much is removed, the air lift capability of the blade is greatly reduced. Replace the blades if more than 1/3 of blade is removed at the blade tip. See section 7.10.
4.12 MOVING MOWER WITH ENGINE STOPPED
T o “free-wheel” or move the mower around without the engine running, place the dump valve handle in the FREE-WHEEL position (Figure 4-2). Disengage the parking brake and move the mower by hand. The lever must be returned to the DRIVE position to drive the mower.
4.13 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. A dull blade will tear grass, resulting in poor lawn appearance and requiring extra power.
2. 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 system 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.
E. Check the discharge chutes for accumulation of
dirt and material that would restrict flow . Clean the discharge chutes as described above.
F. Check the elbow inside the hopper for a buildup
of material in the radius.
G. Check that the screen in the hopper is not
plugged with materials. If plugged, remove and clean screen as described in section 7.13.
H. Remember, anything that restricts airflow or
material flow along the entire path from the mower deck to the hopper can cause clogging.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at or near 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.

4.14 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1-inch to 4-1/2 inches at 1/2-inch intervals. T o adjust the cutting height:
WARNING:
Do not adjust the cutting height with the mower blades rotating. Shut off the engine and remove the ignition key. Bodily injury could occur from the rotating blades.
1. Shut off the engine and remove the ignition key.
2. Remove the two hairpins from the adjusting pins on one side of the cutter deck (Figure 4-13).
3. Lift or lower the deck to the desired cutting height and install the hairpins. A deck height decal is located on the deck as an aid in adjusting the deck to the desired height.
4.15 TILTING THE CUTTER DECK
WARNING:
Do not tilt the mower deck with the mower blades rotating. Shut off the engine and remove the ignition key. Bodily injury could occur from the rotating blades.
The mower deck can be tilted up for road travel, blade replacement, etc. T o tilt the deck up:
1. Shut off the engine and remove the ignition key.

6.2 TRA VEL ADJUSTMENTS
Neutral or tracking adjustments will need to be made if:
A. The speed control lever is in neutral and the
machine creeps forward or backward. (Neutral Adjustment)
B. The mower pulls to one side or the other when
traveling in a forward direction. (Tracking Adjustment).
If the mower creeps forward or backward as indicated in "A" above, the neutral linkages must be adjusted. Start with adjusting the speed control lever and proceed as directed. T o correct the tracking of the mower (mower pulls to one side when traveling in a forward direction), adjust the tracking of the mower as described on page 27.
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.
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.
Speed Control Lever Adjustment
-IMPORTANT-
Before proceeding with this adjustment, be sure that the tire pressure in the three tires is correct, that the caster wheels turn freely, and that the two transmission drive belts are adjusted for the correct tension.
1. Place the speed control lever in the neutral position (Figure 6-4).
24

3. If the adjustments are okay and you need to adjust
the neutral linkages, proceed with the Neutral Adjustment procedures. If the speed control requires adjustment, adjust as follows:
A. Loosen both jam nuts (A & B, Figure 6-6) on the
adjusting rod (C).
-NOTE-
All turnbuckles have a left hand threaded nut and a right hand threaded nut. The left hand nut is located next to the ball joint that has a groove etched into its outer surface.
B. Using a wrench on the hex portion of the
adjusting rod, turn the adjusting rod (C) in the required direction to move the bellcrank against the bushing. When the correct adjustment is obtained, tighten the two jam nuts (A & B).
2. Check that the speed control bellcrank (Figure 6-5) is touching the bushing on the frame and that the block on the speed control lever has engaged the neutral switch (Figure 6-4). The switch button should not be fully compressed. If the switch is engaged, but the bellcrank is not touching the bushing, full speed will not be obtainable.
Resting On Bushing
C. Proceed with the Neutral Adjustment.
Neutral Adjustment
1. Locate the left hand speed control lever. Using a ruler, check the distance between the ball joint and the center of the pivot point of the lever (Figure 6-6). The dimension must be 4-1/2 inches or be in the center of the slot. If correct, proceed to step 2. If incorrect, loosen the lock nut securing the ball joint to the lever and relocate the ball joint to the correct position.
2. Loosen the two jam nuts (D & E, Figure 6-6) on the right side neutral linkage and the two jam nuts (F & G) on left side neutral linkage.
3. With a person seated in the operator’s seat, disengage the parking brake and start the mower’s engine.
Figure 6-5 Bellcrank Touching Bushing
4. SLOWLY rotate the turnbuckle (H, Figure 6-6) on the right side until the mower starts to creep forward. When the mower starts to creep forward, stop the movement and turn the turnbuckle back 1/2 turn or three flats (Figure 6-6).

7. Tighten jam nuts (F & G) on the left side and remaining jam nut (D) on the right side.
8. When the speed control lever is actuated, the mower should travel in a straight line. If it travels straight, perform the Tracking Adjustment procedures. If the mower pulls to one side, it is an indication that one of the wheels is coming out of neutral before the other . This condition must be corrected as follows:
A. If the mower pulls to the right, it is an indication
that the left wheel is coming out of neutral before the right wheel. If the mower pulls to the left, it is an indication that the right wheel is coming out of neutral before the left wheel.

1) If the mower pulls to the left, loosen both jam nuts (F & G) and lengthen turnbuckle (J). T ighten the jam nuts and drive the mower forward. Repeat this procedure until both wheels start to turn at the same time.
2) If the mower pulls to the right, loosen both jam nuts (F & G) and shorten turnbuckle (J). Tighten the jam nuts and drive the mower forward. Repeat this procedure until both wheels start to turn at the same time.
-NOTE-
This adjustment affects the tracking of the mower. Turning the turnbuckle (J) one or two flats has an adverse effect throughout the tracking range.
If the mower pulls one way at slow speed and then pulls the other way at fast speed, a tracking adjustment needs to be done.

Tracking Adjustment
-IMPORTANT-
Before proceeding with this adjustment, be sure that the tire pressure in the three tires is correct, that the caster wheels turn freely, and that the two transmission drive belts are adjusted for the correct tension.
The mower tracking should be adjusted if during low speed the mower pulls in one direction and then pulls in the opposite direction as you go faster.
1. If at full speed the mower pulls right, it is an indication that the left wheel is turning too fast. T o adjust this condition, loosen the lock nut securing the swivel joint (N, Figure 6-6) to the left hand control lever . Move the linkage outward in the slot. This will lengthen the control arm and cause it to stroke the pump less, slowing down the left wheel.
Figure 6-7 Gap Measurement
2. If at full speed the mower pulls to the left, it is an indication that the left wheel is turning too slow. To adjust this condition, loosen the locknut securing the swivel joint (N) to the left hand control lever . Move the linkage inward in the slot. This will shorten the control arm and cause it to stroke the pump more, speeding up the left wheel.
Steering Handle Adjustment
-NOTE-
Changing the Neutral Adjustment will move the handle locations.
Check for a 3/4 inch gap between the control levers and the frame (Figure 6-7). If this gap is not correct between either handle, adjust the gap as follows:
1. Shut off the mower’s engine and engage the parking brake.
2. Tilt the mower deck and lock it in place with the two deck prop rods. Refer to Section 4 for the correct procedure.
3. Remove the two deck springs and swing the deck spring bracket up. If this is not done, the bracket will contact the control levers when the seat is raised.
Figure 6-8 Raised Seat Bracket
4. Raise the seat far enough to gain access to the control linkages, but not far enough to contact the control levers with the seat bracket. Support seat bracket in the raised position.
5. Loosen the two jam nuts (K & L, Figure 6-6) on the left control linkage. Turn the turnbuckle (M) until a gap of 3/4 inches is obtained between the handle and the frame. Tighten the two jam nuts (K & L).
6. Loosen the two jam nuts (N & P) on the right control linkage. Turn the turnbuckle (Q) until the right handle is in line with the left handle (Figure 6-6). Tighten the two jam nuts (N & P).

7.7 BATTERY
A. Checking Electrolyte Level and Cleaning Battery
After every 40 hours of operation or weekly , whichever occurs first, check the electrolyte level in the battery and clean the battery and connections. Dirt and fluid on the top of the battery can cause the battery to discharge. Corrosion of the battery terminals or loose connections will cause poor battery performance.
WARNING:
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.
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.
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.
1. Loosen the two plastic wing nuts under fender and then
remove the battery cover .
2. Remove the battery cell caps. Visually inspect
electrolyte level in the cells. If electrolyte is below the bottom of vent well, fill with clean distilled water to the bottom of vent wells (1/4 to 1/2 inch above the plates). Install the battery cell caps.
35
Page 42
-IMPORTANT-
Do not overfill the battery. Electrolyte will overflow through the vent tube onto parts of the machine, resulting in severe corrosion.
3. Clean the cable ends and battery posts with steel wool. Use a solution of baking soda and water to clean the battery . Do not allow the solution to enter the battery cells.
4. Tighten the cable connections securely and apply a light coat of silicone dielectric grease to the terminal connections to prevent corrosion.
Section 7
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.
5. Install the battery cover.
B. 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.
C. 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.
7.8 DRIVE BELTS
After the first 2, 4, 8 and 10 hours of operation, check for proper tension on all drive belts and check for any damage. Thereafter, check the belt tension after every 100 hours of operation or bi-weekly , whichever occurs first.

machine should be trained in its proper use, warned of its dangers, and should read the entire
manual before attempting to set up, operate, adjust or service the machine.
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. Accordingly, any such implied warranties including merchantability, fitness for a particular purpose, or otherwise, are disclaimed in their entirety after the expiration of the appropriate one year or ninety day warranty period. 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.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for gasoline, expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner, mechanics travel time, telephone or telegram charges, rental of a like product during the time warranty repairs are being performed, travel, loss or damage to personal property, loss of revenue, loss of use of the mower, loss of time or inconvenience. 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.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
