2 SAFETY

2.1 OPERATING SAFETY ______________________________________________________

WARNING

EQUIPMENT OPERATED IMPROPERLY OR BY UNTRAINED PERSONNEL CAN BE DANGEROUS.

Familiarize yourself with the location and proper use of all controls. Inexperienced operators should receive

instruction from someone familiar with the equipment before being allowed to operate the machine.

1. Safety is dependent upon the awareness, concern, and prudence of those who operate or service the equipment. Never allow minors to operate any equipment.

2. It is your responsibility to read this manual and all publications associated with this equipment (Parts and Maintenance Manual, Engine Manual, and attachments/accessories instruction sheets). If the operator cannot read English it is the owner’s responsibility to explain the material contained in this manual to them.

3. Learn the proper use of the machine, the location and purpose of all the controls and gauges, before you operate the equipment. Working with unfamiliar equipment can lead to accidents.

4. Never allow anyone to operate or service the machine or its attachments without proper training and instructions; or while under the influence of alcohol or drugs.

5. Wear all the necessary protective clothing and personal safety devices to protect your head, eyes, ears, hands, and feet. Operate the machine only in daylight or in good artificial light.

6. Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Jacobsen.

7. Stay alert for holes in the terrain and other hidden hazards.

8. Inspect the area where the equipment will be used. Pick up all the debris you can find before operating. Beware of overhead obstructions (low tree limbs, electrical wires, etc.) and also underground obstacles (sprinklers, pipes, tree roots, etc.). Enter a new area cautiously. Stay alert for hidden hazards.

9. Never direct discharge of material toward bystanders, nor allow anyone near the machine while in operation. The owner/operator can prevent and is responsible for injuries inflicted to themselves, to bystanders, and damage to property.

10. Do not carry passengers. Keep bystanders and pets a safe distance away.

11. Never operate equipment that is not in perfect working order or is without decals, guards, shields, discharge deflectors, or other protective devices securely fastened in place.

12. Never disconnect or bypass any switch.

13. Do not change the engine governor setting or overspeed the engine.

14. Carbon monoxide in the exhaust fumes can be fatal when inhaled. Never operate the engine without proper ventilation or in an enclosed area.

15. Fuel is highly flammable; handle with care.

16. Keep the engine clean. Allow the engine to cool before storing and always remove the ignition key.

17. Disengage all drives and engage parking brake before starting the engine (motor). Start the engine only when sitting in operator’s seat, never while standing beside the unit.

18. Equipment must comply with the latest federal, state, and local requirements when driven or transported on public roads. Watch out for traffic when crossing or operating on or near roads.

19. Local regulations may restrict the age of the operator.

20. Operate the machine up and down the face of slopes (vertically), not across the face (horizontally).

21. To prevent tipping or loss of control, do not start or stop suddenly on slopes. Reduce speed when making sharp turns. Use caution when changing directions.

22. Always use the seat belt when operating mowers equipped with a Roll Over Protective Structure (ROPS).

Never use a seat belt when operating mowers without a ROPS.

Accessory operator protective structures will continue to be offered for all equipment currently covered. This allows for the outfitting of any machines without previous ROPS installations or replacement of damaged structures.

23. Keep legs, arms and body inside the seating compartment while the vehicle is in motion.

This machine is to be operated and maintained as specified in this manual and is intended for the professional maintenance of specialized turf grasses. It is not intended for use on rough terrain or long grasses.

SAFETY 2

2.2 IMPORTANT SAFETY NOTES ________________________________________________

This safety alert symbol is used to alert you to potential hazards.

DANGER - Indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury.

WARNING - Indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious

injury.

CAUTION - Indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury

and property damage. It may also be used to alert against unsafe practices.

NOTICE - Indicates a potentially hazardous situation which, if not avoided, MAY result in property damage. It may

also be used to alert against unsafe practices.

For pictorial clarity, some illustrations in this manual may show shields, guards, or plates open or removed. Under no circumstances should this equipment be operated without these devices securely fastened in place.

WARNING

The Interlock System on this mower prevents the mower from starting unless the brake lever is engaged, mower switch is off, and traction pedal is in neutral. The system will stop the engine if the operator leaves the seat without engaging the parking brake or setting the mower switch off.

NEVER operate mower unless the Interlock System is working.

WARNING

1. Before leaving the operator’s position for any reason:

a. Return traction pedal to neutral. b. Disengage all drives. c. Lower all implements to the ground. d. Engage parking brake. e. Stop engine and remove the ignition key.

2. Keep hands, feet, and clothing away from moving parts. Wait for all movement to stop before you clean, adjust, or service the machine.

3. Keep the area of operation clear of all bystanders and pets.

4. Never carry passengers, unless a seat is provided for them.

5. Never operate mowing equipment without the discharge deflector securely fastened in place.

By following all instructions in this manual, you will prolong the life of your machine and maintain its maximum efficiency. Adjustments and maintenance should always be performed by a qualified technician.

If additional information or service is needed, contact your Authorized Jacobsen Dealer, who is kept informed of the latest methods to service this equipment, and can provide prompt and efficient service. Use of other than original or

authorized Jacobsen parts and accessories will void the warranty.

6.3 OPERATING PROCEDURES _________________________________________________

WARNING

A Roll Over Protection Structure (ROPS) is included with this mower. Seat belts must be worn whenever operating a mower with a ROPS. Always keep seat belt snugly adjusted. DO NOT use seat belts on a mower without a ROPS.

If the mower is overturning, hold onto the steering wheel. Do not attempt to jump out or leave the seat.

CAUTION

To prevent injury, always wear safety glasses, leather work shoes or boots, a hard hat, and ear protection.

1. Under no circumstances should the engine be started without the operator seated on the mower.

2. Do not operate mower or attachments with loose, damaged, or missing components. Whenever possible mow when grass is dry.

3. First mow in a test area to become thoroughly familiar with the operation of the mower and control levers.

Never operate the reels unless they are mowing grass. Heat will develop between the bedknife and reel and damage the cutting edge.

4. Study the area to determine the best and safest operating procedure. Consider the height of the grass, type of terrain, and condition of the surface. Each condition will require certain adjustments or precautions.

5. Never direct discharge of material toward bystanders, nor allow anyone near the machine while in operation. The owner/operator is responsible for injuries inflicted to bystanders and/or damage to their property.

CAUTION

Before mowing, pick up all debris such as rocks, toys, and wire which can be thrown by the machine. Enter a new area cautiously. Always operate at speeds that allow you to have complete control of the mower.

8. Disengage the drive motors and raise the reels when crossing paths or roadways. Look out for traffic.

9. Stop and inspect the equipment for damage immediately after striking an obstruction or if the machine begins to vibrate abnormally. Have the equipment repaired before resuming operation.

WARNING

Before you clean, adjust, or repair this equipment, always disengage all drives, lower implements to the ground, engage parking brake, stop engine, and remove key from ignition switch to prevent injuries.

10. Slow down and use extra care on hillsides. Read Section 6.7. Use caution when operating near drop offs.

11. Look behind and down before backing up to be sure the path is clear. Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

12. Never use your hands to clean cutting units. Use a brush to remove grass clippings from blades. Blades are extremely sharp and can cause serious injuries.

6. Use discretion when mowing near gravel areas (roadway, parking areas, cart paths, etc.). Stones discharged from the implement may cause serious injuries to bystanders and/or damage the equipment.

7. Always turn reel switch off to stop blades when not mowing.

6 OPERATION

6.4 STARTING _______________________________________________________________

IMPORTANT: Do not use starting assist fluids. Use of

such fluids in the air intake system may be potentially explosive or cause a “Runaway” engine condition and could result in serious engine damage.

1. Make sure fuel shut off valve is completely open and the tow valve (See Section 6.9) is closed.

2. Sit in operator’s seat, make sure reel switch (T) is OFF, parking brake (C) is engaged, and traction pedal (E and F) is in neutral.

To prevent tipping or loss of control, travel at reduced speed when making turns.

6.7 HILLSIDE OPERATION _____________________________________________________

1. Always mow with the engine at full throttle but reduce

WARNING

To minimize the possibility of overturning, the safest method for operating on hills and terraces is to travel up and down the face of the slope (vertically), not across the face (horizontally). Avoid unnecessary turns, travel at reduced speeds, and stay alert for hidden hazards and drop offs.

forward speed to maintain the proper cutting frequency.

2. If the mower tends to slide or the tires begin to

“mark” the turf, angle mower into a less steep grade until traction is regained or tire marking stops.

3. If mower continues to slide or mark the turf, the

grade is too steep for safe operation. Do not make another attempt to climb, and back down slowly.

CAUTION

Do not operate this mower on slopes greater than 20°.

The mower has been designed for good traction and stability under normal mowing conditions; however, use caution when operating on slopes, especially over rough terrain, or when the grass is wet. Wet grass reduces traction and steering control.

4. When descending a steep slope, always lower

implements to the ground to reduce the risk of mower overturning.

Correct tire pressure is essential for maximum traction. Front and Rear - 10-12 psi (0.69 - 0.83 BAR).

6.8 MOWING_________________________________________________________________

WARNING

To prevent serious injuries, keep hands, feet, and clothing away from cutting unit when the blades are moving.

NEVER use your hands to clean cutting units. Use a brush to remove grass clippings from blades. Blades can be sharp and could cause injuries.

To clear obstructions from cutting unit, disengage reel switch, engage parking brake, stop engine, and remove key from ignition switch; then remove obstruction.

To mow:

1. Start the engine and lower the mowers to the ground.

2. Turn reel switch to ON and disengage parking brake.

To prevent damage to the reel and bedknife, never operate reels when they are not cutting grass.

3. Move throttle lever to FAST then slowly depress traction pedal to the desired mowing speed.

a. For complete even cutting, overlap swaths by a

few inches.

b. Stop and raise the mowers to the transport

position when crossing paths or roadways. Look out for traffic.

4. To remove or install the grass catchers, lower the cutting units to the ground, engage the parking brake, and shut off the engine. Tilt the grass catcher body so the front edge clears the mower frame, and slide the catcher onto or off of the catcher frame.

NOTICE

6.9 TOWING / TRAILERING _____________________________________________________

If the mower experiences problems and must be shut down and removed from the area, it should be loaded onto a trailer for transport. If a trailer is not available, the unit can be towed slowly short distances.

Use care when loading and unloading mower. Fasten mower to trailer to prevent mower from rolling or shifting during transport.

Long Distance Trailering / Transport. If the mower is to be trailered on the highway, before strapping to trailer, inflate tires to:

Front - 18 psi (1.24 BAR) Rear - 24 psi (1.65 BAR) After unloading mower, reduce tire pressure to normal operating pressure. See Section 6.7

Before towing, open tow valve. The tow valve permits moving the mower without starting the engine and prevents possible damage to hydraulic components.

The tow valve (A) is located on the bottom of the drive pump under the mower. To open valve, loosen jam nut on valve stem and turn valve counterclockwise.

Before towing make sure cutting units are raised. If they cannot be raised, remove them from the mower.

Close valve completely and lock in place with jam nut after towing.

NOTICE

Do not exceed 2 MPH (3.2 KPH) while towing. Long distance towing is not recommended.

9.11 BEDKNIFE-TO-REEL _______________________________________________________

(Pre-adjustment Check)

1. Check the reel bearings for end play or radial play.

There should be no end play or radial play. See Section

9.14.

CAUTION

To prevent personal injury and damage to the cutting edges, wear gloves and handle the reel and bedknife with extreme care.

2. Inspect the reel blades and bedknife to insure good

sharp edges without bends or nicks.

a. The leading edge of the reel blades (A) must be

sharp, free of burrs, and show no signs of rounding off.

b. The bedknife and bedknife backing must be

securely tightened. The bedknife must be straight and sharp.

c. A flat surface of at least 1/16 in. (1.5 mm) minimum

must be maintained on the front face of the bedknife. Use a standard flat file to dress the bedknife.

3. If wear or damage is beyond the point where the reel

or bedknife can be corrected by the lapping process, they must be reground.

4. Proper reel-to-bedknife adjustment is critical. A gap of

0.001 to 0.003 in. (0.025 to 0.076 mm) must be maintained across the entire length of the reel and bedknife.

5. The reel must be parallel to the bedknife. An

improperly adjusted reel will lose its sharp edges prematurely and may result in serious damage to the reel and bedknife.

Figure 9K

6. Grass conditions will also affect the adjustment.

a. Dry, sparse conditions will require a wider gap to

prevent heat buildup and damage to the reel and bedknife.

b. High quality grass with a good moisture content

requires a closer gap (near zero).

Figure 9J

9 ADJUSTMENTS

9.12 BEDKNIFE ADJUSTMENT __________________________________________________

1. Read Section 9.11 before making the adjustment.

7. Start adjustment at the leading end of the reel, followed by the trailing end. The leading end of the

reel blades is that end which passes over the bedknife first during normal reel rotation.

8. Use adjusters (B and C), to adjust gap. Rotate adjusters (Clockwise) to close gap. Each click of the adjuster moves the bedknife 0.001” (0.025 mm) closer to the reel.

a. Slide a feeler gauge or shim stock 0.001” - 0.003”

(0.025 - 0.075 mm) between the reel blade and the bedknife. Do not turn the reel.

b. Adjust the trailing end of the reel to the same

gap in a similar manner then recheck the adjustment at the leading end.

c. When the reel is properly adjusted to the

bedknife, the reel will spin freely and you should be able to cut a piece of newspaper, along the full length of the reel, when the paper is held at 90° to the bedknife.

Avoid excessive tightening or serious damage may result to bedknife and reel blades. Reels must turn freely.

QUALITY OF CUT 11

TN0159

11 QUALITY OF CUT

11.1 QUALITY OF CUT PROBLEM SOLVING________________________________________

It is recommended that a “test cut” be performed to evaluate the mower’s performance before beginning repairs.

An area should be available where “test cuts” can be made. This area should provide known and consistent turf conditions to allow accurate evaluation of the mower’s performance.

Another “test cut” should be performed after the completion of the repairs and/or adjustments to verify the mower’s performance.

Before performing a “test cut” to diagnose cut appearance and mower performance, the following items should be verified to ensure an accurate “test cut.”

1. Mowing (Ground) Speed.

2. Reel Bearing Condition and Pre-Load (End Play) Adjustment.

3. Reel and Bedknife Sharpness.

4. Bedknife Alignment to Reel.

5. Reel-to-Bedknife Contact.

6. Height-of-Cut (HOC).

7. Roller and Roller Bearing Condition.

11.2 WASHBOARDING__________________________________________________________

Washboarding is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is approximately  6—8 in. (15—20 cm). Color variation (light-to-dark) may also be noticed.

This condition is usually caused by a rocking motion in the cutting unit(s). This condition is found mostly on mowers with multiple (suspended) cutting units, but other causes can produce the same result.

Washboarding may also be caused by variations in the turf.

NOTE: Arrow indicates direction of travel.

Probable Cause Remedy

Mowing (ground) speed is too fast. Reduce mowing (ground) speed.

Grass build-up on roller. Clean the roller and use scrapers or brushes.

Roller is out of round. Replace roller.

Mowing in the same direction. Change mowing direction regularly.

Use of a groomer on cleanup pass. Groomers should be used only in a straight line.

11 QUALITY OF CUT

TN0220

11.3 MARCELLING_____________________________________________________________

Marcelling, like washboarding, is a cyclical pattern of varying cutting heights, resulting in a wave-like cut appearance. In most cases, the wave tip-to-tip distance is 2 in. (5 cm) or less.

NOTE: Arrow indicates direction of travel.

Probable Cause Remedy

Mowing (ground) speed is too fast. Reduce mowing (ground) speed.

HOC (height-of-cut) setting is too low for turf conditions.

Cutting reel diameter is worn. Check cutting reel diameter and replace if worn.

Check/adjust HOC to turf conditions.

QUALITY OF CUT 11

TN0221

11.4 STEP CUTTING____________________________________________________________

Step cutting occurs when grass is cut taller on one side of a reel than the other or one cutting unit to another. This is usually caused by mechanical wear or an incorrect roller or HOC (height-of-cut) adjustment.

NOTE: Arrow indicates direction of travel.

Probable Cause Remedy

HOC (height-of-cut) settings are different from one side of a reel to the other or from one cutting unit to another.

Worn front roller bearings. Check/replace front roller bearings.

Reel-to-bedknife contact is different from one side of the cutting unit to the other or from one cutting unit to another.

Cutting reel movement is restricted. Check/remove cutting reel movement obstruction.

Variations in turf density. Change mowing direction.

Machine weight distribution is uneven. Check/adjust tire inflation pressure.

Check HOC adjustment of cutting units.

Check reel-to-bedknife contact.

11 QUALITY OF CUT

TN0222

11.5 SCALPING _______________________________________________________________

Scalping is a condition in which areas of grass are cut noticeably shorter than the surrounding areas, resulting in a light green or even brown patch. This is usually caused by an excessively low height-of-cut (HOC) setting and/or uneven turf.

NOTE: Arrow indicates direction of travel.

Probable Cause Remedy

HOC (height-of-cut) settings are lower than normal. Check/adjust the HOC settings.

Improper reel-to-bedknife adjustment. Adjust reel-to-bedknife setting for desired HOC.

Turf too uneven for the mower to follow. Change mowing direction.

Cutting too much grass at one time. Mow more often.

Mowing (ground) speed is too fast. Reduce mowing (ground) speed.

QUALITY OF CUT 11

TN0223

11.6 STRAGGLERS ____________________________________________________________

Stragglers are scattered blades of uncut or poorly cut grass.
