Safety Section 1-2

SAFETY

Engine Exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the state of California to cause cancer and birth defects or other reproductive harm.

(SG-30)

Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer, birth defects or other reproductive harm.

(SG-31)

Operator Safety Instructions and Practices

The rotating parts of this machine continue to rotate even after the PTO has been turned off.

The operator should remain in his seat for 60 seconds after the brake has been set, the

PTO disengaged, the tractor turned off, and all evidence of rotation has ceased.

(S3PT-10)

“Wait a minute...Save a life!”

Never crawl under a raised Implement supported solely by the Tractor 3-Point hitch.

Release of the control lever or mechanical failure will result in the Implement falling and possible injury or death. Always securely block up the Implement before crawling underneath to perform repairs and service.

(S3PT-19)

Never operate the Tractor or Implement until you have read and completely understand this Manual, the Tractor Operator’s Manual, and each of the Safety Messages found in the Manual or on the Tractor and

Implement. Learn how to stop the tractor engine suddenly in an emergency. Never allow inexperienced or untrained personnel to operate the Tractor or Implement without supervision. Make sure the operator has fully read and understood the manuals prior to operation.

(SG-4)

The operator and all support personnel should wear hard hats, safety shoes, safety glasses, and proper hearing protection at all times for protection from injury including injury from items that may be thrown by the equipment.

(SG-16)

Safety Section 1-3

SAFETY

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE

PERMANENT HEARING LOSS! Tractors with or without an Implement attached can often be noisy enough to cause permanent hearing loss.

We recommend that you always wear hearing protection if the noise in the Operator’s position exceeds 80db. Noise over 85db over an extended period of time will cause severe hearing loss. Noise over 90db adjacent to the Operator over an extended period of time will cause permanent or total hearing loss. NOTE: Hearing loss from loud noise

[from tractors, chain saws, radios, and other such sources close to the

ear] is cumulative over a lifetime without hope of natural recovery.

(SG-I7)

Always read carefully and comply fully with the manufacturer’s instructions when handling oil, solvents, cleansers, and any other chemical agent.

(SG-22)

KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement and possible serious injury or death.

(SG-24)

Never allow children to play on or around Tractor or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others.

(SG-25)

NEVER use drugs or alcohol immediately before or while operating the

Tractor and Implement. Drugs and alcohol will affect an operator’s alertness and coordination and therefore affect the operator’s ability to operate the equipment safely. Before operating the Tractor or Implement, an operator on prescription or over-the-counter medication must consult a medical professional regarding any side effects of the medication that would hinder their ability to operate the Equipment safely. NEVER knowingly allow anyone to operate this equipment when their alertness or coordination is impaired. Serious injury or death to the operator or others could result if the operator is under the influence of drugs or alcohol.

(SG-27)

Prolonged operation may cause operator boredom and fatigue affecting safe operation.

Take scheduled work breaks to help prevent these potentially impaired operating conditions. Never operate the Implement and Tractor in a fatigued or bored mental state which impairs proper and safe operation.

(SG-32)

SM72 02/10

Safety Section 1-4

SAFETY

Use extreme caution when getting onto the Implement to perform repairs, maintenance and when removing accumulated material. Only stand on solid flat surfaces to ensure good footing. Use a ladder or raised stand to access high spots which cannot be reached from ground level. Slipping and falling can cause serious injury or death.

(SG-33)

Avoid contact with hot surfaces including hydraulic oil tanks, pumps, motors, valves and hose connections. Relieve hydraulic pressure before performing maintenance or repairs.

Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding.

(SG-34)

DO NOT operate this Implement on a Tractor that is not properly maintained. Should a mechanical or Tractor control failure occur while operating, immediately shut down the

Tractor and perform repairs before resuming operation. Serious injury and possible death could occur from not maintaining this Implement and Tractor in good operating condition.

(SG-36)

Avoid contact with hot surfaces of the engine or muffler. Use gloves and eye protection when servicing hot components. Contact with a hot surface or fluid can cause serious injury from burns or scalding.

(SG-38)

Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.

(SGM-09)

Always keep a careful lookout and use extreme care when working around utility and municipal obstructions. Never allow the Mower to contact any utility, municipal, or other type structure. Clearly mark all mowing obstructions and consult local utility providers for a safe code of operation.

(SPU-5)

Do not operate the implement while wearing loose fitting clothing. Entanglement of the clothing with the rotating elements can result in serious injury or even death. Stay clear of all rotating elements at all times.

(SSP-03)

Equipment Operation Safety Instructions and Practices

Never leave the Tractor and Implement unattended while the Implement is in the lifted position. Accidental operation of lifting lever or a hydraulic failure may cause sudden drop of unit with injury or death by crushing. To properly park the implement when disconnecting it from the tractor, lower the stand and put the retaining pin securely in place, or put a secure support under the A-Frame. Lower the implement carefully to the ground. Do not put hands or feet under lifted components.

(S3PT-1)

SM72 02/10

Safety Section 1-5

SAFETY

Use extreme care when lowering or unfolding the implement’s wings. Make sure no bystanders are close by or underneath the wings. Allow ample clearance around the implement when folding or unfolding the wings. Use extreme caution around buildings or overhead power lines.

(S3PT-05)

This Implement may be wider than the Tractor. Be careful when operating or transporting this equipment to prevent the Implement from running into or striking sign posts, guard rails, concrete abutments or other solid objects. Such an impact could cause the Implement and

Tractor to pivot violently resulting in loss of steering control, serious injury, or even death.

Never allow the Implement to contact obstacles.

(S3PT-12)

Be sure you have adequate knowledge of the property you will be working on. Take time to make yourself aware of any area underground lines or cables. Contact with buried lines or cable could result in serious injury or death. If in doubt about buried utility lines call 811 before digging or 1-800-258-0808.

(SBH-6)

Do not operate Mower if excessive vibration exists. Shut down PTO and the Tractor engine. Inspect the Mower to determine the source of the vibration. If Mower blades are missing or damaged replace them immediately. Do not operate the mower until the blades have been replaced and the Mower operates smoothly. Operating the Mower with excessive vibration can result in component failure and broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the Mower to be operated with blades missing.

(SFL-4)

Operate this Equipment only with a Tractor equipped with an approved rollover-protective system (ROPS). Always wear seat belts. Serious injury or even death could result from falling off the tractor--particularly during a turnover when the operator could be pinned under the ROPS.

(SG-7)

BEFORE leaving the tractor seat, always set the parking brake and/or set the tractor transmission in parking gear, disengage the PTO, stop the engine, remove the key, and wait for all moving parts to stop. Place the tractor shift lever into a low range or parking gear to prevent the tractor from rolling. Never dismount a Tractor that is moving or while the engine is running. Operate the Tractor controls from the tractor seat only.

(SG-9)

Never allow children or other persons to ride on the Tractor or Implement.

Falling off can result in serious injury or death.

(SG-10)

SM72 02/10

Safety Section 1-6

SAFETY

Never allow children to operate, ride on, or come close to the Tractor or

Implement. Usually, 16-17 year-old children who are mature and responsible can operate the implement with adult supervision, if they have read and understand the Operator’s Manuals, been trained in proper operation of the tractor and Implement, and are physically large enough to reach and operate the controls easily.

(SG-11)

Do not mount or dismount the Tractor while the tractor is moving. Mount the Tractor only when the Tractor and all moving parts are completely stopped.

(SG-12)

Start tractor only when properly seated in the Tractor seat. Starting a tractor in gear can result in injury or death. Read the Tractor operators manual for proper starting instructions.

(SG-13)

Do not operate this Equipment with hydraulic oil or fuel leaking. Oil and fuel are explosive and their presence could present a hazard. Do not check for leaks with your hand! High-pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. To check for a hose leak, SHUT the unit ENGINE

OFF and remove all hydraulic pressure. Wear oil impenetrable gloves, safety glasses and use Cardboard to check for evidence of oil leaks. If you suspect a leak, REMOVE the HOSE and have it tested at a Dealer.

If oil does penetrate the skin, have the injury treated immediately by a physician knowledgeable and skilled in this procedure.

(SG-15)

Never run the Tractor engine in a closed building or without adequate ventilation. The exhaust fumes can be hazardous to your health.

(SG-23)

Do not exceed the rated PTO speed for the Implement. Excessive PTO speeds can cause

Implement driveline or blade failures resulting in serious injury or death.

(SG-26)

SM72 02/10

© 2010 Alamo Group Inc.

Safety Section 1-7

SAFETY

Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat with the seat belt securely fastened around you. Inadvertent movement of the Tractor or

Implement may cause serious injury or death.

(SG-29)

In case of mechanical difficulty during operation, place the transmission in the park position, set the parking brake, shut down all power, including the PTO and the engine and remove the key. Wait until all rotating motion has stopped before dismounting.

(SG-39)

Do Not operate this equipment in areas where insects such as bees may attack you and/or cause you to lose control of the equipment. If you must enter in such areas, use a tractor with an enclosed Cab and close the windows to prevent insects from entering. If a tractor cab is not available, wear suitable clothing including head, face, and hand protection to shield you from the insects. Attacking insects can cause you to lose control of the tractor, which can result in serious injury or death to you or bystanders. Never dismount a moving tractor.

(SG-40)

Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least

300 feet (90 m) in front and to the sides of the tractor and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these type of items discontinue mowing.

(SGM-1)

There are obvious and hidden potential hazards in the operation of this

Mower. REMEMBER! This machine is often operated in heavy brush and in heavy weeds. The Blades of this Mower can throw objects if shields are not properly installed and maintained. Serious injury or even death may occur unless care is taken to insure the safety of the operator, bystanders, or passersby in the area. Do not operate this machine with anyone in the immediate area. Stop mowing if anyone is within 300 feet of mower.

(SGM-02)

The rotating parts of this machine have been designed and tested for rugged use.

However, the blades could fail upon impact with heavy, solid objects such as metal guard rails and concrete structures. Such impact could cause the broken objects to be thrown outward at very high velocities. To reduce the possibility of property damage, serious injury, or even death, never allow the cutting blades to contact such obstacles.

(SGM-4)

SM72 02/10

© 2010 Alamo Group Inc.

Safety Section 1-8

SAFETY

Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.

Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing.

(SGM-05)

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

(SGM-06)

Mow at the speed that you can safely operate and control the tractor and mower. The correct mowing speed depends on terrain condition and grass type, density, and height of cut. Normal ground speed range is from 2 to 5 mph(3-8 kph). Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided.

(SGM-07)

Avoid mowing in reverse direction when possible. Check to make sure there are no persons behind the mower and use extreme care when mowing in reverse. Mow only at a slow ground speed where you can safely operate and control the tractor and mower.

Never mow an area that you have not inspected and removed debris or foreign material.

(SGM-08)

Do not mow with two machines in the same area except with Cab tractors with the windows closed.

(SGM-11)

SM72 02/10

Safety Section 1-9

SAFETY

Follow these guidelines to reduce the risk of equipment and grass fires while operating, servicing, and repairing the Mower and Tractor:

-Equip the Tractor with a fire extinguisher in an accesible location.

-Do Not operate the Mower on a Tractor with an underframe exhaust.

-Do Not smoke or have an open flame near the Mower and Tractor.

-Do Not drive into burning debris or freshly burnt areas.

-Ensure slip clutches are properly adjusted to prevent excessive slippage and plate heating.

-Never allow clippings or debris to collect near drivelines, slip clutches, and gearboxes.

Periodically shut down the Tractor and Mower and clean clippings and collected debris from the mower deck.

(SGM-12)

The Mower is designed for certain mowing applications and is rated to cut up to a specific size vegetation (see Mower Standard Equipment and Specifications). DO NOT use this mower to cut vegetation above the Mower’s rated capacity or to cut any type of nonvegetative material. Only operate this Mower on a properly sized and equipped Tractor.

Operating this Mower in an application for which it is not designed and/or operating the

Mower with the wrong size Tractor can cause Mower component damage and equipment failure resulting in possible serious injury or death.

(SGM-14)

Do not operate or pull the mower into standing water. When uplift or fan type mower blades contact water they can be severely deflected downward causing possible failure of blade resulting in serious boldly injury to the operator or bystanders.

(SGM-15)

Use extreme caution when raising the Mower above ground level. Stop the Blades from turning when the Mower is raised and passersby are within 100 yards. Raising the

Mower exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades.

(SPU-1)

SM72 02/10

© 2010 Alamo Group Inc.

Safety Section 1-10

SAFETY

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:

-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;

-Mower sections or Wings are running close to and parallel to the ground without exposed

Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and

make the final cut more uniform).

(SRM-01)

Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline which will cause accelerated wear and breakage of drive train components and could result in possible injury from the separated Driveline sections.

(SRM-04)

Do not let the Blades turn when the Mower Deck is raised for any reason, including clearance or for turning. Raising the Mower deck exposes the Cutting Blades which creates a potentially serious hazard and could cause serious injury or even death from objects thrown from the Blades.

(SRM-07)

Connecting or Disconnecting Implement Safety Instructions and

Practices

DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor

PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can result from using a PTO adapter. Consult an authorized dealer for assistance if the Implement driveline does not match the Tractor PTO.

(S3PT-14)

SM72 02/10

© 2010 Alamo Group Inc.

Safety Section 1-11

SAFETY

Always shut the Tractor completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Tractor hitches.

(S3PT-15)

Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission. Tractor braking distances can be substantially increased by the momentum of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has been disengaged. Install an over running clutch between the Tractor

PTO and the Mower driveline to prevent this potentially dangerous situation.

(S3PT-16)

When attaching the Implement input driveline to the Tractor PTO, it is important that the connecting yoke spring activated locking collar slides freely and the locking balls are seated securely in the groove on the Tractor PTO shaft. Push and pull the driveline back and forth several times to ensure it is securely attached. A driveline not attached correctly to the

Tractor PTO shaft could come loose and result in personal injury and damage to the

Implement.

(S3PT-17)

Before operating the Implement, check to make sure the Implement input driveline will not bottom out or become disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious damage to the Tractor PTO by pushing the PTO into the Tractor and through the support bearings or downward onto the PTO shaft, breaking it off. A broken driveline can cause personal injury.

(S3PT-18)

Transporting Safety Instructions and Practices

Be particularly careful when transporting the Implement with the Tractor. Turn curves or go up hills only at a low speed and using a gradual steering angle. Rear mounted implements move the center of gravity to the rear and remove weight from the front wheels. Make certain, by adding front ballast, that at least 20% of the tractor’s weight is on the front wheels to prevent rearing up, loss of steering control or Tractor tip-over. Slow down on rough or uneven surfaces to prevent loss of steering control which could result in property damage or possible injury. Do not transport unless 3-Point lift lever is fully raised and in the latched transport position. Dropping implement in transport can cause serious damage to the tractor and/or Implement and possibly cause the operator or others to be injured or killed.

(S3PT-02)

Allow sufficient clearance for the Implement to swing outward while turning. Implements carried behind the Tractor will swing outside the tire path when making turns. Contacting a solid object while turning will cause equipment damage and possible injury.

(S3PT-20)

SM72 02/10

© 2010 Alamo Group Inc.

Safety Section 1-12

SAFETY

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the

Equipment use the Tractor flashing warning lights and follow all local traffic regulations.

(SG-6)

Transport only at speeds where you can maintain control of the equipment. Serious accidents and injuries can result from operating this equipment at high speeds. Understand the Tractor and Implement and how it handles before transporting on streets and highways. Make sure the Tractor steering and brakes are in good condition and operate properly.

Before transporting the Tractor and Implement, determine the proper transport speeds for you and the equipment. Make sure you abide by the following rules:

Test the tractor at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Tractor and Implement. As you increase the speed of the Tractor the stopping distance increases. Determine the maximum transport speed not to exceed 20 mph (30 kph) for transporting this equipment.

Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that the equipment can be operated at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum turning speed for you and this equipment before operating on roads or uneven ground.

Only transport the Tractor and Implement at the speeds which allow you to properly control the equipment.

Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes or worn tires. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.

(SG-19)

Be particularly careful when transporting the Implement using the tractor. Turn curves or go up or down hills only at a low speed and at a gradual steering angle. Make certain that at least 20% of the tractor’s weight is on the front wheels to maintain safe steerage. Slow down on rough or uneven surfaces.

(STI-01)

Only tow the Implement behind a properly sized and equipped Tractor which exceeds the weight of the Implement by at least 20%. DO NOT tow the Implement behind a truck or other type of vehicle. Never tow the

Implement and another Implement connected in tandem. Never tow the

Implement at speeds over 20 MPH.

8. DRIVING THE SKID STEER AND MOWER

Safe skid steer transport requires the operator to possess a thorough knowledge of the model being operated and precautions to take while driving with a front attachment. Ensure the skid steer has the capacity to handle the weight of the mower and the skid steer operating controls are set for safe transport. OPS-SS-0021

Unit and Implement and how it handles before transporting on streets and highways. Make sure the Power Unit steering and brakes are in good condition and operate properly.

Transport only at safe speeds. Serious accidents and injuries can result from operating this equipment at unsafe speeds. Understand the Power

Before transporting the Power Unit and Implement, determine the safe transport speeds for you and the equipment. Make sure you abide by the following rules:

• Test the Power Unit at a slow speed and increase the speed slowly. Apply the Brakes smoothly to determine the stopping characteristics of the Power Unit and Implement.

As you increase the speed of the Power Unit the stopping distance increases.

Determine the maximum safe transport speed for you and this Equipment.

• Test the equipment at a slow speed in turns. Increase the speed through the turn only after you determine that it is safe to operate at a higher speed. Use extreme care and reduce your speed when turning sharply to prevent the tractor and implement from turning over. Determine the maximum safe turning speed for you and this equipment before operating on roads or uneven ground.

• Only transport the Power Unit and Implement at the speeds that you have determined are safe and which allow you to properly control the equipment.

Be aware of the operating conditions. Do not operate the Power Unit with weak or faulty brakes. When operating down a hill or on wet or rain slick roads, the braking distance increases: use extreme care and reduce your speed. When operating in traffic always use the Power Unit's flashing warning lights and reduce your speed. Be aware of traffic around you and watch out for the other guy.

OPERATION

8.1 Starting the Skid Steer

Refer to the skid steer operator’s manual for proper starting procedures. Consult an authorized dealer if the starting procedure is unclear. Make sure that the skid steer parking brake is set, its transmission is in neutral, the mower is lowered to the ground, and the auxiliary hydraulic remote lever is disengaged before starting the skid steer. Only start the skid steer when properly seated in the operator’s seat with the seat belt securely fastened. OPS-SS-0026

8.2 Driving the Skid Steer

Start off driving at a slow speed and gradually increase your speed while maintaining complete control of the skid steer and mower. Do not operate the skid steer at speeds that cannot be safely handled or which will prevent stopping quickly during an emergency.

Do not raise or tilt the mower to a height that obstructs the operator’s visibility to the front of the mower. The height limiting safety chain should stay connected to the mower and skid steer during transport to prevent the mower from being raised too high. OPS-SS-0027

Perform turns with the skid steer and mower at slow speeds to determine how the skid steer handles a turn. Determine the safe speed to maintain proper control of the skid steer when making turns. When turning with an attached mower, the overall working length of the unit is increased. Allow additional clearance for the mower when making turns. OPS-SS-0009

To avoid overturns, drive the skid steer with care and at safe speeds, especially when operating over rough ground, crossing ditches or slopes, and turning corners. Use extreme caution when operating on steep slopes. Travel at a slow speed when going downhill. DO NOT coast or free-wheel downhill.

When operating the tractor and mower across slopes and inclines, through ditches, and other uneven terrain conditions, it is important to maintain sufficient deck to ground clearance. Blade contact with the ground may cause soil, rocks and other debris to be thrown out from under the mower resulting in possible injury and/or property damage. Blades hitting the ground also produces a severe shock load on the mower and to the mower blades resulting in possible damage and premature wear.

Operation Section 4-22

OPERATION

9. OPERATING THE SKID STEER AND MOWER

THE OPERATOR MUST COMPLETELY UNDERSTAND HOW TO OPERATE THE SKID STEER AND

MOWER AND ALL CONTROLS BEFORE ATTEMPTING TO MOW. The operator must read and understand the Safety and Operation Sections of the mower and skid steer operator’s manuals. These manuals must be read and explained to any operator who cannot read. Never allow someone to operate the mower and skid steer without complete operating instructions.

Before starting any mowing operation, the operator must become familiar with the area to be mowed and any obstacles and hazards contained within to ensure safety to the operator, bystanders, and equipment. Special attention should be paid to foreign debris, rough terrain, steep slopes, and passersby and animals in the area.

OPS-SS-0028

Extreme care should be taken when operating near loose objects such as gravel, rocks, wire, and other debris. Inspect the area before mowing. Foreign objects should be removed from the site to prevent machine damage and/or bodily injury or even death. Any objects that cannot be removed must be clearly marked and carefully avoided by the operator. Stop mowing immediately if blades strike a foreign object.

Repair all damage and make certain rotor or blade carrier is balanced before resuming mowing.

(SGM-05)

Many varied objects, such as wire, cable, rope, or chains, can become entangled in the operating parts of the mower head. These items could then swing outside the housing at greater velocities than the blades. Such a situation is extremely hazardous and could result in serious injury or even death. Inspect the cutting area for such objects before mowing.

Remove any like object from the site. Never allow the cutting blades to contact such items.

(SGM-06)

9.1 Foreign Debris Hazards

Before mowing, inspect the area to make sure there are no foreign objects that the mower blades could hit or become entangled with. Remove all foreign objects and debris. If objects are too big to remove, mark them clearly and be sure to prevent the mower blades from contacting them.

OPS-SS-0010

SM72 02/10

© 2010 Alamo Group Inc.

Operation Section 4-23

OPERATION

If you hit a solid object or foreign debris, stop the mower and skid steer at once. Immediately idle the engine speed and disengage the auxiliary hydraulics to stop the mower blades from turning. Wait for all mower rotating motion to stop, then raise the mower and move the skid steer and implement off the object. Inspect the area and remove, or mark the location of the debris. Inspect the condition of the mower and make any needed repairs immediately. Make sure the blades are not damaged and the carrier is balanced before resuming operation.

9.2 Bystander/Passersby Precautions

If a bystander comes within 100 yards of the skid steer while the mower is being operated, stop the skid steer at once, idle the engine and stop the mower. Do not engage the mower again until all bystanders are well past the 100 yard distance. OPS-SS-0011

Rotary Mowers are capable under adverse conditions of throwing objects for great distances (300 feet or more) and causing serious injury or death. Follow safety messages carefully.

STOP MOWING IF PASSERSBY ARE WITHIN 100 YARDS UNLESS:

-Front and Rear Deflectors, Chain Guards, or Bands are installed and in good, workable condition;

-Mower sections or Wings are running close to and parallel to the ground without exposed

Blades;

-Passersby are outside the existing thrown-object zone;

-All areas have been thoroughly inspected and all foreign material such as rocks, cans, glass, and general debris has been removed.

NOTE: Where there are grass and weeds high enough to hide debris that could be struck by the blades, the area should be: inspected and large debris removed, mowed at an intermediate height, inspected, closely with any remaining debris being removed, and mowed again at desired final height. (This will also reduce power required to mow, reduce wear and tear on the Mower drivetrain, spread cut material better, reduce streaking, and

make the final cut more uniform).

(SRM-01)

9.3 Engaging the Mower

Before engaging the mower, make certain that the area is clear of bystanders and passersby. Refer to the skid steer operator’s manual to determine the procedure to engage the front auxiliary hydraulics.

If you here unusual noises or feel abnormal vibrations, disengage the mower immediately. Inspect the mower to determine the cause of the noise or vibration and repair the problem immediately. OPS-SS-0030

Use extreme caution when raising the Mower above ground level. Stop the Blades from turning when the Mower is raised and passersby are within 100 yards. Raising the

Mower exposes the Cutting Blades which creates a potentially serious hazard and can cause serious injury by objects thrown from the Blades or by contact with the Blades.

(SPU-1)

Operation Section 4-24

OPERATION

Do not put hands or feet under mower decks. Blade Contact can result in serious injury or even death. Stay away until all motion has stopped and the decks are securely blocked up.

(SGM-09)

9.4 Operating Speed and Ground Speed

Ground speed for mowing will depend upon the height, type, and density of vegetation to be cut.

Recommended speed for efficient mower performance is between 2 and 5 mph. Operate the mower at its full rated speed to maintain blade speed for a clean cut. Refer to the skid steer operator’s manual and its instrument panel for the engine speed required to provide the rated operating speed. Make sure that the mower is operating at its full rated speed before entering the vegetation to be cut. If it becomes necessary to temporarily regulate engine speed, increase or decrease the throttle gradually.

Ground speed is achieved by transmission speed and not by the engine speed. The operator may be required to experiment to determine the best travel speed which provides the best performance from the mower and most efficient skid steer operation. As the severity of cutting conditions increase, the ground speed should be decreased while maintaining the rated mower operating speed. OPS-SS-0012

The Mower shaft speed must not - UNDER ANY CIRCUMSTANCES - exceed 1150 RPM.

(SPU-7)

Mow at the speed that you can safely operate and control the Power Unit and Mower. Safe mowing speed depends on terrain condition and grass type, density, and height of cut.

Normal ground speed range is from 0 to 5 mph. Use slow mowing speeds when operating on or near steep slopes, ditches, drop-offs, overhead obstructions, power lines, or when debris and foreign objects are to be avoided.

Operation Section 4-25

OPERATION

9.5 Operating the Mower

Only operate the mower from the skid steer operator’s seat with the seatbelt securely fastened.

The mower is designed to cut vegetation up to 2” in diameter. Sharp blades will produce a cleaner cut and require less power. Travel at a speed that allows the mower sufficient time to cut through the vegetation and maintain the mower operating speed to prevent overloading the mower and skid steer. Choose a driving pattern that provides the maximum pass length and minimizes turning.

Avoid mowing in the reverse direction when possible. In situations where the mower must be backed to access areas to be cut, make sure there are no persons or other foreign debris behind the mower before mowing in reverse. When mowing in reverse, operate the skid steer and mower at a reduced ground speed to ensure skid steer and mower control is maintained. OPS-SS-0013

Mow only in conditions where you have clear visibility in daylight or with adequate artificial lighting. Never mow in darkness or foggy conditions where you cannot clearly see at least

100 yards in front and to the sides of the Power Unit and mower. Make sure that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead obstructions, power lines, debris and foreign objects. If you are unable to clearly see these types of items discontinue mowing.

(SPU-27)

Never mow in the reverse direction. The Power Unit’s operator protective structure obstructs the operator’s visibility of the unit’s path when traveling in the reverse direction.

(SPU-8)

Stay alert and watch for trees, low hanging limbs, power lines, and other overhead obstacles and solid ground objects while you are operating. Use care to avoid hitting these items.

Large, dense, or wet vegetation may need to be mowed in two or more passes to achieve a uniform cut. In such conditions, raise the cutting height up to 18” on the first pass.

Then lower the mower to the desired height and mow the vegetation a second time. If possible, select a mowing pattern that is at a 90 degree angle to the first pass to reduce streaking and provide a more even cut.

9.6 Shutting Down the Mower

To shut down the mower, first bring the skid steer to a complete stop. Then slow down the mower by reducing the engine speed before disengaging the auxiliary hydraulics.

Park the skid steer on a level surface, place the transmission in park or neutral and apply the parking brake, lower the attached mower to the ground, shut down the engine, remove the key, and wait for all motion to come to a complete stop before exiting the skid steer. OPS-SS-0031

OPERATION

10. DISCONNECTING THE MOWER FROM THE SKID STEER

Always shut the Power Unit completely down, place the transmission in park, and set the parking brake before you or anyone else attempts to connect or disconnect the Implement and Power Unit hitches.

(SPU-32)

Before disconnecting the mower, the auxiliary hydraulics must be disengaged and blade rotation at a complete stop. Lower the mower to the ground. If the mower is not resting securely on the ground, block the mower up securely before attempting to disconnect it from the skid steer hitch.

1. Completely shut down the mower and skid steer and secure the skid steer in position by applying the parking brake. Wait for all movement to come to a complete stop before exiting the skid steer. Never extend any part of your body from the operator’s area to operate latches or to disconnect hydraulic lines or the height limiting safety chain.

2. Disconnect the mower driveline from the skid steer. Lay the driveline down carefully to avoid damaging the driveline or its shield. Do not let the driveline fall into mud or dirt, which can contaminate the bearing and shorten the life of the driveline.

3. Remove the height limiting safety chain from the front of the skid steer chassis.

4. Pull the latching handles upward to release the latch pins from the mower hitch tabs.

5. Board the skid steer, fasten your seatbelt, and start the engine. Tilt the mounting plate forward and back away from the mower at the same time. The mower should be released from the skid steer at this point.

Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.

11. MOWER STORAGE

Properly preparing and storing the mower at the end of the season is critical to maintaining its appearance and to help ensure years of dependable service. The following are suggested storage procedures:

1. Thoroughly clean all debris off the mower to prevent damage from rotting grass and standing water.

2. Lubricate all mower grease points and fill spindle oil level as detailed in the maintenance section.

3. Tighten all bolts and pins to the recommended torque.

4. Check the mower for worn and damaged parts.

Perform repairs and make replacements immediately so that the mower will be ready for use at the start of the next season.

5. Store the mower in a clean, dry place with the mower housing resting securely on blocks or at ground level.

6. Keep the hydraulic hose ends from sitting in water, dirt and other contaminants. Connect the mower’s hydraulic lines together to prevent dirt and other contamination from entering the hydraulic system.

7. Use spray touch-up enamel where necessary to prevent rust and to maintain the appearance of the mower.

It is critical that the driveline clutch slip when an obstacle or heavy load is encountered to avoid mower and/or tractor damage. If the mower sits outside for an extended period of time or is exposed to rain and/or humid air, the clutch lining plates must be inspected to ensure they are not frozen together from rust or corrosion. If the mower has been exposed to such conditions, at the start of each mowing season, and any time it is suspected that the slip clutch plates may be frozen together, readjust the slip clutch as detailed in Clutch Maintenance section of this manual.

Never allow children to play on or around Power Unit or Implement. Children can slip or fall off the Equipment and be injured or killed. Children can cause the Implement to shift or fall crushing themselves or others.

12. TRANSPORTING THE SKID STEER AND MOWER

Inherent dangers of operating the skid steer and mower and the possibility of accidents are not left behind when you finish mowing an area. One must also use good judgement and safe operation practices when transporting the skid steer and mower between locations. By using good judgement and following safe transport procedures, the possibility of accidents while moving between locations can be substantially minimized. OPS-SS-0032

Never allow children or other persons to ride on the Power Unit or

Implement. Falling off can result in serious injury or death.

(SPU-16)

Before transporting the skid steer and mower, idle the skid steer engine, disengage the auxiliary hydraulics and wait for all mower moving parts to come to a complete stop. When transporting, only raise the deck enough to clear ground obstacles. Never raise the mower to a height that impairs the operator’s vision to the front of the mower.

12.1 Transporting on Public Roadways

Never allow children or other persons to ride on the Power Unit or

Implement. Falling off can result in serious injury or death.

(SPU-16)

Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in such a way as to be clearly visible and legible. When transporting the Equipment use the Power Unit flashing warning lights and follow all local traffic regulations.

(SPU-13)

Check with your local department of transportation to determine if it is legal to drive a skid steer on a public roadway. Extreme caution should be used when transporting the skid steer and mower on public roadways.

The skid steer must be equipped with all required safety warning features including a SMV emblem and flashing warning lights to alert drivers of the skid steer’s presence. Remember that roadways are primarily designed for automotive drivers and most drivers will not be looking out for you, therefore, you must look out for them. Check your side view mirrors frequently and remember that vehicles will approach quickly because of the skid steer’s slower speed. Be extremely cautious when the piece of equipment that you are towing is wider than the skid steer tire width and/or extends beyond your lane of the road.

When operating on public roads, have consideration for other road users. Pull to the side of the road occasionally to allow all following traffic to pass. Do not exceed the legal speed limit set in your country for agricultural and industrial type equipment. Always stay alert when transporting the skid steer and mower on public roads. Use caution and reduce speed if other vehicles or pedestrians are in the area.

12.2 Hauling the Skid Steer and Mower

Before transporting a loaded skid steer and mower, measure the height and width dimensions and gross weight of the complete loaded unit. Ensure that the load will be in compliance with the legal limits set for the areas that will be traveled through.

Use adequately sized and rated trailers and equipment to transport the skid steer and mower. Consult an authorized dealer to determine the proper equipment required.

Using adequately sized chains, heavy duty straps, cables and/or binders, securely tie down both the front and rear of the skid steer utilizing the proper tie down locations as specified by the skid steer manufacturer.

Arrange the chains so that when tightened, the chains are pulling downward and against themselves. Carefully tighten the securing chains or other fasteners used as much as possible using boomers or binders to apply maximum tension. Use extreme care when attaching and removing the securing devices as the extreme tension involved when released has the potential to inflict serious injury.

While hauling the skid steer and mower, make occasional stops to check that the skid steer and mower have not moved or shifted and that the securing chains have maintained tension. If during transport a hard braking, sharp turning, or swerving action was performed, stop at the next safe location to inspect the security of the load.

GEARBOX LUBRICATION

The Gearbox was filled with oil at the factory. However, it is necessary that the operator check the Geabox before operations. The oil should be to the level of the notch on the dipstick. The Filler/Breather Plug is on the top of the Gearbox. Fill through this plug using Multi-Purpose Gear Oil P/N 00786250. The oil level after operating long enough for warmed oil to flow through the Bearings into the lower Gearbox cavity. Refill to the test plug level. Check the oil again before operation, after every 40 hours of mowing, and at the beginning and end of each mowing season. The gearbox capacity is 3 quarts.

NOTE: Overfilling the Gearbox will cause pressure to build up and cause Oil Seals to leak.

ATTENTION: If the Gearbox suddenly starts making an unusual noise, stop at once, check for leaks, and refill

Geabox as required.

BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. Replace any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out when sharpening.

When sharpening blades, grind each blade the same amount to maintain balance. The difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive vibration which can damage spindle bearings. Vibration may also cause structural cracks in the mower.

Use only original equipment blades on this mower. They are made of special heat-treated alloy steel. Substitute blades may not meet specifications and may fail in a hazardous manner that could cause injury.

Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at the lower bend more than a 1/2” DEEP (due to running in gravel and/or the ground).

REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to replace such abnormally worn blades may lead to catastrophic failure of the blade and ejection of the broken part with tremendous force which may cause bodily injury or death.

NOTE: Replace Blades in pairs after no more than 1/2” notch wear!

MAINTENANCE

BLADE SHARPENING

Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,

WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR

OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLY

CAUSE SERIOUS INJURY FROM THROWN BLADES.

(SGM-10)

Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in

Image Mnt-R-0008. Always sharpen blades by grinding. DO NOT heat and pound out edge. Do not sharpen blade to a razor edge, but leave a 1/16” blunt edge. Do not sharpen back side of blade.

Avoid personal injury. Always block the mower up to prevent if from falling when the blades and/ or carrier are being serviced.

Avoid personal injury. Always wear safety glasses and face protection when grinding blades.

Maintenance Section 5-6

MAINTENANCE

BLADE CARRIER INSPECTION

Blade bolt fit into carrier bushings should be checked every time blades are changed. The blade bolt should fit into carrier bushings as a snug slip fit. If the blade bolt fit appears to be loose or sloppy, measure the square hole in bushing. If the bottom of the square hole is 1/16” or greater than the square shoulder of the new blade bolt the bushings should be replaced. Bushings can be removed by cutting bushing head where it is welded to carrier bar. Once head is removed bushing can be pressed out of bar. Clean and grind top of blade bar so new bushing can be installed and welded. Bushing should be pressed into bar as far as possible. Use low hydrogen rod to weld bushing in place.

Failure to replace a worn blade carrier bushing as described above may lead to catastrophic failure of the blade, blade bolt, and/or blade bolt nut resulting in the ejection of the broken parts out from under the mower at tremendous speed and force which could result in serious bodily injury or death.

BLADE CARRIER INSTALLATION

Clean the bore on blade carrier and surface of output shaft. Position carrier on the gearbox output shaft and install washer and slotted nut.

Tighten nut holding blade carrier to minimum 400 ft. pounds, strike the carrier near the hub several times with a heavy hammer to seat the hub. Use a suitable spacer over the nut to prevent damage to the nut and threads.

Retighten the nut to 400 ft. pounds. Install cotter pin and spread.

Always recheck spindle output shaft slotted blade carrier retaining nut torque after a few hours operation.

Operating the mower with a loose blade pan or holder can damage the taper connection on the gearbox output shaft. To ensure proper seating between the blade holder and output shaft, check and tighten the retaining nut after the first day of operation. Recheck the blade carrier attachment each morning before operating. Grasp the carrier firmly with both hands and try to push and pull the carrier with one hand while pulling and pushing with the other hand to try to rock or oscillate the blade carrier. If the carrier is loose, retighten the retaining nut before operating the mower.

Never work under the Implement, the framework, or any lifted component unless the Implement is securely supported or blocked up to prevent sudden or inadvertent falling which could cause serious injury or even death.
