OPERATION

Safe Operating Practices

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Safe Operation

 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 the manufacturer.

 Never leave a running mower unattended. Always stop

on level ground, disengage deck clutch, place steering control levers in park brake position, stop the engine, and remove ignition key before leaving operator’s seat for any reason. Wait for engine and all moving parts to come to a complete stop before leaving the mower for any rea son including emptying the catcher or unclogging the chute.

 Do not change the engine governor setting or overspeed

the engine. Operating the engine at excessive speed may increase the hazard of personal injury.

 Always remain seated while operating mower.  Always keep safety shields and covers in place, except

for servicing.

 Always maintain a safe distance from people and pets

when mowing. Always stop mower if someone enters the area.

 Always operate mower in daylight or with adequate

working lights.

 Follow daily and weekly checklists, making su re hoses

are tightly secured and bolts are tightened.

 Always observe traffic laws while driving mower from

one location to another. Watch for traffic when operating near or crossing roadways.

 Always be alert for hazards such as rocks, metal objects

and other debris which may be thrown or entangled by mower blades. Watch out for holes or deep depressions.

 Inspect area to be mowed for hazards such as rocks,

metal objects and other debris which may be thrown or entangled by mower blades. Remove these objects before mowing.

 Always inspect mower for damage after striking a foreign

object. If damage is found, repair mower immediately. Be sure to stop on level ground, disengage deck clutch, set park brake, stop the engine, and remove the ignition switch key when leaving the operator’s seat to inspect damage.

 Always wear adequate ear protection, such as earplugs,

when operating this equipment as prolonged exposure to uncomfortable or loud noises can cause impairment or loss of hearing. Do not wear radios or music headphones while operating the machinery. Safe operation requires your full attention.

 Do not operate the equipment while wearing sandals, ten-

nis shoes, sneakers, shorts or any type of loose fitting

clothing. Do not use a towel as a headband or neck wrap and do not hang towel from the waist. Long hair, loose clothing or jewelry may get tangled in moving parts. Always wear long pants, safety glasses, ear protection and safety shoes when operating this mower.

 Always be aware of what is behind the mower before

backing up. Never mow in reverse. Always look down and behind before and while backing up.

 Never push forward suddenly on your steering control

levers while the mower is in rearward motion because mower may tip backwards.

 Never pull back suddenly on your steering control levers

while the mower is in forward motion.

 When mowing in reverse, push forward slowly on the

steering control levers and avoid sudden movement. rapid movement of the steering control levers in either

direction could result in a reaction of the mower that can cause serious injury.

 Never operate a poorly maintained mower.  Never attempt high speed maneuvering, especially in

crowded or congested areas.

 Never allow persons to operate this mower without

proper instruction or allow children to operate mower. Allow only responsible adults who are familiar with these instructions to operate this mower.

 Never put hands or feet under any part of the mower

while it is running.

 Never carry passengers.  Never direct discharged material toward anyone. Avoid

discharging material against a wall or obstruction. Mate rial may ricochet back towards the operator. Always disengage the mower blades and wait for them to stop before crossing gravel drives, walks or roads.

 Always keep clear of the mower blades and attachments

during their operation.

 Do not use any unauthorized attachment or modify the

mower.

 Turn off mower blades when not mowing.  Slow down before turning.  Stop the engine before removing the grass catcher or

unclogging the discharge chute. Never clear the discharge chute with the engine running. Turn off the engine and be sure the blades have stopped before cleaning. Use a stick to clear a plugged discharge area. Never use your hand!

 Do not operate the mower if you are fatigued, sick or

while under the influence of alcohol or drugs, if your are pregnant or under 18 years old.

 Exercise caution when loading or unloading the mower

onto a trailer or truck.

 Always wear safety goggles or safety glasses with side

shields when operating the mower.

 Data indicates that operators, age 60 years and above, are

involved in a large percentage of riding mower-related injuries. These operators should evaluate their ability to operate the mower safely enough to protect themselves and others from serious injury.

603744_0911 3-1

 Follow the manufacturer’s recommendation for wheel

weights or counterweights.

 If any attachment or additional weight is mounted on the

rear of the unit, any rapid movement of the control levers in either direction could result in a reaction of the mower that can cause serious injury.

 Clean flammable material from mower. Prevent fires

by keeping engine compartment, top of deck, exhaust area, battery, fuel line, fuel tank and operator’s sta tion clean of accumulated trash, grass clippings, and other debris. Always clean up spilled fuel and oil.

 Always secure the ROPS in the raised position and

buckle seat belt before starting mower.

Using a Ramp

 Use extreme caution when loading and unloading a

mower onto a truck or trailer with a ramp.

 Use only a single, full width ramp; do not use individual

ramps for each side of the unit. Having a full width ramp provides a surface for the mower frame to contact if the unit starts to tip backwards. It also reduces the risk of a wheel going off and the mower tipping over.

 Do not exceed a 15 degree angle between the ramp and

the ground or between the ramp and the trailer or truck.

 When on a ramp avoid sudden acceleration

Slope Operation

Slopes are a major factor in loss-of-control and tip-over

accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back the mower up the slope or if you feel uneasy on the slope; do not mow it. REMINDER: Only operate on slopes of 15 degrees or less.

 Use extreme caution when operating on slopes.

• Be extremely careful changing directions on a slope. Slow down.

• Do not operate where the mower could slip or tip.

• Turn slowly

• Turn on the most level part of the slope

• To maximize traction, it is better to turn the front of the mower uphill, rather than downhill. If drive

tires lose traction, steering control is lost which could cause serious injury or death.

• If it becomes necessary to turn downhill, turn slowly and gradually, if possible.

 Do not remove or modify the stabilizer wheels.  Watch for holes, ruts, bumps, rocks or other hidden

objects. Uneven terrain could overturn the mower. Tall grass can hide obstacles.

 Remove obstacles such as rocks, tree limbs, etc.  Keep all movement on slopes slow and gradual. Do not

make sudden changes in speed or direction.

 Avoid starting and stopping on a slope. If t ires lose trac-

tion, disengage the mower blades and proceed slowly straight down the slope.

 Mow a safe distance (minimum of 10 feet) away from

drop-offs, retaining walls, drainage ditches, embank ments, water, and other types of hazards to avoid a wheel dropping over the edge or to avoid the ground from

breaking away. This will reduce the risk of the mower suddenly rolling over causing serious injury or death.

 Use a walk behind, push mower or hand-held trimmer on

slopes and near drop-offs, retaining walls, drainage ditches, embankments and water to avoid mower rollover and serious injury or death.

 Do not mow on wet grass. Slippery conditions reduce

traction which could cause sliding and loss of control.

 Do not tow on slopes. The weight of the towed equip-

ment may cause loss of traction and loss of control.

 Do not try to stabilize the mower by putting your foot on

the ground.

 If the mower’s tires lose traction when operating on

slopes, disengage the blades, place the control levers in the park brake position, stop the engine, remove ignition switch key, and get help.

 Never make sudden starts, stops, turns, or reverse direc-

tion, especially when maneuvering on slopes. The steering is designed for sensitive response. Rapid movement of the control levers in either direction could result in a reaction of the mower that can cause serious injury.

 Never stop suddenly while backing down slopes. This

action may result in a reaction of the mower that can cause serious physical injury.

 The BigDog® mower is capable of operating horizontally

(traverse) on moderately steep slopes. When operating on slopes up to 15 degrees, be aware of any conditions that may cause the mower drive tires to lose traction resulting in a possible loss of control of the mower. An operator should not operate on a slope until he is thoroughly familiar with the equipment.

Do not operate on slopes greater than 15 degrees.

Refer to the Slope Guide, when determining the degree of slope to be mowed. It is strongly recommended that the operator drive the mower off of the slope, using extreme caution, if any sign of loss of traction is detected. Wait until the condition that caused the problem is resolved before attempting to operate on the slope again. T errain conditions can affect traction resulting in possible loss of control of the mower. Some of the conditions to be aware of are:

1.Wet terrain

2.Depressions in the ground; i.e. holes, ruts, washouts

3.Mounds of dirt

4.Soil type; i.e. sand, loose dirt, gravel, clay

5.Grass type, density, and height

6.Extremely dry conditions of grass

7.Tire pressure The attachments mounted to the mower will also affect the way it handles on a slope. Be aware that each attach ment’s characteristics vary. Do not tow on slopes. The weight of the towed equipment may cause loss of traction and loss of steering control. Another consideration to safe mowing on slopes is to be aware of what is located at the bottom of the slope. Extreme caution should be used when there is a hazard located at the bottom of the slope. Some examples are:

1.Water; i.e. lake, river

3-2 603744_0911

2.Cliffs, retaining walls

3.Roads, highways

4.Buildings

5.Rocks These are just a few examples of situations when caution must be used when operating on a slope. There are many other possibilities too numerous to mention. Just reme m ber to always exercise extreme caution when operating on any slope.

 The ROPS will minimize chance of injury or death from

rollover. Seat belt must be fastened while operating a mower equipped with ROPS in the raised and secured

position. Both retaining pins and hair pins must be installed. Failure to use seat belt will result in serious

injury in the event of a roll over.

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower and the mowing activity. Never assume that children will remain where you last saw them.

 Never leave mower unattended with ignition key in

switch, especially with children present.

 Children or bystanders may be injured if they move or

attempt to operate the mower while it is unattended. Always disengage deck clutch, place control levers in park brake position, stop the engine, and remove ignition key when leaving operator’s seat.

 Keep children out of the mowing area and under the

watchful care of a responsible adult other than the opera

tor.

 Be alert and turn the mower off if children enter the area.  Before and while backing, look behind and down for

small children.

 Never carry children, even with the blades off. They may

fall off and be seriously injured or interfere with safe mower operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the mower.

 Never allow children to operate the mower.  Never allow children or others in or on towed equipment.  Use care when approaching blind corners, shrubs, trees,

the end of a fence or other objects that may obscure vision.

WARNING

WARNING DANGER

Prior to operating the mower the operator should be thoroughly familiar with the proper use and operation of the

pment, should read the manual completely and thor-

equi oughly, and should have attempted slow moving maneuvers to become familiar with the operation of the

pment before attempting normal speed operation. An

equi inexperienced operator should not mow on slopes or on uneven terrain.

If you lose steering control while operating the machine, place the steering control levers in the park brake position immediately. Inspect the machine and involve your BigDog problem before continuing to operate.

The unit’s steering control levers are very responsive: Easy does it! For smooth operation, move lever slowly, avoid sudden movement. Skill and ease of operation come with practice and experience. The machine can spin very rapidly. Use caution when making turns and slow down before making sharp turns.

Inexperienced operators may have a tendency to oversteer

lose control. Slow-moving practice maneuvers are recommended to become familiar with these characteristics before attempting normal speed operation.

Sharp depressions or raised obstacles (such as gutters or curbs) should not be directly approached at high speed in an attempt to “jump” them as the operator could be thrown from the equipment. Approach at a slow speed and angle one drive wheel at the obstruction. Continue at an angle until the wheel clears and then pivot the opposite wheel around.

When turning on soft wet turf, keep both wheels rolling either

forward or backward. Pivoting on one stopped wheel can damage turf. This is especially important when mowing.

Mower performance is maximum when the throttle is set at

ull rpm. This gives maximum power to the drive wheels and

f deck when needed. Use the control levers to control ground speed rather than engine rpm.

Keep blades sharp. Many

have additional sets of blades and change blades twice a day:

and

once in the morning and again at noon. Many problems with incorrect cutting patterns are due to dull blades or blades which have been sharpened incorrectly. Information on sharpening blades is listed in this manual’s maintenance section. In addition, most communities have individuals or companies which specialize in sharpening mower blades. Blade sharpness

should be checked daily.

Never work with blades while engine is running or deck clutch switch is engaged (on). Always place deck clutch switch in the disengaged position, place steering control levers in the park brake position and turn en gine off and disconnect negative battery cable. Block up mower when you must work under it. Wear gloves when handling blades. Always check for blade damage if mower strikes rock, branch or other foreign object during mow ing!

Use high blade speed. Y

full throttle. The throttle setting directly controls blade speed. The highest blade speed generally gives best cut.

Direct grass discharge to right, away from

Select a mowing pattern that directs grass discharge towards the outside, not towards center, of mowing area. Generally, this means using a pattern utilizing left turns because side discharge is to right. In any case, avoid throwing grass discharge onto unmowed area because grass is then mowed “twice”. Mowing twice puts an unnecessary load on the unit and reduces mowing efficiency.

When mowing a lawn for the first time

longer than normal to avoid scalping uneven terrain. When possible, it is best to use the cutting height that was used in the past. When cutting grass taller than six inches, you may want to mow the lawn twice to achieve a better quality of cut.

During normal mowing cut only about 1/3 of the grass

Alternate mowing direction to keep th

straight and better dispersion of the clippings.

Remember, grass grows at different rates at dif

of the year. Mow more often in the early spring to maintain the same cutting height. As the growth rate slows i n mid summer, mow less frequently. If you cannot mow at a regular interval, mow at a high cutting height; then mow again two days later at a lower cutting height.

Raise the cutting height of the mower if the cu

the mower is wider than the previous mower. This ensures that uneven turf is not cut too short.

Raise the cutting height

MAINTENANCE & ADJUSTMENTS

Safe servicing practices

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Service precautions

 Unless specifically required, DO NOT have engine run-

ning when servicing or making adjustments to mower. Park the machine on level ground. Place steering control levers in the park brake position, disengage deck clutch, lower deck, remove ignition switch key and disconnect negative battery cable before doing any maintenance. Wait for all movement to stop before adjusting, cleaning or repairing. Repairs or maintenance requiring engine power should be performed by trained maintenance per sonnel only. To prevent carbon monoxide poisoning, be sure proper ventilation is available when engine must be operated in an enclosed area. Read and observe safety warnings in front of manual.

 Before working on or under the deck, make certain

engine cannot be accidentally started. Shut engine off, remove ignition switch key and disconnect negative bat tery cable for maximum safety. Repairs or maintenance requiring engine power should be performed by trained maintenance personnel only.

 Except when changing or checking belt, always keep belt

covers on mower deck for safety as well as cleanliness.

 Use a stick or similar instrument to clean under the

mower making sure that no part of the body, especially arms and hands are under mower.

 Keep your machine clean and remove any deposits of

trash and clippings, which can cause engine fires and hydraulic overheating as well as excessive belt wear. Clean up oil or fuel spillage. Allow machine to cool before storing.

 Clean flammable material from machine. Prevent

fires by keeping engine compartment, top of deck, exhaust area, battery, fuel line, fuel tank and opera tor’s station clean of accumulated trash, grass clippings, and other debris. Always clean up spilled fuel and oil.

 Always wear adequate eye protection when servicing the

hydraulic system and battery, or when grinding mower blades and removing accumulated debris.

 Use extra caution when handling gasoline and other

fuels. They are flammable and vapors are explosive.

 Never attempt to start engine when there is a strong odor

of gasoline fumes present. Locate and correct cause.

 Never remove the fuel cap or refuel mower while engine

is running; never refuel near an open flame or near devices which can create a spark. Refuel outdoors. Never refuel or drain the fuel from the machine indoors.

 Never run the engine in an enclosed area unless exhaust

is vented to the outside. Exhaust gases contain carbon monoxide which is odorless and deadly poison.

 Never attempt to make any adjustments or repairs to the

mower drive system, mower deck or any attachment while the mower engine is running or deck clutch is engaged. Repairs or maintenance requiring engine power should be performed by trained maintenance personnel only.

 Never work under the machine or attachment unless it is

safely supported with jack stands. Make certain machine is secure when it is raised and placed on the jack stands. The jack stands should not allow the machine to move when the engine is running and the drive wheels are rotating. Use only certified jack stands. Use only appro priate jack stands, with a minimum weight rating of 2000 pounds (907 kg) to block the unit up. Use in pairs only. Follow the instructions supplied with the vehicle stands.

 Do not touch hot parts of machine.  Keep nuts and bolts tight, especially the blade attachment

bolts. Keep equipment in good working condition.

 Never tamper with safety devices. Check their proper

operation regularly.

 Stop the engine before removing the grass catcher or

 Grass collection system components are subject to wear,

damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace with manufacturer’s recom mended parts, when necessary.

 Exercise caution when working under the deck as the

mower blades are extremely sharp. Wrap the blade(s) or wear gloves and use extra caution when servicing them.

Use only genuine BigDog® Mowers replacement parts to

ensure that original standards are maintained.

Service introduction

Regular maintenance is the best prevention for costly

downtime or expensive, premature repair. The following pages

contain suggested maintenance information and schedules which the operator should follow on a routine basis. For more detailed information order the correct Parts Manual and General Service Manual for your unit. Refer to the Product Literature section of this manual.

Remain alert for unusual noises, they could be signaling a problem. Visually inspe ct the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service. Correcting the problem as quickly as possible is the best insurance.

Clear away heavy build-up of grease, oil and dirt, especially in the engine and under the seat platform areas; minute dust particle are abrasive to close-tolerance engine and hydraulic assemblies.

Inspect mower daily for grass clippings and wire and string tangles. The underside of the mower deck will collect a build-up of grass clippings and dirt, especially when grass is wet or has

General engine maintenance

Detailed instructions and recommendations for break-in and regular maintenance are specified in the Engine Owner’s Manual. Please refer to this manual for engine servicing, lubricating oil levels with quality and viscosity recommendations, bolt torques, etc. The engine warranty is backed by the manufacturer. Special attention should be paid to applicable data which will not be duplicated here.

Fuel evaporation system filter

All BigDog® A Series mowers have a fuel evaporation system filter. This filter must be checked and replaced every 300 hours or annually whichever comes first. Figure 4-6

Belts

Inspect belts frequently for wear and serviceability. Replace a belt that shows signs of severe cuts, tears, separation, weather checking and cracking, or burns caused by slipping. Slight raveling of belt covering does not indicate failure, trim ravelings with a sharp knife.

Mower blade maintenance

Check the mower blades daily, they are the key to power efficiency and well groomed turf. Keep them sharp, a dull blade will tear rather than cut the grass, leaving a brown ragged top on the grass within a few hours. A dull blade also requires more power from the engine.

Replace any blade which is bent, cracked

or broken.

Spin the blade slowly, blade should not wobble. If blade is out of balance, true it up before reinstalling.

Lay the blade on a flat surface

Never attempt to straighten a bent blade by heating, or weld a cracked or broken blade as the blade may break and cause serious injury. Replace worn or damaged blades.

Never work with blades while engine is running or deck clutch switch is engaged (on). Always place deck clutch switch in the disengaged position, place steering control levers in the park brake position and turn engine off and disconnect negative battery cable. Block up mower when you must work under it. Wear gloves when handling blades. Always check for blade damage if mower strikes rock, branch or other foreign object during mow ing!

Always wear adequate eye protection when grinding mower blades.

Failure to correctly torque the bolt may result in the loss of the blade which can cause serious injury.

Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves and use extra caution when servicing them.

Mower blade removal

Use a 15/16” wrench to remove the 5/8” cap screw holding

the blade to the spindle shaft from underneath. NOTE: A blade

holding tool (part number 381442) is available from BigDog Mowers. It is designed to prevent the blades from rotating when they are being removed or installed on the spindle. Contact your BigDog

(Figure 4-7). Touch-up sharpening can be done with a file

com supply stores, or balancing can be done by placing the blade on an inverted line punch or 5/8” bolt. Blade should not lean or tilt.
