Safety Rules  
General Information  
Electrical System Safety  
SERVICE AND MAINTENANCE  
• Loose connectors, worn wires, damaged wire insula-  
tion, and loose termination hardware can cause  
sparks, short-circuits, and erratic equipment opera-  
tion. Always check wiring for damage, and make  
appropriate repairs before placing unit back into oper-  
ation.  
Personal Protective Equipment  
• Wear protective safety glasses whenever using hand  
or power tools, shop equipment, and whenever work-  
ing under power equipment to protect your eyes from  
falling debris and small parts.  
• Wear safety goggles or full face protection when han-  
dling battery electrolyte fluid, or when performing  
grinding or sharpening operations that produce  
sparks or flying debris. Extensive grinding may  
require the use of protective sleeves and an apron.  
• Use care when working around exposed terminals to  
prevent short-circuiting the electrical system.  
Sparking, electric shocks, and damage to the system  
may result from accidental contact between terminals  
and metal hand tools.  
• Wear work gloves when handling sharp surfaces  
such as mower blades, or when working around  
sharp edges. Never wear gloves that are loose fitting  
or that have tie straps, as these could cause your  
hands to get caught by rotating parts, resulting in seri-  
ous injury. Chemical-resistant Rubber gloves are rec-  
ommended when handling or pouring battery elec-  
trolyte.  
Elevating Unit Safely  
• Always support unit on approved jack stands when  
working on an elevated unit, and keep unit from  
rolling by engaging parking brake and placing wheel  
chocks behind wheels still on floor or work table.  
• Secure unit to work-surface of scissor-lift worktables  
or other powered lift tables in accordance with the  
manufacturer’s instructions. Unsecured units may roll  
unexpectedly while work is being done, causing  
injuries.  
• Steel-toe safety shoes are highly recommended to  
protect feet from falling tools, heavy parts, and other  
shop equipment.  
• Never work under an elevated unit unless it is proper-  
ly supported by jack stands, locked from rolling with  
wheel chocks or equivalent, and you can quickly  
escape from under the unit in an emergency using a  
rolling device such as a mechanic’s creeper.  
Battery/Electrolyte Safety  
• Lead-Acid batteries use an electrolyte containing sul-  
phuric acid, a highly corrosive liquid that can cause  
severe chemical burns if allowed to come into contact  
with skin, or blindness if allowed to contact your eyes.  
Always wear approved eye goggles or a full face  
shield and protective gloves when handling elec-  
trolyte or filling the battery.  
• Always protect your eyes from falling debris or small  
parts by wearing approved safety glasses or goggles.  
• Remove the ignition key and disconnect the spark  
plug wires before working under a unit. Accidental or  
inadvertent starting could result in serious injuries.  
• Lead-acid batteries also produce hydrogen, a color-  
less, highly explosive gas that can be easily ignited  
by a single spark. Charging the battery incorrectly or  
hooking up jumper cables improperly can cause  
sparking, and must be avoided. Always follow rec-  
ommended battery charging and jumper cable pro-  
cedures.  
Proper Tool Use  
• Use power and hand tools only for the use that they  
were designed. Never alter or modify tools, or impro-  
vise using tools that are not suitable for the job at  
hand.  
• When removing or installing battery cables, discon-  
nect the negative cable FIRST, and reconnect it  
LAST. If not done in this order, the positive terminal  
could be accidentally shorted to the frame by a tool,  
creating a dangerous spark that can ignite nearby fuel  
vapors or escaping hydrogen gas from the battery.  
• Keep all hand and power tools in good repair, and put  
them away when done to avoid cluttering the work  
area. Use extra care when using corded tools around  
moving or rotating parts such as belts and pulleys,  
since the cord could get caught and suddenly pull the  
tool, or you, into the area of moving parts.  
• Keep battery securely fastened in position with vent  
tube directed down and out of battery compartment.  
Replace battery if electrolyte leakage occurs. Make  
sure the battery vent tube is properly installed, and is  
not plugged with clippings or other debris. Replace  
the vent tube if cracked, damaged, or missing from  
unit.  
• Always check the unit to ensure that all hand and  
power tools and tool attachments have been removed  
from the unit after use. Small tools and tool attach-  
ments left on the equipment can fall into the cutting  
path when the unit is placed into service, and become  
a hazard to bystanders if struck by mower blades.  
• Old batteries should be disposed of by recycling.

General Information  
Safety Rules  
Work Area Safety  
General Servicing Safety  
• Always keep the work area clear of clutter from dis-  
carded parts, and debris from parts boxes or packag-  
ing materials. Small parts, hardware items, and other  
debris or refuse left lying around can become slip,  
trip, and fall hazards if not removed and discarded of  
properly.  
• Always check safety devices and switches for proper  
operation - never alter these devices or make tempo-  
rary or makeshift repairs. Use only factory-autho-  
rized parts and procedures, and check newly-  
installed parts for proper operation.  
• Make sure all hardware items are properly tightened,  
especially blade attachment bolts. Replace any hard-  
ware that appears damaged.  
• Always observe general shop safety rules for house-  
keeping, and tend to oil spills and other spilled fluids  
promptly to prevent slip and fall injuries.  
• Check brake operation, and adjust or repair as  
required. Always comply with factory specifications  
on settings and adjustments.  
• Allow sufficient work area around the equipment you  
are working on to permit comfortable working posi-  
tions. Never put yourself in a position that would pre-  
vent you from escaping quickly in the event of emer-  
gencies such as sudden shifts in equipment position,  
fire, or other situations requiring an immediate reac-  
tion on your part.  
• Check grass catcher components for wear, damage,  
or deterioration, and replace with factory authorized  
parts if necessary.  
• Always make repairs using factory authorized  
replacement parts only. Using parts that don’t meet  
factory specifications can result in sudden or prema-  
ture failures, poor or erratic equipment performance,  
and potential safety hazards to operators and  
bystanders.  
Compressed Air Safety  
• Always use care when using compressed air to blow  
dirt and debris off equipment - always direct the air  
blast away from yourself and others in the area, and  
protect your eyes with safety glasses to prevent injury  
from particles that may blow back toward your face.  
• Always comply with factory specifications on settings  
and adjustments when installing new parts, making  
repairs, or performing routine service procedures.  
• Never use high pressure air directly against your skin  
to clean dirt and debris - the air pressure could actu-  
ally force foreign material or fluids into your skin,  
causing serious injuries.  
• Always test repairs before releasing units to cus-  
tomers, paying special attention to any items that are  
safety-related. Correct any problems noted, and re-  
check to ensure that the problems have been fully  
remedied.  
• Use care when filling tires - lawn and garden tractors  
utilize low pressure tires, and over-pressurization is  
hazardous to you and anyone who operates the  
equipment with improper tire pressures. Always con-  
sult the air pressure recommendations for the unit  
involved before adding additional air to the tires.  
• Make sure all safety and operating instruction decals  
are legible, properly located, and securely attached.  
Replace any decals that can’t be read or are in dan-  
ger of falling off.  
Grease & Lubricant Safety  
• Always advise equipment owners of any potential  
operating or safety problems that may be arising due  
to anticipated wear, and request that the owner  
address the problem before a hazard develops.  
• Normal service and maintenance involves the use of  
oils and greases that could present a fire hazard if  
not handled properly. Always dispose of oily rags  
properly to prevent fires caused by spontaneous  
combustion.  
• Never allow a unit to be placed back into service if a  
serious safety or operating problem is evident.  
Advise the owner of the problem and the possible  
hazards associated with the problem, and request  
permission to correct the deficiencies.  
• Spilled lubricants pose dangerous slip hazards and  
must be taken care of immediately. Wipe up spills  
carefully, or use absorbent materials to soak up  
spilled fluids. Always dispose of rags, paper towels,  
and other saturated absorbent properly.  
• Use extreme care when working on older models that  
do not have all of the latest safety devices and  
switches. Disengage the PTO and transmission  
before starting the unit, or commencing repairs.  
• Store oils and greases away from flame or other igni-  
tion sources. Petroleum-based fluids can be ignited  
by smoking materials and sparks - always treat oils  
and greases as potentially flammable materials.  
Always cap oil and grease containers when done  
using, and store or dispose of properly.  
• Always use care when removing or installing parts to  
prevent damage from dropping or rough handling.  
Support heavy parts properly to prevent damage or  
personal injury to yourself and others.

Safety Rules  
General Information  
INSPECTION  
GENERAL REPAIR INFORMATION  
Once cleaned, bearings can be properly inspected for  
wear, scratches, visible damage such as corrosion,  
cracked seals or scorching, and rough, or noisy, opera-  
tion. Bushings can be visually checked for scratches,  
uneven wear, or other visual damage.  
In addition to providing specific repair procedures for the  
equipment listed at the beginning of this section, this  
manual provides the following additional general instruc-  
tions for dealing with repairs to various types of compo-  
nents.  
LUBRICATION  
This information is designed to help you deal more effec-  
tively with these components by providing basic service  
knowledge and other useful tips.  
After passing inspection, bearings and bushings should  
be lubricated in accordance with factory specifications,  
and reinstalled according to the appropriate installation  
instructions. New bearings and bushings must also be  
properly lubricated before use. For optimal performance,  
and as a practical preventive maintenance measure,  
bearings and bushings used in pairs or multiple sets  
should all be replaced at the same time.  
Bearings & Bushings  
Roller bearings, ball bearings, and bushings are used to  
provide support to rotating shafts and other parts such as  
gears, pulleys, and sprockets that are used to transmit  
rotary motion. Over time, bearings and bushings may  
require additional lubrication to transmit this rotary  
motion with minimal friction, or may need replacement  
due to normal operation and wear. Normal service for  
bearings and bushings includes removal, cleaning,  
inspection, lubrication, and replacement.  
Belts & Pulleys  
Belts and pulleys transmit rotary motion from power  
sources to work components, providing the force needed  
to drive transmissions, operate mower decks, and power  
various attachments. This continual use eventually  
causes belts to wear out, and over time may also require  
the replacement of pulleys and pulley bearings.  
REMOVAL  
Belt wear and various types of damage are easily  
checked by visual examination, which is covered in  
greater detail elsewhere in this manual. Pulleys may  
also be checked visually for wear or apparent damage,  
but pulley bearings usually require removal, cleaning,  
and inspection to determine if replacement is required.  
Most bearings and bushings used on the listed equip-  
ment can be easily removed by following the appropriate  
detailed procedures found throughout this manual. Care  
should always be exercised to avoid scratching or dam-  
aging the bearing or bushing, the mounting shaft, and  
surrounding components. Bearing or bushing removal is  
usually necessary when excessive play or wobble is  
noticed on the part it supports, when unusual noise or  
vibration is apparent, or when a burning smell is present  
at the bearing location.  
Belt and pulley life can be optimized by making sure that  
proper belt tension and alignment are observed when  
belts are installed. Proper belt tension and alignment  
should also be maintained by performing periodic checks  
and adjustments. In addition, only factory authorized  
replacement belts will minimize problems caused by  
size, thermal instability, and variations in quality.  
CLEANING  
Sealed bearings and bushings can be cleaned by careful  
wiping with a cloth. Bearings with one-sided or remov-  
able shields and plain bushings can be cleaned by  
immersion in safety solvent, and brushing with a part  
cleaning brush. Oil-impregnated bushings, and bushings  
made of nylon or other synthetic materials, can be  
cleaned with safety solvents, or wiped clean, but should  
not be immersed in solvent for periods longer than that  
necessary to remove heavy or caked-on build-ups of  
grease. All petroleum-based solvents are flammable, so  
appropriate precautions regarding flames, sparks, and  
other ignition sources should always be observed.  
Gasoline should never be used because of its volatility  
and its highly toxic nature.  
Electrical Parts  
The electrical parts used on these units have been  
specifically engineered for outdoor power equipment,  
and are designed to provide years of reliable operation.  
As with all electrical components and systems, electrical  
contacts must be kept clean and dry, and all terminations  
must be securely fastened or connected. Also, all elec-  
trical components, wiring, and connectors should be peri-  
odically inspected for corrosion, signs of excessive heat  
build-up, or other damage that signals that it is time to  
repair or replace the item.  
Specific procedures for electrical troubleshooting and  
most common repairs is covered in separate sections of  
this manual.

General Information  
Safety Rules  
Fasteners & Hardware  
Required Tools & Equipment  
All hardware and fasteners used in this equipment must  
meet factory specifications for SAE grade, size, and  
torque, and must be kept securely tightened. Locking  
hardware that degrades with use should be replaced  
when service is performed in affected areas. Always  
observe factory specifications for torque, or consult the  
torque chart for torque information.  
All repairs in this manual can be accomplished with stan-  
dard mechanic’s hand tools. The use of appropriate  
power tools such as impact wrenches and power drivers  
may aid in part removal and replacement, but care must  
be exercised to avoid causing damage to components  
from excessive tightening. Transmission service, steer-  
ing service, tire and wheel service, and service to com-  
ponents located under the frame also requires the use of  
a jack with suitable capacity, and jack stands to support  
the unit being worked on.  
Genuine Replacement Parts  
Only factory authorized replacement parts should be  
used when making repairs or performing routine mainte-  
nance. The use of parts that do not meet stringent facto-  
ry specifications can cause poor performance, premature  
failures, and lead to potential safety hazards. In addition,  
the use of non-factory authorized replacement parts will  
void your warranty.  
Systems Checks  
In addition to performing individual component service,  
components affected by related parts changes should  
also receive attention at the time service is performed.  
Examples of this include part replacements that are part  
of a safety device, electrical components, transmission  
components, and pulleys that are part of the same power  
delivery system. Giving attention to related parts will  
help ensure that the parts most likely to be affected by  
the wear of similar or nearby parts, or parts subjected to  
the same amount of stress or wear, are given appropri-  
ate attention before a failure can occur.  
Hydraulic Parts  
Hydraulic parts are adversely affected by dirt and conta-  
mination, and care must be exercised when performing  
service on these parts to prevent foreign material from  
entering. Specific service information appears else-  
where in this manual, and all precautions and proce-  
dures must be followed when repairing or servicing these  
parts.  
Paint  
The paint on outdoor power equipment provides for an  
attractive appearance, as well as a barrier to corrosion  
caused by exposure to moisture in the environment.  
Scratches, abrasions, and other damage to painted sur-  
faces should be repaired promptly to prevent the forma-  
tion of rust and premature part failure. Factory supplied  
paints are available that provide both an accurate color  
match and superior corrosion resistance.

16. Attach tie rod (B, Figure 8) to new axle (A) using two  
spacers (C), two 3/8-16 x 1 square head bolts (D),  
and two 3/8-16 flange nuts (E) as shown.  
Do not allow dirt, water, or other debris to  
enter the expansion chamber or  
transmission. Even a small amount of dirt  
can damage the transmission

17. Clean and grease spacer (B, Figure 9) previously  
removed from old axle. Then install spacer (B) into  
new axle (A) as shown.  
The hydraulic system is powered by the hydrostatic  
transmission charge pump, and subsequently shares oil  
with the transmission. It is for this reason that great care  
must be taken when adding or replacing hydraulic  
system parts to prevent contaminants from entering the  
transmission.  
15. Install hydraulic perma-push fittings  
(B, Figure 7) to steering cylinder (A) as shown.
