• Keep emergency numbers for doctors, ambulance
service, hospital, and fire department near your telephone.
Use Care In Handling and Servicing Batteries
MIF

Safety - 2
SAFETY
Prevent Battery Explosions
• Keep sparks, lighted matches, and open flame away
from the top of battery. Battery gas can explode.
• Never check battery charge by placing a metal object
across the posts. Use a volt-meter or hydrometer.
• Do not charge a frozen battery; it may explode. Warm
battery to 16°C (60°F).
Prevent Acid Burns
• Sulfuric acid in battery electrolyte is poisonous. It is
strong enough to burn skin, eat holes in clothing, and
cause blindness if splashed into eyes.
Avoid acid burns by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is added.
4. Avoiding spilling or dripping electrolyte.
5. Use proper jump start procedure.
If you spill acid on yourself:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize the acid.
3. Flush your eyes with water for 10 - 15 minutes.
4. Get medical attention immediately.
If acid is swallowed:
1. Drink large amounts of water or milk.
2. Then drink milk of magnesia, beaten eggs, or vegetable
oil.
3. Get medical attention immediately.
Wear Protective Clothing
MIF
Wear close fitting clothing and safety equipment
appropriate to the job.
Prolonged exposure to loud noise can cause impairment or
loss of hearing. Wear a suitable hearing protective device
such as earmuffs or earplugs to protect against
objectionable or uncomfortable loud noises.
Operating equipment safely requires the full attention of the
operator. Do not wear radio or music headphones while
operating machine.
Use Care Around High-Pressure Fluid Lines
Avoid High-Pressure Fluids
MIF
Escaping fluid under pressure can penetrate the skin
causing serious injury.
Avoid injury from escaping fluid under pressure by stopping
the engine and relieving pressure in the system before
disconnecting or connecting hydraulic or other lines.
Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands
and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene may result. Doctors unfamiliar with
this type of injury should reference a knowledgeable
medical source. Such information is available from Deere &
Company Medical Department in Moline, Illinois, U.S.A.
Avoid Heating Near Pressurized Fluid Lines
MIF
Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severe burns to yourself
and bystanders. Do not heat by welding, soldering, or using
a torch near pressurized fluid lines or other flammable
materials. Pressurized lines can be accidentally cut when
heat goes beyond the immediate flame area.

Safety - 3
SAFETY
Service Machines Safely
MIF
Tie long hair behind your head. Do not wear a necktie,
scarf, loose clothing, or necklace when you work near
machine tools or moving parts. If these items were to get
caught, severe injury could result.
Remove rings and other jewelry to prevent electrical shorts
and entanglement in moving parts.
Use Proper Tools
Use tools appropriate to the work. Makeshift tools and
procedures can create safety hazards. Use power tools
only to loosen threaded parts and fasteners. For loosening
and tightening hardware, use the correct size tools. Do not
use U.S. measurement tools on metric fasteners. Avoid
bodily injury caused by slipping wrenches. Use only service
parts meeting John Deere specifications.
Park Machine Safely
MIF
Before working on the machine:
1. Lower all equipment to the ground.
2. Stop the engine and remove the key.
3. Disconnect the battery ground strap.
4. Hang a “Do Not Operate” tag in operator station.
Support Machine Properly and Use Proper
Lifting Equipment
MIF
If you must work on a lifted machine or attachment,
securely support the machine or attachment.
Do not support the machine on cinder blocks, hollow tiles,
or props that may crumble under continuous load. Do not
work under a machine that is supported solely by a jack.
Follow recommended procedures in this manual.
Lifting heavy components incorrectly can cause severe
injury or machine damage. Follow recommended
procedure for removal and installation of components in the
manual.
Work In Clean Area
Before starting a job:
1. Clean work area and machine.
2. Make sure you have all necessary tools to do your job.
3. Have the right parts on hand.
4. Read all instructions thoroughly; do not attempt
shortcuts.
Using High Pressure Washers
Directing pressurized water at electronic/electrical
components or connectors, bearings, hydraulic seals, fuel
injection pumps or other sensitive parts and components
may cause product malfunctions. Reduce pressure and
spray at a 45 to 90 degree angle.
Illuminate Work Area Safely
Illuminate your work area adequately but safely. Use a
portable safety light for working inside or under the
machine. Make sure the bulb is enclosed by a wire cage.
The hot filament of an accidentally broken bulb can ignite
spilled fuel or oil.

Safety - 4
SAFETY
Work In Ventilated Area
MIF
Engine exhaust fumes can cause sickness or death. If it is
necessary to run an engine in an enclosed area, remove
the exhaust fumes from the area with an exhaust pipe
extension.
If you do not have an exhaust pipe extension, open the
doors and get outside air into the area.
Warning: California Proposition 65 Warning
Gasoline engine exhaust from this product contains
chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
Diesel engine exhaust and some of its constituents are
known to the State of California to cause cancer, birth
defects, and other reproductive harm.
Remove Paint Before Welding or Heating
Avoid potentially toxic fumes and dust. Hazardous fumes
can be generated when paint is heated by welding,
soldering, or using a torch. Do all work outside or in a well
ventilated area. Dispose of paint and solvent properly.
Remove paint before welding or heating: If you sand or
grind paint, avoid breathing the dust. Wear an approved
respirator. If you use solvent or paint stripper, remove
stripper with soap and water before welding. Remove
solvent or paint stripper containers and other flammable
material from area. Allow fumes to disperse at least 15
minutes before welding or heating.
Avoid Harmful Asbestos Dust
Avoid breathing dust that may be generated when
handling components containing asbestos fibers.
Inhaled asbestos fibers may cause lung cancer.
Components in products that may contain asbestos
fibers are brake pads, brake band and lining assemblies,
clutch plates, and some gaskets. The asbestos used in
these components is usually found in a resin or sealed in
some way. Normal handling is not hazardous as long as
airborne dust containing asbestos is not
generated.
Avoid creating dust. Never use compressed air for cleaning.
Avoid brushing or grinding material containing asbestos.
When servicing, wear an approved respirator. A special
vacuum cleaner is recommended to clean asbestos. If not
available, apply a mist of oil or water on the material
containing asbestos. Keep bystanders away from the area.
Service Tires Safely
MIF
Explosive separation of a tire and rim parts can cause
serious injury or death.
Do not attempt to mount a tire unless you have the proper
equipment and experience to perform the job.
Always maintain the correct tire pressure. Do not inflate the
tires above the recommended pressure. Never weld or heat
a wheel and tire assembly. The heat can cause an increase
in air pressure resulting in a tire explosion. Welding can
structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and not
in front of or over the tire assembly. Use a safety cage if
available.
Check wheels for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.

Safety - 5
SAFETY
Avoid Injury From Rotating Blades, Augers
and PTO Shafts
MIF
Keep hands and feet away while machine is running. Shut
off power to service, lubricate or remove mower blades,
augers or PTO shafts.
Service Cooling System Safely
MIF
Explosive release of fluids from pressurized cooling system
can cause serious burns.
Shut off machine. Only remove filler cap when cool enough
to touch with bare hands. Slowly loosen cap to first stop to
relieve pressure before removing completely.
Handle Chemical Products Safely
MIF
Direct exposure to hazardous chemicals can cause serious
injury. Potentially hazardous chemicals used with John
Deere equipment include such items as lubricants,
coolants, paints, and adhesives.
A Material Safety Data Sheet (MSDS) provides specific
details on chemical products: physical and health hazards,
safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a
hazardous chemical. That way you will know exactly what
the risks are and how to do the job safely. Then follow
procedures and recommended equipment.
Dispose Of Waste Properly
Improperly disposing of waste can threaten the
environment and ecology. Potentially harmful waste used
with John Deere equipment include such items as oil, fuel,
coolant, brake fluid, filters, and batteries. Use leakproof
containers when draining fluids. Do not use food or
beverage containers that may mislead someone into
drinking from them. Do not pour waste onto the ground,
down a drain, or into any water source. Inquire on the
proper way to recycle or dispose of waste from your local
environmental or recycling center, or from your John Deere
dealer.
Live With Safety
MIF
Before returning machine to customer, make sure machine
is functioning properly, especially the safety systems. Install
all guards and shields.

Brakes Theory of Operation - 685
BRAKES THEORY OF OPERATION
Theory of Operation
Brake System Operation
Function:
To provide a means of stopping the machine and to prevent
the machine from moving when not in use.
Theory of Operation:
The brake system consists of plates and disks located
inside the axle housing on each side of the transaxle
assembly.
The brakes are activated by a common pedal hooked to
linkage connected to the individual brake assemblies
located in each of the axle shaft housings. The brakes may
be activated individually by depressing either the left turn
brake pedal or the right turn brake pedal.
Inside each axle shaft housing, the brake components
consist of a brake actuator lever/cam, actuator plate, and
pairs of alternating friction disks and separator plates.
The brake actuator plate is mounted on six steel balls,
which ride inside pockets with ramps on the actuator plate.
The brake friction disks are splined to the axle shafts. The
separator plates are keyed to the brake actuator lever/cam
shaft and cannot move.
When the brake pedal is depressed, the brake actuator
lever/cams rotate, forcing the brake actuator plate to rotate.
As the actuator plate rotates, the ramps on the plate will
allow the plate to ride up, forcing the plate against the
friction disks and separator plates, causing drag and
slowing the machine.
When the pedal is released, the return springs return the
brake actuator lever/cams to the rest position, allowing the
actuator plates to release the pressure on the friction disks
and separator plates.
The machine is equipped with a park brake lock. When the
brake pedal is depressed and held, and the park brake lock
lever is pulled up, a pawl engages with the teeth on the
pivot shaft, locking the brake linkage.
