neutral.
AG,OUO6035,84 –19–18MAY00–1/1
Operate Tractor Safely
M47224A –19–02JUN97
TS276 –UN–23AUG88
Features designed into your tractor make operation safer
and let it perform a wide variety of jobs. Use your tractor
only for specified jobs it was designed to perform:
implement carrier, load mover, remote power source, or
transport unit—not a recreational vehicle.
Careless use or misuse can result in unnecessary
accidents. Be alert to hazards of tractor operation.
Understand causes of accidents and take every
precaution to avoid them. Most common accidents are
caused from:
•Tractor upsets
•Improper starting procedures
•Crushing and pinching during hitching
•Collisions with other motor vehicles
•Getting entangled in PTO shafts
•Falls from tractors
Avoid accidents by taking the following precautions:
•Put transmission in neutral (N) and set brakes before
dismounting. Leaving transmission in gear with engine
stopped will NOT prevent the tractor from moving.
•Be sure everyone is clear of tractor and attached
equipment before starting engine.
•Never try to get on or off a moving tractor.
•When tractor is left unattended, place in neutral (N), set
brakes, lower implements to the ground, stop the
engine, and remove the key.

AG,OUO6035,65 –19–17MAY00–1/1
Use Caution on Hillsides
Avoid holes, ditches, and obstructions which cause the
tractor to tip, especially on hillsides. Avoid sharp, uphill
turns.
Never drive near the edge of a gully or steep
embankment -- it might cave in.
Driving forward out of a ditch or mired condition or up a
steep slope could cause tractor to tip over rearward. Back
out of these situations if possible.
Danger of overturn increases greatly with narrow tread
setting, at high speed.
Hitch towed loads only to drawbar. When using a chain,
take up the slack slowly.
AG,OUO6035,83 –19–17MAY00–1/1
Shift to Low Gear on Hills
LV4042 –UN–09JUL99
Shift to a low gear before descending a steep hill to
improve your control of the tractor with little or no braking.
Use engine braking to reduce speed before applying
tractor brakes. Run-away tractors often tip over. Never
coast downhill.
When driving on icy, wet or graveled surfaces, reduce
speed and be sure tractor is properly ballasted to avoid
skidding and loss of steering control.
Additional ballast may be needed for transporting heavy
hitch mounted implements. When implement is raised,
drive slowly over rough ground, regardless of how much
ballast is used.

Avoid Tipping
Do not drive where machine could slip or tip.
Stay alert for holes, rocks, and roots in the terrain, and
other hidden hazards. Keep away from drop-offs.
Slow down before you make a sharp turn.
Use care when pulling loads or using heavy
equipment:
•Use only approved drawbar hitch points.
•Limit loads to those you can safely control.
•Use counterweights or wheel weights when
suggested in this operator’s manual.
Reduce speed and exercise extreme caution on slopes
and in sharp turns to prevent tipping or loss of control.
Be especially cautious when changing direction on
slopes.
Do not stop or start suddenly when going uphill or
downhill.
If machine stops going up hill:
•STOP the PTO.
•Back down slowly.
DX,MIRED –19–07JUL99–1/1
Freeing a Mired Machine
TS1645 –UN–15SEP95TS263 –UN–23AUG88
Attempting to free a mired machine can involve safety
hazards such as the mired tractor tipping rearward, the
towing tractor overturning, and the tow chain or tow bar (a
cable is not recommended) failing and recoiling from its
stretched condition.
Back your tractor out if it gets mired down in mud. Unhitch
any towed implements. Dig mud from behind the rear
wheels. Place boards behind the wheels to provide a solid
base and try to back out slowly. If necessary, dig mud
from the front of all wheels and drive slowly ahead.
If necessary to tow with another unit, use a tow bar or a
long chain (a cable is not recommended). Inspect the
chain for flaws. Make sure all parts of towing devices are
of adequate size and strong enough to handle the load.
Always hitch to the drawbar of the towing unit. Do not
hitch to the front pushbar attachment point. Before
moving, clear the area of people. Apply power smoothly to
take up the slack: a sudden pull could snap any towing
device causing it to whip or recoil dangerously.

Before you leave the operator’s seat, wait for engine and
attachment parts to stop moving.
DX,RIDER –19–03MAR93–1/1
Keep Riders Off Machine
TS290 –UN–23AUG88
Only allow the operator on the machine. Keep riders off.
Riders on machine are subject to injury such as being
struck by foreign objects and being thrown off of the
machine. Riders also obstruct the operator’s view resulting
in the machine being operated in an unsafe manner.
DX,FIRE1 –19–03MAR93–1/1
Handle Fuel Safely—Avoid Fires
TS202 –UN–23AUG88
Handle fuel with care: it is highly flammable. Do not refuel
the machine while smoking or when near open flame or
sparks.
Always stop engine before refueling machine. Fill fuel tank
outdoors.
Prevent fires by keeping machine clean of accumulated
trash, grease, and debris. Always clean up spilled fuel.

Safety
DX,TOW –19–02OCT95–1/1
Tow Loads Safely
TS216 –UN–23AUG88
Stopping distance increases with speed and weight of
towed loads, and on slopes. Towed loads with or without
brakes that are too heavy for the tractor or are towed too
fast can cause loss of control. Consider the total weight of
the equipment and its load.
Observe these recommended maximum road speeds, or
local speed limits which may be lower:
•If towed equipment does not have brakes, do not travel
more than 32 km/h (20 mph) and do not tow loads more
than 1.5 times the tractor weight.
•If towed equipment has brakes, do not travel more than
40 km/h (25 mph) and do not tow loads more than 4.5
times the tractor weight.
Ensure the load does not exceed the recommended
weight ratio. Add ballast to recommended maximum for
tractor, lighten the load, or get a heavier towing unit. The
tractor must be heavy and powerful enough with adequate
braking power for the towed load. Use additional caution
when towing loads under adverse surface conditions,
when turning, and on inclines.

Support Machine Properly
TS229 –UN–23AUG88
Always lower the attachment or implement to the ground
before you work on the machine. If the work requires that
the machine or attachment be lifted, provide secure
support for them. If left in a raised position, hydraulically
supported devices can settle or leak down.
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.
When implements or attachments are used with a
machine, always follow safety precautions listed in the
implement or attachment operator’s manual.

Avoid High-Pressure Fluids
X9811 –UN–23AUG88
Escaping fluid under pressure can penetrate the skin
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting 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.

DX,POISON –19–21APR93–1/1
Prevent Acid Burns
TS203 –UN–23AUG88
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 the hazard 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 15—30 minutes. Get
medical attention immediately.
If acid is swallowed:
1. Do not induce vomiting.
2. Drink large amounts of water or milk, but do not
exceed2L(2quarts).
3. Get medical attention immediately.

DX,RIM –19–24AUG90–1/1
Service Tires Safely
TS211 –UN–23AUG88
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.

Dispose of Waste Properly
TS1133 –UN–26NOV90
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

The rockshaft may be equipped with variable draft control
system.
Use draft load sensing when:
•Operating with a fully mounted implement in hill and
swale terrain. The implement will raise and lower to
follow the ground contours while maintaining a nearly
constant depth.
•Operating in varying soil conditions. The implement is
raised slightly to get through tough spots so you do not
have to shift to a lower gear.
Draft control lever (B) controls amount of load required
before hitch responds. With lever placed fully forward to
the position marked “off” (C), there is no draft sensing.
Placing the lever toward the rear position reduces the
amount of draft load required to override the position
setting set by the position control lever (A) and raise the
rockshaft.
Draft sensitivity ranges can be changed by repositioning
the center link. (See Positioning Center Link in this section
for additional information.)
For draft load sensing operation:
•Initially place position control lever (A) in its fully
rearward position and the draft control lever (B) in the
fully forward (least draft) position.
•With tractor moving, push position control lever (A)
forward to set implement operating depth. Set position
control lever stop (D) so control lever can be brought
back to the same position. The operating depth set-up
will prevent the rockshaft from lowering all the way
when the tractor begins to slip. Then pull draft sensing
lever (B) rearward until desired draft sensing sensitivity
is obtained.
•The position control lever (A) can also be raised slightly
to override the draft control setting to help get through
slippery spots without getting stuck.
•The position control lever (A) can be moved fully
rearward to raise the hitch at the end of the field.

The draft sensing rockshaft center link attaching bracket

Standard position is (C).
Move the center link attachment to holes (B) if:
•Excessive hitch activity or hunting occurs in draft control
operation.
•The rear of the implement raises too much when lifted.
The implement weight which can be lifted is reduced
slightly with the center link attachment in the lower
holes.
•The draft control lever range is too small.
Move the center link attachment to holes (C) if:
•The hitch seems unresponsive in draft control operation
and allows the engine speed to drop too far before
raising the rockshaft.
•The rear of the implement droops and drags the ground
as the implement is lifted.
Upper hole (A) eliminates nearly all draft sensing.

Planning for Maximum Productivity
Proper ballasting is an important factor in tractor
performance. maximum productivity can be achieved
only if tractor weight is appropriate for the job.
John Deere FMO (Fundamentals of Machine
Operations) Tractors, discusses methods of
determining correct tractor weight and ballast selection.
FMO-Machinery Management includes information on
tractor and implement matching and increasing
productivity. .
Your John Deere dealer can assist you with
information on these subjects.
PY80265,05GO867 –19–10SEP05–1/1
Selecting Ballast Carefully
Match amount of ballast needed for each job. What is
right for one job may be wrong for another job. Ballast
for traction and stability.
Factors determining amount of ballast:
•Soil surface-loose or firm.
•Type of implement-integral/semi-integral or towed.
•Travel speed-slow or fast.
•Tractor power output-partial or full load.
•tyres-single, oversize, or dual.
PY80265,05GO868 –19–10SEP05–1/1
Matching Ballast to Load Work
Use no more ballast than necessary, and remove
ballast when it is no longer needed.
Rather than weighing tractor down to pull heavy loads,
try to reduce load. Pulling a lighter load at a higher
speed is more economical and more efficient.
The best way to check for correct ballast is to measure
amount of travel reduction (% slip) of the drive wheels.
Under normal field conditions, travel reduction should
be 10—15 percent.
Add more weight to drive wheels if slip is excessive. If
there is less than 10 percent slip, weight should be
removed.
Too Little Ballast Too Much Ballast
1. Excessive wheel slip 1. Increased load
2. Power loss due to 2. Power loss due to
churning soil carrying extra weight
3. tyre wear 3. tyre strain

Measuring Wheel Slip—Manually
M47166 –UN–31JAN92
1. Place a mark (A) on a rear tyre which is easily
observed (a chalk mark is recommended).
2. With tractor working and implement lowered, mark a
starting point (B) on the ground at the place where the
tyre mark (A) meets the ground.
3. Mark the ground again where the tyre mark (A)
completes 10 full revolutions (C).
4. With implement raised return in the opposite direction.
At the second mark on the ground (C) remark the tyre
(D).
5. While driving the tractor along the same path
(implement raised), count the tyre revolutions required
to reach the starting point (B).
6. Use the return tyre revolutions count and “Wheel
Slippage Chart” to determine slippage. 10—15 percent
is ideal.
7. Adjust ballast or load to give correct slippage.
NOTE: Available horsepower is greatly reduced when
wheel slip drops below 10 percent.

little air space to absorb shocks.
Damage to tyre could occur.
A solution of water and calcium chloride provides safe,
economical ballast. Used properly, it will not damage
tyres, tubes, or rims.
Use calcium chloride to prevent water from freezing. A
mixture of 0.6 kg per liter (5.0 lb of calcium chloride

Service Tyres Safely
TS211 –UN–23AUG88
Explosive separation of at tyre and rim parts can cause
serious injury or death.
Do not attempt to mount a tyre unless you have the
proper equipment and experience to perform the job.
Always maintain the correct tyre pressure. Do not inflate
the tyres above the recommended pressure. Never weld
or heat a wheel and tyre assembly. The heat can cause
an increase in air pressure resulting in a tyre explosion.
Welding can structurally weaken or deform the wheel.
When inflating tyres, 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 tyre assembly. Use a safety
cage if available.
Check wheels for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.

PY80265,05GO881 –19–09JAN07–1/1
Check Tyre Inflation Pressure
Check tyres daily for damage or noticeably low
pressure.
At least every 100 hours of operation, check inflation
pressure with a gauge. Use an accurate gauge having
10 kPa (0.1 bar) (1 psi) graduations.
If tyres contain liquid ballast, use a special air-water
gauge and measure with valve stem at bottom.
NOTE: When furrow plowing or during hillside
operation, tyre pressure can be increased 28
kPa (0.28 bar) (4 psi) ABOVE maximum to
prevent tyre wrinkling or buckling.
IMPORTANT: Always check inflation pressure with
an accurate tyre gauge to prevent
over-inflation. Over-inflation reduces
performance and increases strain of
both tyre and rim.
NOTE: Following inflation information applies to both
front and rear tyres and Tyre Inflation Pressure
Chart.
1. All inflation pressures are calculated for 29 km/h
(18 mph) travel speeds for both diagonal (bias) ply
and radial ply tyres.
2. Operation of tyres at the inflation pressures listed
on chart will result in optimum tractive performance
of the tyre/vehicle system. Correctly inflated radial
tyres will show a large deflection of the sidewall or
“cheeks”. This is normal and will not hurt the tyre if
the inflation pressure is maintained.
3. Inflation pressures less than 80 kPa (12 psi) should
be monitored regularly because of the increased
risk of low pressure air leaks (especially due to
leaking valve cores).
4. Tractors operating on steep side slopes should
increase inflation pressures 28 kPa (4 psi) above
the values listed to compensate for lateral weight
transfer.
5. Tyres run as singles in high traction conditions
sometimes experience bead slip if the bead was not
fully seated or if too much lubricant was used to
mount the tyre. Increasing the inflation pressure will
compensate for this condition but will not cause
reduced traction. Consult your tyre dealer if this
problem occurs.
6. If higher load capacities are needed, contact your
John Deere dealer for tyre manufacturers load and
inflation table information.

CAUTION: Stopping distance increases with
speed and weight of towed loads, and on
slopes. Towed loads with or without brakes that
are too heavy for the tractor or are towed too
fast can cause loss of control. Consider the
total weight of the equipment and its load.
Observe these recommended maximum road
speeds, or local speed limits which may be
lower:
If towed equipment does not have brakes, do
not travel more than 32 km/h (20 mph) and do
not tow loads more than 1.5 times the tractor
weight.
If towed equipment has brakes, do not travel
more than 40 km/h (25 mph) and do not tow
loads more than 4.5 times the tractor weight.
Ensure the load does not exceed the
recommended weight ratio. Add ballast to
recommended maximum for tractor, lighten the
load, or get a heavier towing unit. The tractor
must be heavy and powerful enough with
adequate braking power for the towed load. Use
additional caution when towing loads under
adverse surface conditions, when turning, and
on inclines.
8. Use caution when operating tractor at transport
speeds. Reduce speed if towed load weighs more than
tractor and is not equipped with brakes. (See Towed
Equipment operator’s manual for recommended
transport speeds.)
9. Use additional caution when transporting towed loads
under adverse surface conditions, when turning and on
inclines.
10. Heavy towed or rear mounted implements may start
swaying in transport. Excessive swaying will result in
loss of steering control. Drive slowly and avoid quick
turns of steering wheel. Refer to your implement

liner pitting, and winter freeze protection to -37°C
(-34°F). If protection at lower temperatures is required,
consult your John Deere dealer for recommendations.
John Deere COOL-GARDPrediluted Coolant is
preferred for service.
John Deere COOL-GARD Prediluted Coolant is
available in a concentration of either 50% ethylene
glycol or 55% propylene glycol.
Additional recommended coolants
The following engine coolant is also recommended:
•John Deere COOL-GARD Coolant Concentrate in a
40% to 60% mixture of concentrate with quality
water.
John Deere COOL-GARD coolants do not require use
of supplemental coolant additives, except for periodic
replenishment of additives during the drain interval.
Other fully formulated coolants
Other fully formulated low silicate ethylene or
propylene glycol base coolants for heavy-duty engines
may be used if they meet one of the following
specifications:
•ASTM D6210 prediluted (50%) coolant
•ASTM D6210 coolant concentrate in a 40% to 60%
mixture of concentrate with quality water
Coolants meeting ASTM D6210 do not require use of
supplemental coolant additives, except for periodic
replenishment of additives during the drain interval.
Coolants requiring supplemental coolant additives
Other low silicate ethylene glycol base coolants for
heavy-duty engines may also be used if they meet one
of the following specifications:
•ASTM D4985 ethylene glycol base prediluted (50%)
coolant
•ASTM D4985 ethylene glycol base coolant
concentrate in a 40% to 60% mixture of concentrate
with quality water
Coolants meeting ASTM D4985 require an initial
charge of supplemental coolant additives, formulated
for protection of heavy duty diesel engines against
corrosion and cylinder liner erosion and pitting. They
also require periodic replenishment of additives during
the drain interval.
Other coolants
It is possible that neither John Deere COOL-GARD nor
coolants meeting one of the coolant standards listed
above is available in the geographical area where
service is performed. If these coolants are unavailable,
use a coolant concentrate or prediluted coolant with a
quality additive package that provides cylinder liner
cavitation protection and protects the cooling system
metals (cast iron, aluminum alloys, and copper alloys
such as brass) from corrosion.
The additive package must be part of one of the
following coolant mixtures:

C—Dust Unloader Valve
Air enters the intake system through the open end of the
air cleaner canister. A major portion of the dust is
separated out by air turbulence action of the primary air
cleaner element (A) and passed out into the radiator inlet
air flow through the dust unloader valve (C). If the primary
element becomes plugged, dust is filtered out by the

cells is more than 0.050 or if battery will not charge
above 1.225.
2. Always correct specific gravity reading for electrolyte
temperature variation. Add 0.004 to the reading
obtained in step one for every 10°F above 80°F (add
0.007 to the reading for every 10°above 27°C).
Subtract at same rate if electrolyte temperature is
below 80°F (27°C). Corrected specific gravity of a fully
charged battery is from 1.265 to 1.280.
