description
The heart of the picker is the two highly effi-
cient spindle-type picking units. There are two
drums of spindles per picking unit. The front
drum consists of 16 cam-controlledpicker bars,
and the rear drum consists of 12 cam-controlled
picker bars. Each picker bar, has 14 (low drum
unit) or 20 spindles (high drum unit). Thus the
picker has 784 (low drum unit) or 1120 (high
drum unit) individual barbed spindles that pick
cotton from the plants.

• The 99 is a practical two-row cotton picker.
  Operating costs are low. It is easy to handle and
  transports fast.
• The picker consists of four basic components
• Picking units.
• Fan delivery system and basket.
• Operator's platform and controls.
• Propelling mechanism.
• These basic components are mounted in such a way
  that the cotton picker is well balanced and the
  picking operation is efficient.
• Picking Units

DOFFER' PLATE
Doffer
Pi cket bar A doffer assembly is provided,
for each spindle drum, to unwind the cotton
from the spindles and deliver it to a chute in
the door. Each assembly consists of a shaft with
14 or 20 aluminum alloy doffer plates with rubber
doffers molded to each plate.

deac pftori 5 How the piching units work
Knowing what is going on inside the picking unita
will be a great help to you. It will give you a
better understanding of the capabilities and
limitations of a mechanical cotton picker. You
will also know why certain adjustments are nec-
essary and when to make the adjustments.
IfOISTENER PAD
The Illustration below shows what happens during
the picking cycle. At "A, the spindles go under
the moisteners and are cleaned of lint, plant
sap, and stain by a film of water.
Then the cleaned spindles start through the grid
bars at ' 'B.' The speed of the spindle drums is
synchronised wlth the picker ground speed (2.1 or
2. 7 miles per hour) so the spindles have no
forward or backward motion in relation to the
cotton plant. The rotating spindles simply poke
straight Into the cotton plant and pull straight
back. Because of this, the spindles can brush
past unopened bolls and stalks, leaving them
undamaged.
There 1s also a spindle moistener column for each
spindle drum, that wtpes each spindle with water,
to keep it clean, for a better job of picking
cotton.
Stalk lifters guide the cotton plant into the
plcklng zone of the unit where grid bar8 and
pres- sure plates take over to hold the plant in
posi- tion for picking.
At 'C,' the spindles are all the way out and
wrap the cotton fibre onto the spindle barbs.
Then the spindles move back through the grid
bars, pulling the cotton out of the open bolls
and through the grid bars as shown at D."
At ''E the cotton is being removed from the
splndles by the doffer. The spindles move back-
wards under the doffer so that the dofler pads
can unwind the cotton from the spindles.

6 descrlftlon Fan delivery system and basket
The regular basket will hold 1800 pounds of seed
cotton. Wtth basket extension, the basket will
hold 2100 pounds, so that you will have to dump
It fewer tlmes during a day. Two powerful
double-acting hydraulic cylinders raise and
lower the basket for dumping. The lid opens and
closes automatically as the basket 1s ralsed and
lowered.

Picker. He is up high out of the dust and dirt,
with maximum vis Ability of the working area. All
controls are within easy reach. After a couple of
trips up and down a field, the operator will feel
perfectly at home on this cotton picker.
Propelling mechanism The cotton picker iS
powered by a 6-cylinder gasoline or LP-gas
engine. The power 1s trans- mitted through a
drive shaft to the transmission, final drive and
thus propelling the drive wheels.

gauge The fuel gauge Indicates the liquid level
In the fuel tank. It is calibrated to show the
percentage of liquid fuel in the tank. Liquid and
vapor withdrawal valves These valves control the
flow of fuel to the
engine. The VAPOR valve, wiien opened, supplies
vapor from the top of the fuel tank for starting
the engine. The LIQUID valve permits
withdrawal of liquid fuel from the tank for
normal operation. Both valves are equipped
with excess-flow valves which automatically
close whenever the flow exceeds the normal amount
used to operate the cotton picker. These valves
must be opened slowly to prevent closing the
excess-flow valves. If a fuel line is
accidentally broken, the excess- now valves do
not shut off the now completely. If one of the
excess-flow valves closes, it can be reset by
closing the withdrawal valve manually.

operation
Know your cotton picker

• Every hour, drive the picker for 5 to 10 minutes.
  This will recireulate the lubricant in the
  transmission housing and keep all bearings and
  gears lubricated.
• Listen for any unusual noises In the picking
  unit. If any irregular noises occur, stop the
  picker immediately and determine the cause.
• Periodically, check the engine oil pres- sure,
  temperature, and battery charging rate.
• After the eight-hour run-in period has been
  completed, check the entire machine for loose
  bolts, belts, etc.
• Engine run-in period
• Before your new cotton picker was Shipped from
  the factory, the engine crankcase was filled with
  "breaking-in ' oil.
• Check the crankcase periodically to make sure
  that an adequate supply of oil is maintained. If
  it becomes necessary to add oil during the
  picker run-in period and during the first 20
  hours of engine operation, use MM or MS SAE 10W
  or SAE SW-20 engine oil. After 20 hours of opera-
  tion, Including the run-in period, drain the
  break- ing- in oil and fill the crankcase with
  the proper viscosity oil as shown on the chart on
  page 42. Thereafter, drain and refill the
  crankcase every 150 hours of operation.

Before starting to pick cotton, read this man-
ual. The information in it is the result of years
of experience in the design and operation of me-
chanical cotton pickers. We want you to be happy
with your new John Deere 99 Cotton Picker. We
know it will do good work for a long time if op-
erated and adjusted properly. This manual tells
you how to get from the picker the performance
and long life that have been designed and built
into It. Running-in the new cotton picker It has
been recommended that the dealer run- in your new
cotton picker for eight hours prior to the
delivery. If the run-in has not been completed,
we recommend that it be done as follows. Make
sure the entire machine has been lubricated, re-
gardless of the lubrication interval. 1. With the
engine running at about half throt- tle, engage
the picking unit gearshift lever. After about 10
minutes, speed up the engine to full throttle.
SAFETYFIRST Every operator must cooperate fully
In the shielding of rotating powershafts-an
exposed powershaft can be deadly.

3. Make sure the shut-off valve under the fuel
tank is open.

• Careful Inspection of the cotton picker before
  starting work each day will prevent needless de-
  lays and breakdowns tn the field. Make the
  follow- ing checks and adjustment.
• Fill fuel tank. If picker has an LP-Gas en- gine,
  see page 41. If it has a gasoline engine, use a
  good regular grade of gasoline. See page 38.
• Check water level in radiator. Fill with soft
  water if available. Do not use water contain- ing
  alkali. If water has been drained to prevent
  freezing, DO NDT start engine before filling the
  cooling system.

1. Check tire inflation. See chart on page 16 for
   correct tire Inflation.
2. Clean out the area around the doffers and
   moisteners. Waah out the screened area of all
   suction doors and the doffer rod grates. See page
   51.
3. Perform neeeBsary lubrication services. See
   pages 44 through 62.
4. Check water level in the water supply tank. See
   page 33.
5. Inspect belts and chains for proper tension and
   alignment. Be sure there are no loose bolts or
   missing cotter pins.

4. It engine has not been operated Jor a per lod
of time or gasoline tank has been dry, work
priming lever up and dovrn as shown to force
gasoline into carburetor. Leave lever down so
that pump will remain operative.

1. Advance throttle lever approximately 1/4 open.
   Turn ignition switch on and pull choke control
   knob all the way out. Depress clutch pedal, and
   at the same time press starter button. Ae soon as
   the engine starts, push choke knob in. Release
   clutch pedal.
2. Check oil pressure gauge to see if it is
   registering pressure. If no pressure 1s shown,
   stop engine and determine cause.

• Starting the gasoline engine
• Be sure transmission gearshift lever is in
  neutral position.
• Make sure picking unit gearshlft lever and fan
  gearshlft lever are disengaged.

7. Do not place engine under load until heat
indicator gauge shows that temperature of water
in cooling system 1s rising.
See page 14 for Instructions on stopping the
engine.

Starting the LP-Gas engine
1. Open the VAPOR withdrawal valve slowly. If
valve is opened too fast, it may cause the ex-
cess-flow check valve to close and prevent
normal flow of vapor. If this happens, close the
vapor withdrawal valve to reset the check valve
then, open the vapor withdrawal valve slowly.
5. Check oil pressure gauge to see if it is reg-
igtering pressure. If no pressure is shown, stop
engine and determine cause.
6. After the engine is started, operate it on
vapor until the cooling system is warm and water
temperature gauge needle rises.
2. Ptace transmission gearshlft lever in neu-
tral position.
7. Slowly open the LIQUID withdrawal valve, After
liquid withdrawal valve 1s completely open, close
the vapor withdrawal valve.
3. Be certain the picking unit and fan control
levers are disengaged.
8. Check the oil pressure gauge when engine
starts. If oil pressure drops, STOP immediately
and determine cause.
4. Turn ignition switch on and advance throt-
tle lever approximately 1/4 open. Depress clutch
pedal. Pull choke control rod all the way out and

Starting the picker
For low range picking unit speed, use first gear
(2.1 mph). For high range picking unit speed, use
second gear (2.7 mph). Third and four gears are
transport speeds. Stopping the picker To stop the
picker, pull the throttle back to decrease
engine speed. When the engine has slowed down
the picker, depress the clutch pedal and apply
the brakes evenly to bring the picker to a full
stop. Shift transmission, picking unit drive,
and fan drive into neutral and release clutch
pedal.
1. Test the raising and lowering of the picking
units.
2. Test dumping of the baeket. See page 15.

• Check operation of the suction fan and pick- ing
  units.
• Disengage the englne clutch.
• Engage the fan gearshift lever.
• Select the picking unit speed range. If low
  range picking speed (2.1 mph) is desired, move
  the lever forward. If high range picking speed
  (2.7 mph) is de- sired, move the lever
  backward. Be sure to match ground travel speed
  with picking unit speed.
• Set throttle one-third open and slowly
• engage clutch. Listen for unusual sounds
  while slowly bringing the engine up to full
  speed. Run the units at half speed for a few
  minutes to warm them up.

If you are going to get off the picker, shut off
the engine (see page 14) and engage the brake
latches.
Use of brakes The two independent brake pedals
can be used as steering aids when making sharp
turns at row ends.
When stopping the picker at high speed (3rd and
4th speeds), apply the brakes evenly to avoid
drawing the picker to one side.
4. Reduce engine speed to slow Idle, disen-
gage clutch, and let suction fan coast to a stop.
Then shift into desired transmission speed. Re-
lease brakes, and slowly engage clutch. Select
transmission speed to match picking unit speed.
CAUTION Reduce ensue speed before apQfyiag
brakes.

Transporting
Gtopping the gasoline engine
Before stopping the engine, allow it to oper- ate
for a short time at slow idle. Then turn off
ignition swltch. Sudden cooling of a hot englne
causes extreme contraction of heated metal parts.
In freezing weather, never drain water
immediately after stopping. First allow engine to
cool off grad- ually.
If engine ts not to be used for a perlod of
time, shut off gasoline supply at valve located
under fuel tank, Remove drain plug on under- side
of carburetor and drain carburetor. Be sure to
replace this plug arter draining to prevent dirt
from entering carburetor. Draining will prevent
accumulation of gum in carburetor caused by
evaporation of gasoline. This gum 1s a contrib-
uting factor toward hard starting and poor en-
gine operation.
CA UTION.' The cotton picker is a large, hear y
mach' ie be sure to reduce speed uihen traveling
over rough ground,
Raise the picking units to the highest position
before transporting.
When the cotton picker is being moved along a
highway, keep as far to the right as possIble.
When traveling on a public road at night or dur-
ing periods of low visibility be sure the cotton
picker has proper lights, including a warning
lamp at the extreme left-hand side.
Stopping the LP-GaB engine
Before stopping the engine, allow it to idle for
a minute or so then close the withdrawal valves
and let the engine run until fuel in con- verter
1s exhausted and engine dies, Then turn Ignition
switch off. With the fuel lines partially empty,
there is no chance of damage to the various
parts due to changes In temperature and pressure
of the fuel. Also, If liquld fuel is left in the
lines when engine 1s stopped, hard starting may
result.
CAUTION Warning lamps and other lighting
equipment are auailab ie from your John Deeze
dealer. These lights gift cram other ditezs
that are teat eltngon the road, thus helplng to
present pos sible Injury or death.
Be sure withdrawal valves are closed
tightly. This 1s a recommended safety
procedure. Sudden cooling of a hot engine causes
extreme contraction of heated metal parts. In
freezing weather, never drain water immediately
after stopping. Flrst allow engine to cool off
gradually. If the cooling system ie drained,
drain the con- verter by removing the plug under
the converter. Also drain the converter sump
and the fuel strainer.

Towing the picker
Cold weather operation Special preparations must
be made to operate a cotton picker when the
temperatures are below 32 F. If these
preparations are made properly, the picker will
give just in good service as when operating In
warm weather.

• Engine
• Drain and refill crankcase with SAE 10W or
• SAE 5W-20. See pages 42 and 58.
• Use an anti-freeze solution in the radiator. This
  will eliminate filling and draining the radi-
  ator and LP-Gas converter daily.

When towing the cotton picker either forward or
backward behind a truck or some other fast moving
conveyance, the drive shaft for each wheel
should be disconnected. This can be ac-
complished by removing the roll pln from the
coupling sleeve and sliding the sleeve inward on
the shaft. The sleeve should be wired securely to
prevent It from engaging accidentally.
3. Keep the batteries well charged, A par- tially
discharged battery freezes more quickly than a
well charged one.
4. Drain radiator, engine block, and LP-Gas
converter sump daity if the cooling system is not
protected with antl-freeze. Picker water
system Drain the water tank and strainer at
night. Then refill the tank before the next day's
opera- tion.

! oferation Care of rubber tires It is very
Important that tires be kept properly inflated,
as considerable damage may result to the tire
when proper pressure is not maintained. Lack of
pressure will allow the tire to slip on rim or to
buckle the sidewalks, resulting In torn valve
stems, fabric breaks, and uneven tread wear. Too
much pressure causes undue strain on fabric, ex-
cessive tread wear and allows tire to cut In more
on wet ground, and greatly increases the draft.
Avoid stumps, stones, deep ruts, and other haz-
ards. It 1s important that valve cap be screwed
onto valve stem finger tight, after gauging and
inflat- ing tire, to insure proper inflation
pressure and a positive seal against n leaks.
Dumping the basket
Check hub bolts for main wheels occasionally,
making sure these bolts are tightened to 130
foot- pounds torque. Check tire Inflation
periodically. See chart below.
The picker dumps the basket to the left. Pull the
basket lift lever to the rear to raise and dump
the basket.
Never drive the picker with the basket raised.
After the cotton has been dumped, lower the
basket by moving the control lever forward.

• The fundamentals of mechanical cotton picking
• AU 112 and 1-galton cans as AN3097S. If other
  ceiling agents are used, uaIch for spindle cor-
  rosion. If co onion is dete cted, use a diffe
  sent setting agent or operate plcber uithout a
  me S- ting agent.
• The ideal picking condition Is when the cotton
  bolts are well open, clean, and fluffy.
• Defol lation is recommended to get greater
  picking efficiency, cleaner cotton, and less
  leaf and trash, resulting in a better grade of
  cotton.
• The proper harvest date depends almost entirely
  on crop and weather conditions.

Successful mechanical cotton picking re-
quires a thorough understanding of the funda-
mentals of cotton picking and Intelligent use of
the cotton picker to meet the conditions in the
field being picked.
7. The ground should be firm enough to pro- vide
good traction without excessive wheel slip- page.
This 1s Important because the speed of the
picking mechanism is accurately tlmed with the
forward ground speed of the picker. Wheel slip-
page reduces ground travel, destroying the syn-
chronization between picking speed and ground
speed, which can cause the stripping of unopened
green bolls and excessive plant mutilation.
These fundamentals, in brief, are
1. The mature open bolls must be selected and
picked cleanly while the immature bolls and
plants are left undamaged.
8. Proper preparation of cotton fields for
mechanical harvesting will mean less trouble
and more profitable operation, Fields should be
kept clean and free from roots, stones, bricks,
and other foreign material.
2. Cotton boils seldom ripen and open all at one
time, Therefore, a field is normally picked two
or three times before the entire field 1s
harvested.
3. The use of a wetting agent ln the water will
distribute the water more evenly on the
spindle. Also, less water will be required,
8. Do a good Job of cultivating. Weeds and grass
do not affect the mechanical operation of a
spindle-type cotton picker but will cause more
trash and foreign material to be mlxed with the
cotton In the basket, making it more difficult
to gin, usually resulting in a lower grade.
