Safety Suggestions

• Careless use of machinery causes many accidents.
  Make your farm a safer place to
• live and work by following these safety suggest-
  tions. Insist that they be followed by those
  work-
• ing with and for you.
• Do not allow anyone to ride on the harvester when
  it is in motion. Observe the beet harvester
  operation only from the tractor platform.
• Safety shields were designed with your safety in
  mind. Keep them in place when operating the
  harvester.
• Always shut off the engine, set the brakes, and
  disengage the PTO when leavin g the tractor. Re-
  move the ignition key when leaving the tractor
  unattended.
• Reduce speed before turning or applying the
  brakes. Apply both tractor brakes evenIy when
  making emergency stops. Drive at speeds slow
  enough to insure your safety.
• Wear relatively tight and belted clothing. Loose
  clothing may catch on some part of the machine
  and cause an injry.
• Escaping fluid under pressure can have suffi-
  cient force to penetrate the skin, causing
  serious personal injury. Before disconnecting
  lines, be sure to relieve all pressure. Before
  applying pres- sure to the system, be sure all
  connections are tight and that lines, pipes and
  hoses are not dam- aged.
• Fluid escaping from a very small hole can be
  almost invisible. Use a piece of cardboard or
  wood, rather than hands, to search for suspected
  leaks.
• If injured by escaping fluid, see a doctor at
  once. Serious infection or reaction can develop
  if proper medica! treatment is not administered
  immediately.

Lower the lifter wheels when the harvester is not
in use. Do not work under the frame when the
wheels are raised. Do not lubricate, adjust, or
clean the harvester when it is in motion. Always
block the wheels and use a safety sup- port if
wheels are removed, when working on, under, or
around the harvester. Always shut off the tractor
engine before lubri- cating, adjusting, or
refueling. Do not smoke or use a light with an
open flame when refueling any eng ine. When
transporting the harvester on a road or highway
at night or during the day, use accessory lights
and devices for adequate warning to oper- ators
of other vehicles. In this regard, check local
governmental regulations. Various safety lights
and devices are available from your Jo hn Deere
Dealer.

Operation
HOW THE BEET HARVESTER WORKS
General Description The 4310 Beet Harvester is a
tank-type har- vester which will harvest three 20
to 40-inch (0.50 to 1.02 m) rows or four 20 to
30-inch (0.50 to 0.76 m) rows of topped
beets. The tank has an 8,000 (3 629 kg) pound
beet stor- age capacity, providing maximum sto
rage time between unloadings in high-yield beet
crops. The basic components of the harvester
include the frame and wheels, lifter wheels,
lifter wheel paddles, potato chain primary
conveyor or optional star wheel cleaning bed,
grab rolls, rotary con- veyor, truck or tank
conveyo r, and tank bottom unloading Gonveyo
r. Main Frame The heavy-gauge steel box frame of
the har- vester is supported at the front by the
tractor draw- bar when coupled. This transfers
part of the oper- ating load to the tracto r rear
wheels for increased flotation and improved
traction. When the har- vester is not hooked to
the tractor, it is supported at the front by the
lifter wheels. Wheels and Tires The rear of the
harvester is supported by four wheels and tires.
The two single tires are 12.5L x 15 6-p ly,
tubeless implement the tandem tires are 12.5L x
16 8-ply tubeless implement. The single wheel
frames are attached with leveling p fates to
compensate for side tilt under various loading
and field conditions. Wheel sparing is adjustable
to accommodate the different row spacings. A
third single wheel can be added for increased
flotation. The tandem wheels walk-over"
obstacles and reduce bouncing when working in
rough ground. Lifter Wheels and Paddles The
29-inch (737 mm) solid-rim lifter wheels pen-
etrate the soil just far enough to gently lift
the beets out of the ground. The gap between each
pair of wheels can be increased in 1/4-in ch (6
mm) increments with spacers (attachment) to
accom- modate a large variety of beet sizes.
The revolving steel paddles at the rear of the
lifter wheels knock off dirt as they flip the
beets onto the cleaning bed. The padd les also
clean mud and dirt from the lifter wheels. Rear
pedestal scrapers for additional wheel cleaning
and fan wheel fillers to prevent loss of small
beets are available as attachments. Potato Chain
Primary Conveyor The potato chain conveyor
consists of three side-by-side 32-inch (810 mm)
potato chains, with an incline from the front to
the back. The separa- tions between the chain
links are large en ough to sift out dirt and row
ks while retaining small beets as the beets are
carried up and back to the grab rolls. Cleaning
Bed (Optional) The star wheel cleaning bed
consists of four shafts with 36 star wheels each
and one shaft with 36 hexagon plates. As these
shafts rotate, marry- ing the beets back to the
grab rolls, dirt and row ks are sifted out. Ru
bber spacers between wheels and plates allow
them to sp read sufficiently to work large clods
and rocks though the bed. Grab Rolls and Delivery
System The four large spiral grab rolls also
remove dirt, mud, or trash as they move the beets
into the ro- tary conveyor. Further cleaning is
provided by the open areas in the wheel and true
k-o r tank-con- veyor as the beets are delivered
to the tan k or tru wk. Delivery is controlled by
the operator with the re- versible hydraulic
drive motor which operates the conveyor drive
chain. Tank The tan k bottom unloading Gonveyo r
is actuated by an electro magnetiG clutch, moving
the beets down across a baffle plate onto the
rear set of grab rolls, to the rotary conveyor,
an d truck- or tank-conveyor. In extremely mu
ddy conditions, the operator can recycle all of
the beets over the grab rolls for maximum
cleaning before loading them into the truck.

Electrical Outlet Receptacle If the electrical
outlet receptacle was removed from the tractor,
reinstall it as described on pages 39 and
40. Drawbar In stat I th e d raw bar sup p o rt
(E). Refer to assembly instructions, page 39,
for details of a typical installation. Remove
drawbar clevis if equ ipped. IMPORTANT To
prevent possible damage to the PTO shaft,
tracto r drawbar shouId be adjusted according to
SAE Standards for PTO driven equip- ment (See
your tractor operator's manual). The SAE Standard
establishes the distance between the PTO shaft
and the hitch pin hole provided in the tracto r
drawbar. Power Take-Off IMPORTANT The beet
harvester is designed to operate from a 1000 rpm
PTO only. To prevent possible damage to the
harvester, do not couple to 540 rpm PTO.
Remove the power take-off guard and install
it on the guard retainer. If tractor is
equipped with 540 rpm PTO, convert to 1000 rpm.
(See your tractor operator's manual.) CAUTION If
the master shield is removed for any reaso n, be
sure it is reinstalled be- fore operating the
PTO. Front Ballast Tractor front end stability
is necessary for safe and eff icient operation.
Therefo re, it is important that the proper
amount of weight be installed on the f ront of
the tracto r as recommended in your tracto r
operator's manual. NOTE Ballast recommendations
provide for ade q ua te t ran spo rt sta bility
at re co mm en de d speeds. Additional front
ballast may be required for satisfactory field
operation due to sudden or extreme forces on the
harvester such as may occur when remo ving the
harvester from the ground and turning at row
ends, or during field transport over very rough
ground. Metering Valve Arms The metering valve
arms (B) may be set to pro- vide varying am ounts
of hydraulic oil flow to the remote cylinders
and the Ioading conveyor hy- draulic motor.
(See your tractor operator's man ual). To provide
app rox imately 100 rpm for the load- ing
conveyor driven shaft under no-load condi-
tio ns, set the metering valve for that outlet at
about the 1 oclock position.

PTO SPEED AND POWER Always run the harvester at
full PTO speed (1000 rpm). Co rrect speed is
important for good clean ing an d beet handlin g
capacity. In muddy conditions (especially), grab
rolls must run fast enou gh to throw off mud
before it can build up an d plu g the machine. Be
sure tractor has plenty of power to maintain
speed (at lea st 94 PTO horsepower, 70 k Wj). A
dirty or poor ly Iu bricated machine can
overload a fully rated tractor HARVESTER MUST
BE CLEAN AND WELL LUBRICATED FOR EFFI- CIENT
HARVESTING. Roller chains, in partic ular,
waste power and wear out prematurely if they
are allowed to run stiff and dry. Use John Deere
PT508 or equivalent Iu bricant on chains as
needed. Pull the harvester at 3 to 7 mph (5 to 11
km/h). Adjust speed to keep the primary conveyo r
chain or starwheel cleaning bed and grab
rolls well- covered with beets to give the
best cleaning actio n.
430 Tracto r with Ca b Illus trated
The controls necessary to operate the beet har-
vester, in addition to the tractor propelling
func- tions, are the power take-off clutch
lever, three remote hydrau lic cylinder control
levers, and the electrical control
switch. Hydraulic Controls The remote hydraulic
contro I levers may be used to control the
various hyd raulically operated func- tions as
desired. It is suggested that the hydraulic hoses
be connected to the tracto r outlets to control
the functions as follows Place lever lock clips
(D) in down (float lock- out) position. A - Inner
lever (left-hand coupler) lifting and depth
control. Move lever forward to lower Iifter
wheels (retract cylinder). Move lever rearward to
raise lifter wheels (extend cylinder). B - MiddIe
lever (lower right-hand coupler) angling
cylinder control (row finder override). Move
lever forward to shift machine to the left
(extend cylinder). Move lever rearward to
shift machine to the rig ht (retract
cylinder). NOTE. If this lever is used to operate
the row kinder, obtain an additional lever lock
clip to hold the lever in the forward position.
This will provide live hydraulic power to the
row tinder for field operation.

LIFTER WHEELS
DEPTH AND ANGLING CONTROL

• A - Lift Cylinder B - Angling Cylinder
• The lift (A) and depth (B) control cylinder is
  con- trolled through the tractor hydraulic system
  using the first remote cylinder operating lever
  to the right of the operator. Set the operating
  height such that the lifter wheels penetrate the
  soil just far enough to lift the beets out
  without breaking the tails. The normal depth
  range is from 2 to 4-1/2 inches (51 to 114 mm).
• Finding Correct Depth
• Begin digging as deeply as necessary to keep from
  b reaking beet tails.
• Raise lifter wheels gradually until some beet
  tails are beginning to break.
• Lower lifter wheels about 1/4-inch (6 mm).
• Set depth control cylinder stop to maintain this
  depth.
• Angling Cylinder
• When hydraulic override is used with the row
  finder attach ment, the second remote
  cylinder operating lever to the right of the
  operator controls the angling cylinder. Use the
  angling cylinder to steer the beet harvester back
  onto the rows after turning, and return it to
  the rows as necessary during field operation.
• NOTE Set the stops on the angling cylinder to
  allow full retraction of the piston rod.
• If the row finder is not used, the angling
  cylinder is used to manually return the lifter
  wheels to the rows during field operations and at
  row ends.

A - Shear Bolt B - Safety Bolt
C - Spacer
The lifter wheels are attached to the hubs with
four 1/2-inch shear bolts (A) and one smaller,
loose safety bolt (B). Keep nuts tight on shear
bolts but do not tighten the nut on the safety
bolt. If rocks force the lifter wheels apart, the
four shear bolts will break to prevent damage to
the wheel. The safety bolt will hold the wheel to
the h ub to p revent d am ag e to othe r pa rts
of th e machine. IMPORTANT Replace sheared
bolts with soft or low-carbon bolts (SAE Grade
2) do not use heat-treated or high-carbon bolts.
Use 19H1984 Shear Bolt when wheel fan filler
attachment is not used. Use 19H2163 Shear Bolt
when wheel fan filler attachment is used. Spacers
(Attachment) Use 1/4-inch (6 mm) spacers (C)
between wheel and hu b to increase distance
between lifter wheels for larger beets. Install
by removing the four long bolts in the lifter
wheel. Do not remove the safety bolt (B) as the
spacers can be positioned on either side of it.
13
10 Operation
FAN FILLERS (ATTACHMENT)
Wheel scrapers keep dirt and trash from building
up on the lifter wheels. Install scrapers with
long bolts furnished. Adjust each scraper so the
knife edge just clears the hub and wheel spokes.
Rotate each wheel to insure adequate clearance
when adjusting scrapers.
Check scrapers frequently and clean off accu-
mulated mud and trash. LIFTER WHEEL PADDLES
A - Filler B - 1/2 x 4-inch Bolts Fan-type lifter
wheel fillers (A) are available to close lifter
wheel openings to help prevent loss of small
beets. Install fillers with long bolts (B)
furnished, usin g spacers between fillers and
lifter wheels. IMPORTANT Tighten attaching bolts
to 55 ft-lbs (75 Nm) torque. Check frequently and
retighten as necessary.
A - Pivot Bolt Nut C - Adjusting Bolt B - Lock
Nuts The paddle shaft height is adjustable to
allow positioning paddles according to beet size.
Use higher setting for large beets, lower setting
for small beets. To adjust, loosen nut (A) on
pivot bolt and lock nuts (B) on adjusting bolt
(C). Turn lock nuts clock- wise to raise paddIe
shaft or counterclockwise to lower shaft. Tighten
nuts and pivot bolts. Adjust opposite end in a
similar manner. Paddle spacing must be adapted to
lifter wheel spacing also. (See page 11.) Check
paddle drive chain and adjust if neces- sary.
(See page 29.) NOTE Add extra links to paddle
drive chains for certain height settings. Paddle
Speed The paddle shaft speed can be adjusted to
go either FAST or SLOW, depending on the beet
size, harvester speed, and the amount of dirt on
the beets. The double sprocket on the drive side
of the shaft is reversible. The shaft will
revolve fast when the smaller sprocket is used
(See page 29) it will go slow when the larger
sprocket is used. Install extra chain links
furnished with the har- vester when using the
larger sprocket.

CLEANING BED Star Wheels and
Potato Chain Prlma ry Conveyor
Hexagon Plates (Optional)
A - Rubber 8pacera B - Sta r Whe ele
C - Hexagon Plates D - Steel 8pecer
The potato chain primary conveyor consists of
three 32-inch (813 mm) wide potato ch ains. in-
clined from front to back. The large open area of
the conveyor chain sifts out loose dirt and rocks
as the beets are carried back to the grab rolls
particularly in fields where the soil is dry
and loose. CAUTION Stop the tractor engine, set
the brakes and disengage the PTO before
at- tempting any cleaning. Never climb on the
harvester when the tractor engine is running. The
cleaning bed area is readily visi bI0 from the
tractor seat. Watch carefully for rocks an d
trash which are too large to fall th rough the
chai n. Stop the harvester and clean out debris
often.
The optional star wheel cleaning bed offers in-
creased clean in g capacity, particularly in
rocky or cloddy soil conditions. The uneven
surface pre- sented by the tips of the star
wheels (B) turnbles the beets and shakes loose
clinging dirt. Rubber spacers (A) between star
wheels and hex- agon plates (C) "work" large
clods and rocks throu gh the bed, while retain
ing small beets due to their smoother, mo re
regular surface. CAUTION Stop the tractor
engine, set the brakes, and disengage the PTO
before at- tempting any cleaning. Never climb on
the harvester when the tractor engine is
running. The cleaning bed area is readily visi
ble trom the tractor seat. Watch caref ully fo
r rocks and trash which are too large to wo rk
th rou gh the bed . Stop the harvester and clean
out debris often.

16 Operation
Changing Grab Roll Spacing The first grab roll is
not adjustable. The separa- tion between it and
the second roll is ac hieved with the second
roll. The third and fourth rolls are ind ivid
ually adjustable.
GRAB ROLLS
A - Grab Rolls B - Baffle The grab rolls (A)
perform the principal cleaning action on the
beets, particularly in wet, mud dy fief ds. The
space between the rolls allows dirt, mud, and
trash to fall throu gh. The spiral rolls scru b
the beets as they are moved to the rotary
conveyor. This action provides ef- ficient
cleaning with minimum damage to the beets. Spring
tension maintains roll spacing to retain
small beets, allowing irregular objects such
as clods or rocks to walk'' throu gh the rolls
and be expelled. T he g ra b ro II spac in g is
fa cto ry ad ju sted to 1-3/4-i nches (45 mm)
between each pair of rolls and 2-1/2-inches (57
mm) between the center rolls. This setting is
satisfactory for most field co nditions. Wider
spacin g provides more ag gressive clean- ing.
Narrow spacin g may be necessary for smaller
beets or less ag gressive cleaning. NOTE. To
prevent wedging of material be- tween
rolls, space rolls about 1/8-inch (3 mm)
closer together at left-hand side of
harvester. NOTE. Remove the baffle (B) if mud and
beets build up on it.

D - Adjusting Nut E - Adjusting Nut F - Adjusting
Bolt G - Dampener Spring
4-1/8 inch (I 05 mm) for beet harvesters with
serial numbers below 270. Right-/4and Side
Adjust the second and third grab rolls with their
respective adjusting bolts (A). Turn the boIt
cloc k- wise, after loosening the lock nuts (B),
to increase the distance between the first and
second and be- tween the third and fourth roll.
The distance be- tween the middle rolls is then
decreased. A larger gap between the first and
second and between the third and fourth g rab
rolls provides the most aggressive
action. Tightening the sprin gs down solid is not
recom- mended as grab rolls cannot flex when a.
rock is enco untered.

OperatiON 17
To increase the distance between the middle
two rolls, and decrease the distance between the
first and second and between the third and fourth
rolls, turn the adjusting bolts (A)
counterclock- wise.
Adjusting Filler
B - Adjusting Bolts
A - Filler
Adjust the filler (A) so it does not make contact
with the rear grab roll, yet is not so far away
as to allow beets to be lost. Loosen the
adjusting bolts (B), position the filler, and tig
hten the bolts.
C - Bracket Nuts D - Adjusting Nut The rear or
fourth grab roll position can be changed by
first loosening the bracket nuts (C). Then turn
the adjusting nut (D) clockwise to move the roll
rearward or counterclockwise to move it forward.
Tighten bracket nuts after adjusting.
Adjusting Grab Roll Drive Chain Adjust the grab
roll drive chain after all grab roll spacing
changes. In some cases, it may be necessary to
loosen the chain before adjusting spacing. To
increase chain tension, turn the adjusting nut
(E) clockwise holding the adjustment
bolt (F) on the outside of the housing. If slight
amount of adjustment here does not sufficiently
tighten the chain, remove one of the chain links
and re- adjust. The dampener spring (G)
protects the drive chain from momentary shock
loading due to rocks or other de bris passing
through the grab rolls. IMPORTANT Do not
completely compress spring. Maintain only lig ht
contact between spring and washers at each end of
spring.
