HOW THE CUBER WORKS
Por a better understanding of the operation of
your cuber and the Importance of the various ad-
justments In ttils manual, knowledge of the
cubtng cycte 1s important. After alfalfa has
fteld cured to about 10 per- cent moisture, it is
ready for cublng. Upon ptck- up by the cuber the
hay ts sprayed with water (1). A belt-type pickup
(2) picks up the windmw- preferably made with a
wtndrower-as it does a clean job and saves a
maximum number of teaves. The water and a natural
soluble adhesive found on the surface of the
alfalfa plant make the "glue" which helps bond
the cube. The high pressure of the cuber
completes the bonding. An auger behind the ptckup
(3) takes the crop from the pickup and
center-feeds it to the ftrst of two Identical
sets of feed mlls. Drum-type rolls (4) are on the
top of each set smooth rolls (5) are on the
bottom. The smooth roll design and solid deck
reduce lead loss. A reel-type, two-knife
cutterhead (8) chops the hay. In addttlon, the
cutterhead serves as a
mtxtng unlt and delivers the chopped material to
the auger feeder. A large-diameter auger (7), and
flve spiral bars (8) on the inside of the auger
housing, move matertal uniformly to all of the
openings in the dle ring (I). As the material
leaves the auger flight, a single, heavy,
large-diameter press wheet (10) forces the
material into and through the 66 die openings tn
the dle ring. An adjustable deflector (11) around
the outside of the die ring breaks oft cubes in
lengths from 2 to 3 Inches. The dte ring 1s open
at the top so the operator can reach down and
checlr cube sam- ples aa they leave the
ring. Sheet-metal chutes (12) channel the cubes
to a conveyor (13) located beneath the die ring.
The conveyor then carries the cubes to the
elevator (14) at the rear of the machine, which
delivers them into the trailing wagon.

A MMETER
The ammeter indicates the rate of charge or
discharge of the batteries. If ammeter shows
discharge for an extended period during normal
operation, check for a ground, short circuit or
faulty regulator. If ammeter shows high charge
continually, inspect for low batteries ,
faulty connections, low battery water, or bad
regulator. OIL PRESSURE GAUGE This gauge
indicates the pressure of the en- gine
lubricating oilnot the amount of oil in the
crankcase. Oil pressure will vary slightly with
wear, but with recommended oil, it should read
NORMAL at full governed speed (indicated by green
band on dial). If oil pressure drops (indi- cated
by red band on dial), stop immediately and
determine cause.
The throttle lever controls engine speed. Push
lever forward to increase speed pull it rearward
to decrease speed. Lever should be completely
forward against the stop whenever operating in
the fietd. Lever must be completely rearward to
stop the engine using the engine stop

OPERATION PREPARING HAY FOR CUBING
The operator of the John Deere 400 Hay Cuber must
understand the fundamentals of making hay cubes
in order to obtatn satisfactory results. (See
page 3. ) Pressure and adhesion are the two
necessary factors in the production of dense and
durable cubes.
For crop yields of 1 to l- 1/2 tons per acre, cut
a 14-foot swath. For heavier yields, cut a
proportionately narrower swath.
IMPORTANT A hoy condltloner abould be used.
The crisper-typa hay conditioner Is pre- ferred.
Adjust the shields to form the widest possible
wlndrow. Altow the hay to field cure in the
windrows until thoroughly dry. The moisture
content of the hay in the windrow should not
ezceed 12 per cent. For the best quality cubes,
the moisture con- tent In the wtndrow should be
10 per cent or less. Higher moisture hay can be
cubed, btit the increase in moisture will tower
the cube quality and durability. NOTff Be cause
trater is sprayed an the mind- row Just prtoz to
cubing, the itiotst re cmtent of satisfactory
cuber uill tora1fy be from 12 to 1â per
cent. Despite the fact that moisture must be
added to the windrowed hay as it enters the
machine, satisfactory cubtng cannot be
accomplished if there is excessive moisture in
the plant stems. Avoid raking the hay to reduce
the cost of harvesting and save a greater
percentage of the leaves. Aiso, the wide windrows
formed by the windrower provide a large surface
area on which the water is sprayed for a more
uniform distribu- tion of water.
The cube is formed under htgh pressure tn the die
ring of the 400 Hay Cuber. The high pressure
together wtth the natural soluble adhesive found
on the surface of the alfalfa plant causes the
bonding action to take place. The adhesives are
made available for bonding when the alfalia plant
surfaces are moistened (by spraying with water)
just prior to entering the machine. TYPE OF CROP
Cubing will be successful only in legume crops
such as atfalfa because of the natural soluble
adhesives found on the surface of the alfalfa
plant. Hay crops whteh are predominately grass do
not have enough of these natural adhesives and
witl not form a satisfactory cube. However, ac-
ceptable cubes may be formed if the crop does not
contain over 10 per cent grass, provided the
grass is evenly distriixited throughout the
field. High quality cubes are formed from a clean
stand of aifalfa cut in the bud (or pre-bloom)
stage. At this time the protein percentage is
highest, there is a greater percentage of leaves
to stems, and the steme are less coarse than if
allowed to mature.
HARvmsvmoPROCEDqRE The pickup on the 400 Hay
Cuber is designed for picking up the type of
windrow left ray a windrower with conditioner.
Therefore, cut, windrow, and condition the hay
in one operation. Use a windrower with
conditioner, such as the John Deere 215A
Wlndrower with a 228 Crimper.
If the above harvesting procedure is followed,
the crop will cure to the desired moisture con-
tent within a normal time cycle. And, what is
more important, the crop will be cured more
uniformly than if it is raked into windrows as is
customarily done for baling.

ENGINE Refer to the engine operator's manual for
instructions covering break-In, operation, lubri-
cation and maintenance of the engine.
ENGINE SPEED
Always run the engine at full throttle (2250 rpm
no load or 2100 rpm full load) when oper- ating
cuber.
STARTING THE ENGINE NO'T'E Both values on the
fue I tank must be open. 1. Disengage the main
cluteh by moving lever to rear position.
STOPPING THE ENGINE
To stop the engine, disengage die ring clutch and
place gearshift lever in neutral. Pull throt- tle
lever all the way to the rear and let engine run
for four or five mlnutea. Turn off the switch key
and pull up the engine stop control. If the
engine fails to stop, pull up the emer- gency
engine stop control.
2. Shlft transmission gearshlft lever to the
neutral position.

1. Position the engine atop luiob In the down
   (lower) posltlon.
2. Move the throttle lever one-half forward.
3. Turn on the key switch and press the start- er
   button. Do not depress starter Dutton for more
   than 15 seconds at a ttme. To do so may overheat
   the starter.

NOTT's. y emeryezzcy egYm stop control is used,
it ia necessa to recooh the damper ox the
eiigYzze, after malting needed repoxs, before
tfie engine can be charted again. STAR TING THE
CUBER The crop mu8t be dry enough to cube.
Experi- ence will soon glve you the ability to
estimate accurately the moisture content of your
crop. Ftll the water tank.
6. E the engine does not start, check to be sure
both stop buttons are down and the air shut- off
on the engine 1s in the cocked position. (8ee
Page 35. ) Let the starting motor cool at least
one minute then repeat starting procedure. NOTE
If the engine does not start after three or four
rt/empis, apply aIz preeoure to tW / land to
force the fuet to the engine white the starting
motor is engaged. Apply pressure to daub
siinifarfy i/ eider the fuel tank or fuel filters
have been emptied.
CAUTION Run engine at fulI throttle before
engaging main clutch and feeding material Into
the machine. Failure to do thl s may result In
stalling the cutterheod and damaging the cutter-
head drive belt. Slowly move the main clutch
lever forward, over center, engaging the main
clutch to operate pickup, feeder, and press
wheel. Check to see that all components are
running freely. Engage the conveyor clutch to
start the con- veyor and elevator.

• As the engine begins to run, check to see that
  the oil pressure gauge is registering oil
  pressure. If not, stop the engine and determine
  the cause.
• After the engine has run for a short period, move
  the throttle lever rearward to a slow idle
  position.
• ENGINE WARM-UP PEIIOD
• Allow the engine to warm up to operating
  temperature before operating under load.

Always run the engine at full throttle (2100 rpm,
load speed) when cubing hay.
Select a low ground speed (first or second gear)
that will not overload the machine. Lower the
pickup and move into the wlndrow. Travel the same
direction as the wlndrower traveled when the crop
was cut.

O/'ero/ion 1 j STOPPING THE MACHINE
STARTING THE CUBER Contlnued Spray a small
amount of water on the wlndrow tf the dte
opentngs are empty. E the dte openings are full,
do not spray any water on the wlndrow until
cubes start to move out of all the dte open-
tngs. Frtctton from the hay will cause the dte
ring to heat up to about 175 F. , which 1s
operating temperature. Thts wtll require 5 to 10
minutes depending on crop condtttons and alr
tempera- ture. Do not attempt to finalise the
epray setttngs unttl the dle rtng has reached the
operating tem- perature. During the "warm-up"
pertod a lxitld- up may occur tn the dies. Tlits
buildup wt11 move out faster and easler tf spray
ts reduced 8ome "flnes" can be expected durlng
the "warm-up" pertot. When the dte rlng has
reached the operattng temperature, adjust the
spray so machine wlll form a hard, dense cube
that breaks off cleanly and uniformly when tt
contacts the cube deflector. The operator can
check cube quality by ez- amtnlng them as they
emerge from the dte rtng. Cubes containing too
much water wttl tend to curve out from the
deflector and not separate. Cubes that nake off
tnto "Ilnem" before con- tacting the defleotor
require more water. At the end of the wtndrow,
shut off the noszle selector valve and disengage
the conveyor clutch. Thls wlll prevent the loss
of water and the loss of cubes comfng from the
elevator. As the machine enters the next wlndrow,
start the epray on the first hay to enter the
ptekup. Engage the conveyor clutch as soon as the
tratl- Ing vehicle 1s tn llne wttli the hay cuber
and under the elevator hook
When stopping the machine at the end of each day,
shut off the nossle selector valve to stop the
spray about 50 feet from the end of the wind-
row. This wtll permtt the dtes to be ftlled with
hay that ts too dry for eubtng but thts hay can
be moved easlly out of the dies when starting the
next morning.
TRANSPORTING Ratse ttie plclrup as htgh as
possible and lower the elevator when transporting
hay cuber. Grease clutch shaft when transporting
ma- chtne a long distance. See Lubrtcatton
Charts. When transporting the cuber on a road or
highway at ntght or durtng the day, use ltghts
and devtc es for adequate warning to the
operators of other vehtcles. In thls regard check
toeal governmental regulattons. Various safety
llghts and devlc es are available from your John
Deere dealer. NOTE The flashing warWng lamp
con be wizad to 6utti contfnttously when light
switch is OF i.f flashing lights are
prohibited b y local ragulatlotrs. Connect the
two wiresgoing into ffie flashes null to the same
terminal. Take wire off one terminal and attach
to other wire, b ypassi t'e terminal. See Wring
Diagram, page 54.
CUBE STORAGE
Fresh cubes are motet and warm. They should not
be stored In an enc losed bulldtng until they
have cooled and dried sufftctently to allow safe
storage. When good quality, dense cubes are
betng formed by the machine, storage wfll not
normally be troublesome, because moisture will be
from 12 to 15 per cent. However, poor qualtty
cubes, those made with the addition of excessive
mois- ture or those made from the hay whtch has
not been sufficiently drted, may allow the
formation of mo1-L Under certain conditions, It
may be advisable to allow cooling and drying of
the cubes In smalt lots (truck dumps) on an
outdoor slab for a few days prtor to storage In
enclosed areas. When- ever a doubt exists as to
the safekeeplng quali- ties of the cubes, this
practlc e should be fol- lowed.
NOTE I,f you forget to engage the conveyor
clutch a /torn will sound when cubes me aecumu-
dated in the conveyor under the die ring. SEL
ECTING PROPER GROUND SPEED Always run the engine
at full throttle. The ground speed can be very
closely controlled by uslng the selective ground
speed drtve In con- junction with different
transmtsston speeds. Select the best transmission
speed range then, wtth the selective ground
speed control lever, adjust the ground speed to
meet fteld conditions. When wlndrows are prepared
tn proper width, optimum operattonal speeds wtll
be between 3 and 4 mph. In thls speed range,
the ptckup w111 gather the wlndrow Into the
machine with a mini- mum of agttatlon to the
crop.

UNIT AND CRANKCASE
END OF THE REASON SERVICE Foliow the suggestions
on thts page to be sure your cuber is ready for
operation when the next season starts. ENGINE Wash
the outside of the engine thorougNy. Use diesel
fuel and a stiff brush. Drain the crankcase,
flll with fresh otl ac- cording to apectflcatlona
on page 15. Run the engtne at ldltng speed for
15 to 20 minutes. Leave oil in crankcase while
cuber 1s storef.
Use the grade of oil recommended In the lu-
brication chart. Lubricants of the right
viscosity are necessary for proper protection
See page 15.
TRANSMISSION AND F'INAL DRIVES SAE 80
Multipurpose-type 8CL gear oil is recommended
for year-round use however, If oil is too heavy,
thin Frith SAE 10W oil.
Clean inaide of air cleaner, remove dirt from
filter and install fllter in air cleaner. Also
clean pre-cleaner.
COOLING SYSTEM
When the temperature 1s likely to be 32 de- grees
F. or lower, there 1s danger of the water
freeEtng In the cooling oystem. To prevent this,
either drain the cooling syatem at the end of
each day's run, or use an antlfreeze solution.
The use of antifreeEe is recommended. NOTE All
macho rz are shipped from fac- tory with
antifreeze in radiator.
DrinaflbeL If antlfreese is not Installed, drain
water by removing all drain plugs from radiator
and en- glne block. (See engine manual.) Leave
out dratn plugs so water that might condense in
cooling syatem can drain. Sweat exhaust opening,
crankcase breather, and hydraulic oil reservoir
breather with sealing tape to prevent entrance of
moisture or foreign material. If cuber 1s stored
in the open, remove battery and store in a cool,
dry place where temperature will stay alxive
freezing. Do not place battery on a concrete
floor as cold tends to draw strength from the
battery. Cheek and recharge the bat- tery every
30 days to prevent damage to the plates.
WATER TANK When there is danger or freesing and
the cuber is stopped for the day, drain the water
tank, water pump, and the strainer ar.
BAT'2ERY When the temperature drops below
freezing, take precautions to avoid damage to the
battery. A Dadly discharged batteryfreezes more
quickly than one that is well charged. For
example, a battery with a specific gravity
reading of 1.175 (discharged) will freeze at 4
degrees F. , and a battery wlth specific gravity
reading 1.300 (fully charged) will not freese
until the temperature reaches -65 degrees F. In
freezing weather, do not add water to the battery
unless engine is going to be run long enough (2
or 8 hours) to assure a thorough mix- ing or
water and electrolyte.
Remove radiator screen and clean out any dust or
dirt accumulated in the radiator core. Use air or
water, under pressuFe, for this purpose. Install
new oil filter element and gasket. Drain fuel
fiiter and strainer. Remove re- taining bolts,
shells, and elements. Discard old elements and
gaskets. Wash shells in clean fuel oil and insert
new elements. Fill the cavity be- tween element
and shell about 2/3 full of clean fuel oil and
reassemble.

SAFETY SUGGESTIONS
The safety of the operator was one of the prime
considerations in the minda of John Deere
engineers when this cubing machine was de-
signed. Shielding, simple adjustments, and other
safety features were built into the machine
wherever possible.
Provide a first-aid kit for use in caee of ac-
cidents, and use proper antiseptics on scratches,
cuts , etc., without delay, to prevent the possi-
bility of infection.
Usethefiandralwhen mountingordismount- ing from
cuber. Be especially careful if operating on
hillsides, because the cuber may tip sideways if
it strikes a hole, ditch, or other irregularity.
You can make your farm a safer place to live and
work if you observe the safety suggestions given.
Study these suggestions carefully and in- sist
that they be followed by those working with you
and for you.
Make sure everyone is clear of the cuber before
starting so they will not be struck by moving
parts or caught in a drive belt or chain.
All machinery should be operated only by re-
sponsible persons who have been d9legated to do
Never attempt to clear obstructions unless the
cuber is stopped and the engine shut off.
Never clean, oil, or adjust the cuber when it is
running.
Lower the elevator when transporting.
Refill the radiator only when the engine is
stopped or idling slowly. This engine has a
pressure cooling aystem. To avoid being scalded
when radiator cap iS removed, first turn cap
slightly to the stop which allows steam to es-
cape through the overflow pipe. After all pres-
sure is relieved, remove cap.
Have a fire extinguisher handy. It's a good idea
to mount one on the operator's platform.
Replace badly frayed or worn belts before
they break.
Clothing worn by the operator should be fair- ly
tight and betted. Loose jackets, skirts,
shirts, or sleeves should never be worn be-
cause of the danger of getting into moving parts.
Refuel only when the engine has been shut off. Do
not smoke or use an oil lantern when refuel- ing.
Keep the engine clean of chaff and straw to
prevent the possibility of fires.
Never leave the hand crank on the die ring in-
put stiaft or cutterhead shaft. Never use the
hand crank, unleaa the engine 1s stopped and the
matn clutch is disengaged.
Be sure the gearshift lever is in neutral be-
fore starting the engine.
When trangporting the euber on a road or
highway at night or during the day, use llghts
Keep the operator's platform clean. Do not use
it as a place to carry loose tools, lunch
boxes, etc.
and devices for adequateraming to the oper-
ators of other vehicles. In this regard check
local governmental regulations. Various safety
lights and devices are available from your John
Deere dealer. Inareas where flashlng lights are
prohlbited Dy loeal regulattons, be sure the
flash- er for warnlng lamp is dlscorinected. (See
wlrtng diagram, page 54. )
Be sure shields and guards are in place and in
good condition before starting in the field.
The brakes should be properly ad)usted.
Always keep the cuber in gear when going doen
hills.

FUELS AND LUBRICANTS
DIESEL FUEL OIL SPECIFICATIONS
Engtne operation at altitudes above 5000 teet
requl res use of next lighter class of fuel oil
than would normally be used.
The quality of the fuel oil used for high-speed
diesel engine operation is a major factor foi
sat- isfactory engine performance and life. The
tuel oils selected must be clean, completely
dtstilted, stable, and non-corrosive. DISTILLATION
RANGE, C ETANE NUMBER, AND 8UL FUR CONTENT are
three of the most important properttes in the
selection of dlesel fuels for optimum
combustion and mtnimum wear. Engine apeed,
load, and atmospheric tem- perature Influence
the selectton of the fuels mth respect to
dlstiltatlon range and cetane number. THE SULFUR
CONTENT OF THE FUEL MUST BE Afi LDW AS
POSSIBLE, to avoid excessive deposit formation
and premature wear.
During cold weather engine operation, the '
'cloud point' (the temperature at which wax c
rystals begln to form in the fuel oil) must be
below the towest expected air temperature to
prevent clogging of the fuel fitters by wax
crystals.
At temperatures below -20 F. consult your GM
Detroit Diesel sales and service outlet, stnce
particular attention must be given the cooling
system, lubricating system, fuel system, etectri
- cal system, and cold weather starting alda
for efficient engine operation.
BEARINGS
Diesel fuels are generally marketed accord- ing
to ASTM designation D87â-60T and only
dlatlllate fuels No. lD and 2D are considered
satisfactory for GM Detroit Detsel Engines.
These fuels should not be confused wtth the do-
mestic type furnace oils ASTM D388-80T whleh have
similar properties but are not always satts -
factory for englne use due to their varying com-
position, eetane number, and dlstlltatton
range. As a guide to the selection of the proper
fuel oil refer to the fuel oil selection chart.
Two types of sealed bearings are used on this
cubing machine. One type is a sealed bearing
which requires no lubrication the other type is
prepacked at the factory and will requt re yearly
lubrication.
GREASES SAE multtpurpose grease 1s satlafactory
for all grease fltttnga on your cubtng machine
except where other 1s spectfted the special
heavy-duty, high-temperature grease (Shell
Darlna AT, or equtvalent) specified for the
press wheel and other locattons 1s highly
recommended.
