LUBRICATION G E N E R A L The economical and
efficient operation of any machine is dependent
upon regular and proper lubrication of all moving
parts. The bearings on this mill are a close fit
to give longer life. Best results can be obtained
by using a high grade of gun grease of the type
listed below, which ie suitable for all bearings
on the mill. Too much gun pressure on the ball
bearings will cause them to heat. Wipe dirt from
fittings before greasing. Lubricate all parta
thoroughly but avoid excessive lubrication.
Excessive lubrication will allow the excess
lubricant to collect dirt. If a grease fitting
becomes lost, replace it immediately. Keep
governor parts well oiled. U S E B E S T G R E A

OPER A TIN G INSTR UCTIONS The mill should be set
either permanently or put on skids so it can be
moved from one location to another. In either
case, the mill must he an- chored solidly before
the power is applied. A N C H O R S T A K E
S Since rigid fastening is necessary to properly
operate the mill, we have available eteel anchor
atakes which are very satisfactory. The
part number is J15479C. The stakes are supplied
as extras when ordered. Two stakes, J 8479C,
should be ueed on the pulley side and one on the
opposite side, to hold the mill down firmly in
alignment with the tractor pulley. Each stake
should be driven at an angle to within a couple
of inches of top of skid. Then bolt on the cross-
bar and finish driving both sides, Figure 1. B E
L T When using a tractor, a 50-foot endless
hammer mill belt, not less than 6 inches wide,
should be used. A longer belt will be found more
practical. Do not use a sticky belt dressing, as
it collects on the pulleys and in- creases the
pulley size, causing vibration and foes of
speed. A thin liquid dressing stops slippage and
preserves and softens belts. Ask your J hn Deere
dealer about a suitable belt dressing. To prevent
a belt from whipping when it is used in windy
conditions, drive a stake about halfway between
the mill and the tractor. Place it so it just
clears the belt when the mill is not being
operated. If there is belt slippage, check the
belt for teneion, alignment, and stiffnees.
Then uee belt dressing, as directed above, and be
sure the mill is firmly anchored. Be sure the
tractor speed is right. D R I Y E P U L L E Y If
pulley is changed on mill, use a wood
block to drive on the pulley until it ie against
the spacer outside of bearing. Always use a new
square lock washer and screw the nut tight as
possible with a long-handled wrench. Then lock
the out by bend- ing over a corner of the
square waeher.

• Check the traveling feed table and rotor housing
  for tools and other objects that may cauee
  trouble.
• To check the conveyor chains in feed table, use a
  box wrench on the collar at end of gover- nor
  ehaft to turn it. The conveyor chains in feed
  table ahould run with juat enough tension to keep
  the chains from climbing the sprockets.
• These sproekcte on shaft at outer end of feed
  table need oiling often.
• Open rotor hood. The cutterhead, rotor and fan
  ahafta have all been run and tested at the
  factory arid left there in correct adjustment. To
  check these adjustments for damage in ship- ment,
  revolve rotor by hand. Examine interior of mill
  body closely and remove any foreign objects
• ST A R T MI L L S L0 W L V
• Run mill alowly to make sure all drivee are
  correct and bearings do not

• The governor must be adjusted so it will stop the
  feed table when the mill pulley speed dropa below
  the rec- ommended apeed of 2800 R.P.M. when
  working under load.
• If the governor doea not cut out soon enough,
  loosen lock wing nut on in- side of bracket and
  tighten outside nut one-half turn. Cheek results
  after every half-turn adjustment. In the
  event traveling feed table cute out too soon,
  looeen the outside wing nut a half-turn and
  follow up with the lock nut.
• Be eure both wing nuts are tight when the final
  adjustment is made.
• T O A DJ U ST G0 V E R N O R D R I Y E B E L T
• To tighten the governor drive belt, raise the
  governor shaft bearings and
• lengthen drive chain on the other side, if
  necessary.
• The ezWa steel waahere on bearing bolta ahould be
  put under the bear- ings, to raise the governor
  shaft.

0 T A D J U S T F A N D R I V E B E L T When the
belt becomes stretched, remove the three
bolts in adjustable drive sheave but not the
belt. Be sure to note which aet of in- aide pada
were aeated. Turn the outside plate to the next
lower pads. Replace the bolts, turning sheave so
the bolt to be tightened is below the shaft. Turn
each nut up two turns at a time, until each bolt
is tightened equally. When all adjustments
have been secured on the upper sheave,
additional adjustment can be had by putting
belt on outer two-step aheave and moving upper
sheave out on shaft to line up with lower sheave,
turn-

ing the outside plate of the upper sheave to a
higher set of pads. This will give you eight
adjustments on the belt. Always follow this
method in changing or tightening belt so aa to
avoid damage to belt. V-Belt a should never be
forc9d over the outside of sheaves. T O CH A N G
E S C RE EN S Tilt rotor hood back and remove
breaker bar. Slide oereen out of screen
guides. Sometimes damp materials become packed in
the screen guides making the sereene hard to
remove. In thie case use a bar inserted in the
center of the acreen about halfway around so a
hammer can bump the bar. Now rock the rotor
shaft to jar the screen a few times, then the
screen can be pulled out readily. This
method will not ruin the original form of
the screen.
Inaert the new screen and replace the screen lock
with wide offset A down on screens except those
that are 3/32 thick or less. On these lighter
screens put the narrow side B down on the
screen. Close the rotor hood and tighten firmly.
14
B E A R I N G 5 When neeessar y to remove or
replace the ball bearings, a gear puller should
be used. H A II kl E R S The hammers should be
reversed as soon as worn round on the corners. If
this is done before badly rounded, new stepe can
be ground on twice, thus giving 6 good grinding
surfaces. Be sure emery wheel is trimmed for
square edgeskeep hammers cool while
sharpening. When grinding material containing
excessive sand or dirt, use special hard-surfaced
hammers which are the regular hammers coated with
a very hard alloy. These hammers will outlast
several sets of regular ham- mers. CAUTI ONWhen
hammers are taken out to reverse or grind them,
re- move only one row of hammers at a time and
replace them with the spacers and faces of
hammers arranged in the same order and position,
as in Figures 8, 9, and 10. Each row of ham- mers
is in a different position on the pins. This
rotor is very care- fully balanced, so care must
be used when grinding or replacing wtth new
hammers to have all three sets equal. Always turn
or sharpen or re- new all three rows of hammers at
Fi gure
the same time, in order to main- tain balance of
rotor. If a ham- mer or spacing washer is broken
or lost, don't run mill until a new one is
installed. The new hammer should either be
ground down to match the other worn hammers in
same row, or one new hammer installed in
each row, to maintain balance.
T O R E A S S E M B L E H A M II E R 5 Each row
of hammers should be spaced differepynote
the faces of hammers and position of spacers
and bdlance weights. If it should become
necessary to change any of the counter- balance
weights, the complete set of six should be
replaced in order to maintain balance of rotor.

• SHEAR BAR AND COMBING BAR
• When the shear bar becomes dull or worn uneven,
  it can be sharpened by grinding the edge. Be sure
  bar is ground square.
• The shear bar and combing bar are fastened to the
  ahear bar beam.
• When changing a shear bar, remove the knives as
  they will have to be readjusted later.
• Now check the teeth on the combing bar and see
  that it juat clears the
• grooves in the feed roll.
• T0 RE M O Y E T H E A SS E M B L V
• Remove the two large
• bolts at the ends of the beam.
• Remove three eerewa
• from each cover plate.
• Remove the filler cast- ings just over the enda
  of shear bar inside the mill.
• Raise shear bar beam enough so combing bar clears
  feed roll, and take it out through the side of
  the mill.
• Take three bolte out of ehear bar and remind bar
  or replace with new shear bar.
• CAUTIONBe sure ahear bar, countersunk holes,
  and beam seat are perfectly clean to inaure
  firm seating before the bar is replaced.
• Oil shear bar boIts so they may be removed easily
  when necessary.
• Tighten with a wrench on a large screw driver.

• TO USE KNIFE GRINDER
• Swing open the large guard on fan side of
  machine.
• Looeen belt tightened on cutterhead belt to put
  on grinder belt, if not al- ready in place.
• Slip the knife grinder drive belt past the
  cutterhead belt and install in the inner groove
  of rotor pulley.
• DISENGAGE HAND CLUTCH SO FEED DOLLS AND TRAVEL-
  ING TABLE DO NOT OPERATE.
• Before removing knives from mill mark them and
  knife heads eo they can be put back in their
  original places. This will cause less adjust-
  ment after they have been 8round.
• Remove knives by using a special box wrench
  furnished with the mill. Be aure wrench is firmly
  seated on nut and that all power applied to
  wrench is away from knife edge.
• Bolt cast handles to back side of knife using
  bolts and wing nuts furnished. Be sure the
  notched side of handle is on the bottom so handle
  will clear knife guide.
• Loosen wing nuts under knife guide.
• Adjust both ends of guide so that the bevel of
  knife liee flat on the left- hand surface of the
  emery wheel. Use the left-hand surface only for
  grinding. Tighten both wing nuts firmly.
• Oil groove on knife guide to insure smoother
  actton as the knife ie being ground.
• T O S H A R PE N K N I Y ES
• The mill ehould be run at the regular operating
  speed. (2800 to 3000
• With knife in guide, hold it firmly, still
  allowing it to follow the 8uide. Do not put
  unnecessary pressure on the wheel. Start left
  end of the knife on the left face of the wheel
  and make a continuous stroke to the left un tit
  tho en fire ed ge has been ground. Noher
  grind w1th e 6ocA and North motion.
• The knife should be cooled in water every
  other stroke across the grinding wheel.

  the beveled edges and corners of the hammers
  sharp. The hammers will do better work and last
  longer if not allowed to get too blunt.
• TO GET BEST SERVICE FROM THE KNIVES, FILE
  OCCASION- ALLY BETWEEN GRI NDINGS.
• REPLACING AND ADJUSTING KNIVES
• Remove drive belt from cutterhead pulley.
• Loosen lock nute and back off all six set screwe
  in cutterhead castings one-half turn.
• Bolt a knife in its respective place, tightening
  main nuts just enough to prevent the knife from
  shifting do not put lock nuts on.
• Move left edge of knife toward cutter bar by
  tightening the left-hand set screw against the
  knife until it just clears shear bar.
• Adjust the right-hand end in a like manner.
• If, while adjusting the knife, it is moved too
  far and hits on the shear bar, it may be backed
  up by loosening the set screw and tapping a piece
  of wood placed cross grain on the knife edge.
• Make final adjustment eo the 1nife will ahear
  heavy paper
• the entire length of the bar.
• Tighten both clamp bolts, using the special box
  wrench.
• Proceed with setting the two remaining knives.
• Install and tighten lock nuts on all clamp bolts
  and set ecrews.

• The tension on the springs should be adjusted for
  different kinds of feed. When grinding ear corn
  from the traveling feed table, take off all
  spring tension.
• Maximum spring pressure is needed when grinding
  green materials for eilage.

When it is desired to add ground grain to the cut
roughage, feed the roughage in the regular way
and introduce the grain through the gra in
hopper. The amount of grain can be governed by
the adjustable feed gate. CLOGGED FEED THROAT If
there is more roughage fed to the mill than can
pass under the com- pression web, the feed table
and compression web will stop and a clicking
noise will be heard if the mill is still up to
9peed. To clear feed throat Push eafety clutch
lever out of gear. Use a box wrench on the collar
at end of governor shaft to turn it. (See Figure
3.) Turn the governor ahaft backwards until the
overload can be removed. Dull knives can also
cause clogging. CH O P P I N G D R0' R U G H A
G E When chopping dry corn fodder and imilar
types of feed, we suggest that the hammers be
left in the mill and a 1-1/4 screen used. If
roughage containing grain such as Sorgo, Hegari,
Maize or Kaffir is being ground it may be
necessary to use a screen with smaller openings
to crack the grain. NOTE All dry roughage
contains come grit which soon dulls the
knives. In eome sandy locations, the knives need
to be sharpened after chopping five or six
tons. The knives can be filed sharp twice before
it is usually necessary to re- grind them. SHARP
KNIVES, properly set to a good edge of the shear
bar, will save wear or stretch on the belt and
require less power. C U TT I N G H A 'Y When
cutting hay, a 1- I /4 screen should be used for
a uniform coarse job. For finer grinding or for
cracking the beans in soybean hay or like
matertal, it will be necessary to use a screen
wtth smaller openings. Hay should be pitched on
the outer end of the feed table and lapped over
the hay going into the throat ahead. This will
prevent bridging and give greater capacity. Use
the 7- or 11-Tooth sprocket on end of governor
shaft, depending on length desired. To prepare
alfalfa in a meal form, a 1/16, 1/20 or 1/32
screen should be used. Either of these screens
will give a very fine uniform job. You must feed
slower into the mill for these sire screens.
(When using these lighter screens, you will find
that they will wear much longer if you place a 1
or 1-1/4 screen underneath them for additional
support.)
