INTRODUCTION
There ie a RIGHT WAY
WRONG WAY to do everything
Your new John Deere No. 50 Forage Blower is a
dependable machine, but only by proper care and
operation can you expect to receive the service
and long life designed and built into it. Like
any precision machine, your blower will require a
certain amount of attention at regular intervals.
When any questions arise regarding lubrication,
operation, or maintenance, use your manual as a
guide to service your machine the RIGHT WAY. If
you find yourself in need of additional
information or special servicing not covered in
this manual, see your .John Deere dealer. He is
in a position to answer your questions for you,
or to secure the correct information. When in
need of parts either to replace worn parts or to
make emergency repairs, see your local John Deere
dealer he and the John Deere branch house behind
him are equipped to render prompt service
during the long life of your blower. When
ordering parts, give your blower serial number as
well as the part number and description provided
in the parts list of this manual. This
in- formation will help him give you prompt
and ef- ficient service. The serial number of
your blower is located on the rear side of the
hous- ing above the drive pulley. (Record tt in

OPERATION AND ADJUSTMENTS Before using your new
John Deere No. 60 Forage Blower, make sure that
all bolts are tight, cotter pins are spread and
machine has been properly set up. Be sure machine
is thoroughly lubricated as shown in lubrication
chart, pages 12 and 13. The blower must be as
near the silo as possible. To change the blower
from transport to operating position, remove one
bolt from each wheel hanger. Push wheels forward
so stub azle will rotate in retracting slot. This
lowers the blower into operating position. Save
bolt by replacing it in frame end plate. The bolt
is used to lock blower in trans- port position.
Unhook transport chains so auger may be raised to
allow wagon to pass. Drive two stakes in the
stake pockets to hold blower in position. Be sure
the machine is level, so blower pipe runs
straight up. PIPE AND DEFLECTOR. Bolt the
required length of pipe and detector securely
together. ( NOTE The inside rounded ends of the
ptpes should 9o touiard thp T0fliid.) XAi8
fOrrriB a smooth surface and allows the material
to flow freely through the pipe. In order to
raise the pipe, attach a rope and pulley at the
top of silo near the opening or door. hasten one
end of the rope securely to the center of the
pipe sections which have been bolted together.
Take a half-hitch around pipe about 8 feet from
the upper end and elevate pipe into position.
The pivot pipe on the blower outlet will permit
connecting at the angle neces- sary to reach the
silo. SECURING BLOWER PIPE. After pipe is in
position, wrap rope around one of the frame
angles three or four times and tie. Be sure upper
end of pipe is fastened securely to silo.
8
OPERAT ION AN D ADJ USTM ENT 5 If no other
provision is made, two boards can be nailed into
a V, set around pipe, and nailed to top of
silo. The blower pipe should go up as straight
as possible to eliminate side friction.
Unnecessary friction reduces the efficiency of
the blower. BUCKET PIPE AND DISTR IBUTOR PI
PE. By using a bucket pipe and distributor pipe,
the flow of the silage may be directed to any
part of the silo. In this way the silage will
be more uniformly packed. After blower pipe is
raised and secured firmly to the silo, attach
another rope and pulley on inside of silo near
the end of de- fector. Use rope on inside of silo
to raise bucket pipe. While raising bucket
pipe attach required lengths of distributor pipe.
Attach bail or bucket pipe to the hook on top of
the deflector.
TRtB
ELBOWS. When blowing dry hay it is advisable to
bolt two 45 elbows and an adjustable elbow to
the top of the blower pipe. In some cases it may
be necessary to use only one 43 elbow. See
illustration at right.
OPERATION. After the tractor is in position so
the blower and tractor pulleys are in alignment,
place drive belt on pulleys and back tractor
into the belt until belt is tight. Set the brakes
on the tractor, or, if necessary, block rear
tractor wheels to keep belt tight and in
line. Engage clutch slowly at first to make sure
belt is running true and that the blower turns
over freely. Then open throttle on tractor and
let blower run at operating speed for several
minutes. Start feeding material into the auger
slowly at first until paint is worn off the in-
side of housing and pipes. If undue slippage is
noted

strand opposite idler deflects 1/2-inch when 15
pounds pressure is applied half-way between both
pulleys. DRY HAY. When adjusting the doors for
dry material the small feed opening door should
be fully down in its slots and the large feed
opening door should be opened half way. In this
initial setting the air door should be completely
closed. Use the small sprocket on the auger drive
when blowing dry material. (See auger sprocket
adjustment, page 7.) The fan should run at 800 to
1000 revolutions per minute. When the machine
is running, gradually open the large feed
opening door until the fan is accepting its full
capacity. After the best feed opening size has
been determined raise the air door one inch at a
time until the material is blowing freely and the
machine has reached ite peak of capacity.
ENSI LAGE AND GREEN HAY. When adjusting the
doors for moist material the large feed opening
door should be fully down in its slots and the
9ma11 feed opening door should be about half way
open. In this initial setting the air door should
be com- pletely closed. Use the large sprocket on
the auger drive when blowing moist material. (See
auger sprocket adjustment, page 7.) The fan
should run at 800 to 1000 revolutions per
minute. When the machine is running, gradually
open the small feed opening door until the fan
is accepting its full capacity. After the best
feed opening size has been determined raise the
air door one inch at a time until the material
is blowing freely and the machine has reached its
peak of capacity. NOTE Once these adjustments
have been made keep in mind that when the Jeed

of the sprock et s. The Iarge sprocket goes
inside and engages the chain when handling moist
material. Using the small 21 tooth auger sprocket
for dry material with the fan turning 800
R.P.M.s, the speed of the auger is 163
R.P.M.s. If the fan speed is raised to the
maximum of 1000 R.P.M.s, the auger speed will be
204 R.P.M.s. When blowing moist material, using
the 31 tooth sprocket, with the fan running 800
R.P.M.s, the auger is slowed down to 111
R.P.M.s. At the maximum fan speed of 1000
R.P.M.s, the auger speed is 138 R.P.M.s. AUGER
STRIPPER. To prevent material, especially green
hay, from wadding and wedging between stripper
edge and auger flight, adjust stripper close
enough so it will just clear auger flight when
auger is completely rotated.
BLOWER FAN SPEED. Blower fan should operate from
800 to 1000 R.P.M. in average conditions. Other
conditions being equal, the lower speed is
practical to elevate dry chopped hay and corn
ensilage and the higher speed for green chopped
hay.

OPERATION AND ADJUST M ENT
FAN AND BEARINGS. Keep the bearing housing
filled with a good grade of gun grease.
Tapered roller bearings in this housing should
be tightened when there is a noticeable amount
of end play in the fan shaft. To do this, remove
the cotter pin at the fan end of shaft and tighten

nut until a drag is felt when the shaft is ,
turned. Back off nut one eastellation and
replace cotter pin. The clearance between the
fan blades and the housing rim is set to close
tolerances at the factory and ordinarily
should not require changing. If for any reason
the main bearing housing is removed, chart the
quantity and position of the horseshoe shims
under each of the four bolt holes. Unless there
is more than a 3/32 clearance between the fan
blades and the bottom of the housing replace the
bearing identically as it was before. If this
clearance is more than 3/32 remove one or more
shims from under each of the four bolt holes
as is necessary.
CLUTCH AND CLUTCH LEVER. The step-notched
collar is adjusted to one of three positions to
keep the slid- ing clutch properly en- gaged
with the stationary clutch. Rotate collar to
increase or decrease ten- sion of the clutch
spring. Clutch Iever shi fter yoke should not
bind on clutch face when engaged causing undue
wear. En- gage clutch and adjust by loosening and

PULLEYS FOR VARIOUS TRACTORS TO OBTAIN BLOWER
SPEED OF APPROXIMATELY 900 R.P.M. To determine
the proper pulley for your blower, find the
diameter of your tractor pulley, to the nearest
one half inch, at the top of the graph and the
speed of your tractor pulley, in revolutions per
minute to the nearest 50, down the side of the
graph. Carefully trace the lines from these two
figures into the center of the graph to where
they intersect. The zone in which the lines
intersect determines the size of pulley to use on
the blower. To figure exact speeds of blower fan
using the pulley recommended tn chart below,
use formula shown on page 10. TRACTOR PULLEY

HOW TO FIND SPEED OR DIAMETER OF PULLEYS. The
diameter of the tractor pulley multiplied by the
speed of the tractor pulley divided by the
recommended speed of the blower pulley will give
the size pulley necessary for the
blower. Example The drive pulley on the tractor
is 13 in diameter and runs 975 R.P.M. and the
desired speed of the blower is 900 R.P.M. 13 X
9(S 12675 12675 900 14 (approx.) A 13-1/2
pulley should be used on the blower. If the
diameter of the blower pulley is known and the
resulting speed is wanted, multiply the diameter
of the tractor pulley by the speed of the
tractor pulley. Divide the resulting product by
the diameter of the blower pulley to get the
speed of the blower. Example The drive pulley on
the tractor is 13 and runs at 975 R.P.M. and the
blower pulley is 13-1/2 diameter. 13 X 975
12675 1?67S 13-1/2 938 R.P.M. The blower
speed is 938 R.P.M. BELT. For best results, a
4-ply 6-inch wide 50-foot endless belt is
recommended. Do not use a sticky belt dressing,
as it collects on the pulleys and increases the
pulley sise, causing vibration and loss of
speed. Ask your John 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 blower
and the tractor. Place it so it just clears the
belt when the blower is not being operated.

OPERATION AN D ADJ UST M E NT TRANSPORTING
BLOWER. To transport blower, hook up both auger
chains and attach blower tongue to tractor.
Obtain a hard wood stick 1-1/2 x 1-1/2 x
21-1/2 and cut a 3/4 taper at one end. Place
square end of stick under front of upper frame
end plates and rest sharp edge of tapered end on
ground. (If ground is soft use a flat board under
sharp edge of stick to prevent end from burying.)
Remove wheel hanger bolt from frame end plate
(see illustration, page 4) . Drive tractor
forward slowly and allow blower side to ride up
on stick high enough for wheel to turn dovmward
in retracting slot. Replace wheel hanger bolt,
see illustrations on page 4. Repeat the above
procedure to raise op- posite side of blower.
STORAGE. Before storing your blower, carefully
inspect machine for worn and broken parts. These
should be adjusted or replaced, thereby saving
costly delays when blower is needed the most. The
service you receive from your blower depends on
the way it is taken care of when not in use, as
well as when operating. When the season is over,
thoroughly clean and lubricate all parts of the
machine. To protect your stored blower from the
elements, repaint any places where paint has worn
or chipped off. Coat exposed working parts with
rust preventive. Store your blower inside a
building whenever possible. Otherwise,
cover blower properly to protect it from the
weather. Jack up blower to take load off tires.
Do NOT remove air from tubes. PNEUMATIC
TIRE8. Your blower requires pneumatic tires. Two
5 90 x ISO-ply implement tires are supplied as
optional equipment. Keep inflated to 22 pounds
pressure.
