SPECIFICATIONS
The John Deere BW, BWN, and BWS Disk narrows are
double ac- tion, heavy duty, rigid, wheel-car-
ried disk harrows. They can be used with John
Deere Tractors equipped with an 8-inch stroke
remote hy- draulic cylinaer, or any other trac-
tor using an 8-tnch stroke remote hydraulic ey
linde r that conforms to ASAE-SAE standards. On
BW Disk Harrows the disk spacing is 8- 1/2
inches. On BWN Disk Harrows the disk spacing is
7-1/8 inches. On BWS Disk Harrows the front disk
spacing is 8- 1/2 inches and the rear disk
spacing is 7 -1/8 inches. All disk gangs have l-
1/4 inch square gang bolts and double tapered
roller bearings. The angle of the gangs can be c
hanged quickly and easily, and the front and rear
gangs can be angled independently of each
other. Upper and lower cushion springs on the
Pitch absorb shocks encoun- tered when disking
and transporting. The lower spring also acts
as a Ieveling spring, which compresses when
working, and extends when the har row is raised,
keeping harrow gangs level and giving a paralleI
lift for more transport clearance. A hitch is
provided on the rear of the harrow for pulling
such equip- ment as a spike tooth har
row. DISKING DEPTH - Controlled by raising or
lowering the carrying wheels with the hydrauli
c cylinder, and the angle of the disk gangs.

• LEVELING - Adjusting hand screw on harrow
  levels the harrow tor various tractor drawbar
  heights.
• CARRYING WHEE LS - 14-inch
• wheels with automotive type, adjust- able,
  tapered roller bearings. 15- inch wheels are
  optional.
• WHEE L TREAD - 80 inches when wheels are

  when whee Is are mounted on outside ot whe e1
  frame.
• DtlA L WHEE LS - Dual wheels are regular on
  the 17-toot, 10-inch - 19-foot, 2-inch - and
  20-foot, 6-inch BW Disk Harrows. They are avail-
  able as special equipment for all other sizes
  except the 8-toot, 6-inc h and the 9-foot,
  10-inch BW Disk Harrows.
• DISK BLADES - Regular or Cone
• - 18-inch, 20-inch, or 22-inch soltd or cut-out
  disk blades are avallable.

  rear gang outer disk blades. 14-, 16- or
  18-inch disk blades are recommended for this
  attachment, depending on size of disk blades on
  aisk har row. (See page 10. )
• HITCH LOOP - Optional for use on disk harrow when
  tractor draw- bar is equipped with hammerstrap.
• END SCRAPER ATTACHMENT -

OPERATION
5
When detaching the disk harrow from the tractor,
be sure the disk har row is in the raised
position and the remote hydraulic cylinder hoses
are disconnected before pulling the drawbar pin
and driving the tractor away from the disk har
row. TRANSPORTING Use the transport link to
hold disk harrow in a rai Sed position for
transporting or storage. TRANSPORT Li NK
PRE PARING DISK HARROW Inflate the disk har row
tires to 30 pounds pressure. Lubricate the disk
harrow as in- structed on page 13. The BW, BWN,
or BWS Dlsk Har- row can be used with any
tractor equipped with an 8-inch stroke re- mote
hydraulic cylinder that con- forms to ASAE-SAE
standards. PR EPARING TRACTOR Refer to your
tractor operator's manual for wheel weighting
instruc- tions and tire inflation pressures. On
John Deere 2010, 2020, 2510, 3010, 3020, 4010,
4020, 5010, or 5020 Tractor equipped with
rear rockshaft, set the selector lever in the
D position. If the tractor has an adjustable
swinging drawbar, position it in the long, low
position. ATTACHING TO OR DETACHING rROM
THETRACTOR The disk harrow must be in the raised
position before attaching it to, or detaching
it from, the tractor drawbar. Back the tractor
up to the disk harrow, install the remote
hydraulic cy linder on the disk harrow, and place
the hoses in the hose holder. If the disk
harrow is not in the trans- port position, raise
it with the cy1- i nder and attach the disk
harrow drawbar to the tractor drawbar.
PN
To connect the transport link (1) Fully extend
the remote hydraulic cylinder. (2) Alemove the
pin from hole ' 'A. Line up the slotted hole in
the end of the transport link with hole B, and
install the pin. NO TE.. If desired, the rein ofe
hy- draulic c ylinde r can now be reinoved and
the dish f2orrow riff stoy zn the raised
position. Lock the tractor swinging draw- bar in
a fixed position. Do not transport the disk
harrow over 12 miles per hour on a smooth surface
road, and reduce the speed considerably when I
raveling over rough ground.

TRAC TOR SWINGING DRAWBAR
For best results when dishing, the tractor
drawbar should be free to swing. EXTENSION

working position on the 16- foot, 6-inch BW,
17-foot, 10-inch BW, 19-toot, 2-inch BW, or
20-foot, 6-inch BW Disk Harrow'.

• CAUTION
• Extension gangs have spring lift. Stand clear
  when folding for transport.
• A I w a y s secure extension gangs in transport
  position with locking device.

sure they are tight.

the leveling cam clock- wise to lower
extension gang or counterclockwise to ratse

locking bar.
ADJUSTING DISHING DE PTH
The depth of disking is controlled by the remote
cylinder control lever of the tractor and the
angle of the disk gangs. The transport weee Le
will act as gauge wheels to regulate the working
depth of the disk har- row. After determining
the correct disking depth as regulated by the
transport wheels, position stop on remote
cylinder so transport wheels raise to same
position each time. See tractor operator's
manual. For maximum penetration, set the
gangs at a tull cutting angle and raise
transport whe eIs completely o R the
ground. For iess than maximum penetra- tion lower
the transport wheels to raise the gangs or
reduce the cut- ting angle of the gangs.

ADJUSTING SCRAPERS
Adjust the leveling screw on the drawbar as
follows to level the disk harrow and to obtain
uniform pen- etration of the front and rear gangs.
One-piece scrapers are regular equipment.
Two-piece spring loade d scrapers are
optional. The hole s in the top of
each scraper bar are slotted so that by adjusting
the scraper bar you can move all the sc rapers
on the bar in or out at one time. Also, the hole
for each sc rape r is slotted so each sc raper
blade can be adjusted in- dividually. Widen
scrapers are required, ad- just blades so the
scraping edge of each scraper blade is flush
against the disk blade but not tight enough to
prevent the gang from revolving freely. When sc
rapers are not required adjust the scraper
bars to move scraper blade s away from the disk
blades.
Shortening the leveling screw (turning
clockwise) will raise the rear section.
Lengthening the lev- eling screw (turning
counterclock- wise) will lower the rear section.
NOTE Be sure nut end jam nut on leveling screw
are both snug against the doffom of the sprtrzp

To angle the rear gangs, remove the angling
device from the front gangs and attach it to the
rear gangs.
Remove the retaining pin and pull the angling
lever to the rear to de- crease the angle, and
push the an- gling leve r forward to increase

When the desired angle has been obtained,
replace the retaining pin.
When the desired angle has been otitained,
replace the retaining pin. WHEELTREAD The wheel
tread is 80 inches when wheels are mounted on
inside of wheel frame or 120 inches when
wheels are mounted on outside ot wheel frame.

ADJUSTING REAR GANGS LATERALLY
The variations in soil from one field to
another, and sometime s in the same field, can
have an effect on the way the rear gangs level the
The rear gangs can be set in a wide or narrow
lateral position. Certain lie Id conditions,
blade sizes, or tractor speeds may make it
necessary to change this lateral position to
eliminate a ridge or fur- row between the rear
gangs.
The middlebreake r attachment (BB1206 7) is
available as special equipment to remove the
center strip left by the front gangs. If the disk
harrow is equipped with 18- or 20-inch disk
blades use holes 'A and ' C.' ' If the disk
harrow is equipped with 22-inch disk blades use
holes ' 'B and D, as illus- trated.
For 18- and 20- inch tilade s holes ''B' will
usually be most satisf ac- tory. For 22- inch
blade s it may be necessary to use holes 'A' '
if tire disk harrow is run in full angle.
