Operation

• Lubrication
• Be sure prow has been properly lubricated. See
  Lubrication Charts on pages 24-25.
• Tire Inflation
• Check tire on rear wheeT to be sure it is
  infated to 43 psi.
• PREPARING AND ADJUSTING
• THE TRACTOR
• for complete tractor operating
  instructians,refer to your traclor operator's
  manual.
• Tire Inflation
• Inflate the tractor tires as recommended in the
  tractor operator's manual.
• Tractor Orawbar
• Set the tractor drawbar in the short high
  position.
• Rear Wheel Setting
• Adjust rear wheels of the tractor equidistant
  from the center like of the tractor to inside
  edge of tire.
• When using the regular category 2 or category 3
  hitch, set rear wheels at 36 inches measuring
  from the center line of tractor to inside edge of
  each tire.

• IMPORTANCE OF PROPER ADJUSTMENT
• Your new plow is fully adjustable and, when
  proper- ly adjusted to operate in the type of
  soil and held con- ditions on your farm, it will
  do a good job of plowing at a minimum of expense.
  A well-adj usted plow pulls lighter its furrow
  slices are uniform in width and depth it covers
  trash it leaves the soil in proper con- dition
  to be worked down into the best-type seedbed.
• Improper adjustment results in rapid wear and
  possible breakage of parts, and inefficient
  operation.
• PREPARING TFIE PLOW
• Plow Bottoms
• The polished surfaces of the plow bottoms have
  been painted with protective black paint.
• In most cases it is not necessary to remove the
  black paint because it will wear off quickly upon
  con- tact with the soil. In those soils where the
  black paint will not wear off, remove with diesel
  fuel.
• I f the plow is not to be used immediately,
  protect the polished surfaces by applying a coat
  of cup or gun grease. If the plow is to be put in
  storage for a consi- derable length of time, see
  pages 26-28.
• Bolts and Set Screws
• Before starting to work with a new plow or one
  which has been stored, check to see that all
  bolts and set screws are tight and all cotter
  pins spread to keep them from falling out. Check
  the bolts that hold the plow bottoms to see that
  they are drawn up tight.
• A good practice is to check for loose bolts,
  screws, or parts when lubricating the plow. Loose
  bolts are easily lost or cause excessive wear on
  parts, resulting in possible damage to the plow.

4 Operation
Front End Weighting Tractor front-end weighting
is necessary for maxi- mum field performance.
the rear wheels. This type of weight can be
secured from your John Deere dealer.
For maximum ballast, refer to your tractor
opera- tor's manual.
4020 Tractor The tractor requires a full
complement of front end weights to avoid possible
front end tip-up. See your tractor operator's
manual.
3-Point Hitch and Hydraulic System Once the plow
is attached to the tractor 3-point hitch, the
depth or load is maintained by the tractor
hydraulic system according to the setting of the
rock- shaft selector lever. See your tractor
operator's man- ual for complete explanation of
the hydraulic system.
4520, 5010, and 5020 Tractors When draft load
exceeds pull available in 4th gear, additional
front end weight will be required for proper
control while working. A maximum of front
weights, plus solution in front tires may be
added.
Ali Tractors If more front end stability is
required, lower the plow hitch assembly. See
"Vertical Hitching on page 11. Rear Wheel
Weighting Rear wheel weights may be necessary to
eliminate excessive wheel slippage or for
stability in rough or hillside fields. However,
weights should not be added to the point where
all slippage is eliminated. To do so would hinder
maximum performance of the tractor.
Sway Blocks India//eb ro Eliminate Side Sway
(5020 Tractor illustrated,'
The ideal amount of added weight can be deter-
mined by o.bserving the tracks of the rear
wheels. When the tractor is puliing its rated
load. the soil be- tween the tire lugs should be
broken or shifted. If too much weight has been
added, the tread marks will be clear and
distinct. If too little weight has been added,
the tread marks will be entirely obliterated.
The sway blocks should be set in the down and
wide position. This setting permits the plow to
hold the proper width of cut and eliminates sway
when working in the field. Since .the plow rear
wheel is steerable, the tractor draft links
should be maintained rigidly behind the tractor
for quick and positive ma- neuverability, both in
the field and in transport.
Liquid Weights Water and calcuim chloride
solution is an economi- cal means of adding
weight to rear wheels. Calcium chloride is
recommended rather than water as it will not
freeze. See your tractor operator's manual or
your John Deere dealer.
Cast-Iron Weights Where weight in addition to or
in place of liquid weight is required, cast-iron
weights can be bolted to

Remote Cylinder Operating Lever for Rear Wheel
Control The remote cylinder operating lever
adjacent to the roc kshaft control lever which
controls the rear wheel must be placed in the
float position to prevent a build- up of air
pressure in the rear wheel hydraulic cylinder. An
air pressure build-up will cause the rear of the
plow to run shallow.
4020 (aerial number 201,000 and adored and 4S0
tractors
SI
To place remote cylinder operating lever in float
position, see your tractor operator's manual.
Rockshaft Control Lever Height Stop Lock When
transporting, the front and rear of the plow
should be approximately level. To insure against
raising the hitch too high, it is necessary to
use a height stop lock for the rockshaft control
lever.
4030 (6elow seria/ number 201,000), 5010, and
5020 Tractors
On tractors equipped with a height stop lock, ad-
just by pulling upward on the stop lock and slide
to desired setting. Push stop lock down to lock
in posi- tion. On those tractors not equipped
with a height stop lock, use the height stop lock
provided with the plow. Position in rockshaft
control lever slot. ATTACHING PLOW TO
TRACTOR 3-Point Hitch 4020 Tractors Only
A height stop lock is provided with the plow when
used with this tractor. This stop consists of a
clipped head square neck bolt, washers, and a
wing nut. To attach the stop, insert the bolt
head into the rockshaft control lever slot and
turn bolt until square neck of bolt fits into
slot to prevent bolt from turning. Place washer,
lock washer, and wing nut on bolt. Set stop for
proper height and tighten wing nut. For ease in
attaching, remove one sway block from tractor
before attaching plow to tractor. Place rockshaft
selector lever in the D position. Adjust length
of lift links as needed to align draft lin k ends
with hitch crossbar.

pins and lock in place with hitch bar pins and
washers provided before raising plow.
Adjust length of lift links as neaded to align
lower coupler hooks with the hitch
crossbar. Raise the coupler with the tractor
rockshaft control lever. As the coupler receives
the weight of the plow, the implement hitch pin
adapters will be locked auto- matically in place
by the spring-loaded latches. Reset lift links as
shown on page 5. NOTE When I.be spring-loaded
latches are proper- ly locked, the indicator rod
will protrude t.trough ttie slot in the coupler
frame adjacent to the latch rods.
Close the telescoping draft links either by
raising and lowering the plow with the tractor
rockshaft con- trol lever or by backing up the
tractor.

NOTE The center link is not used. Quik-Coupler C
AUTION Do not hitch plow to tractor with
the tractor turned at an angle to the plow. Be
sure to lock Quik-Coupler latches before raising
plow to prevent plow from upsetting. 4020
Tractors
Place selector lever in the "D" position. Push
both Quik-Coupler latches downward and to the
rear to lock them in the released
position. Adjust length of lift links as needed
to align lower coupler hooks with the hitch
crossbar. Lower the hitch assembly until the
attaching hooks are lower than the plow hitch
pins. Back up the tractor until the plow hitch
pins enter the lower hooks. Raise the
Quik-Coupler to raise the prow. Pull forward and
upward on the latches to lock the plow to the
coupler. Reset lift links as shown on page
5. NOTE When the latches are properly locked,
the /n4icafor roc/s will protrude through the
slots in the coupler lrame adjacent fo the latch
rods.
When attaching Ouik-Coupler to tractor 3-point
hitch, make sure center link is set according to
the dimensions given in chart on page 5. Slide
adapters over the plow hitch pins. Drive spring
pins through adapters and hitch pins until they
are flush with the surface of the adapters. Place
the rockshaft Selector lever in the "D" posi-
tion. Make sure spring-loaded latches are in the
re- leased position. NOTE On 4020 Tractors below
serial no. 201, 000, Quik-Coupler Latch Lock Pins
are necessary when using a Quik-Coupler. If your

10 Opera tion
Checking Plow and Tractor
IMPORTANT Index the plow to be sure ram cylin-
der hoses do not draw taut as the plow cycles.
With plow attached to tractor and in raised
position, move support stand to storage position
as shown be- low.
CAUTION EGCaping hydraulic oil under pres- sure
can cause personal injury therefore, be
s
sure all connections are tight and that lines and
hoses are not damaged. DETACHING PLOW FROM
TRACTOR
CAUTION Before detaching, be sure to posi- tion
the support stand to support the plow after
t
it is disconnected from the tractor.
Remove the support stand from its down position
and insert pin on stand through hole in fourth
frame bar and secure with spring locking
pin. NOTE Top of support stand must straddle
bolt in frame bar to prevent stand from
pivoting. Raise the plow slowly and watch for any
interfer- ence. Be sure that the lift links are
set at the recommend- ed length shown on page
5. For most plowing conditions, set the
rockshaft selector lever in "LD" (middle)
position. In very light draft soil or in
irregular surface conditions, "L" posi- tion may
give better performance. CAUT I ON Alwayc lower
th e p!ow to the ground when not In use. The ram
cylinder hoses should have a loop of 2- 1/2
inches from the hose end to the hose clip as
shown below to provide enough slack when indexing
the plow.
Remove the support stand from its storage posi-
tion. Insert notch in top of stand under the bolt
head (with the washer and spacer) in the rear
support plate. Insert the pin through hole in the
support plate and secure with cotter pin. The
support stand can be attached to support the plow
with right- or left-hand bottoms down. Disconnect
all hoses from the breakaway couplers on the
tractor. Disconnect plow from tractor
hitch. CAUTION When detaching the plow from
a ,_at__at_, tractor equipped wtth a Quik-Coupler, be
sure to position p!ow and tractor in a "straight
ahead" pos- ition on level ground and lower the
plow within two inches of the ground before
releasing the coupler latches to guard against
plow tipping.

H ITCII ADJUSTMENTS
hitch as desired, line up hole in hitch pivot
shaft with noie in steering crank, and insert
lock bolt. Push clamp collar up against pivot
bracket and tighten col- lar bolt. After hitch
has been moved, adjust the turnbuckle to remove
end play from the draft rods. Tighten jam nut
securely against turnbuckle. IMPORTANT Do not
ovartighten the turnbuckle. Overtightening will
cause binding in hitch pivot as- sembly.
The plow can be hitched to the tractor by means
of the 3-point hitch or the Quik-Coupler.
Hydraulic Landing Hitch (Optional Equipment)
âRA!UL ltD
Horizontal Hitching Horizontal hitching is
accomplished by the tractor rear wheel spacing.
See page 3 for the proper wheel settings. The
hitch crossbar must be secured by inserting the
stop bolts through the inner holes in the hitch
crossbar as shown above. Vertical Hitching Three
holes in the hitch pivot shaft permit three
height settings. For average conditions, the
middle setting will give good performance and is
assembled at the factory in this position. If
necessary, to provide better tractor stability
when operating, lower the hitch pivot shaft one
hole. When plowing deep or hitch is gathering
trash, raise the hitch pivot shaft one hole. If
the plow hitch is moved, the draft rod lurnbuckle
must be adjusted. The draft rod turnbuckie must
be loose while moving the hitch. CAUTION When
removing lock bolt from steering crank to change
hitch location, be sure to block or hold hitch
assembly to prevent it from falling. To change
hitch location, loosen clamp collar and remove
lock bolt from steering crank. Raise or lower
The hydraulic landing hitch permits using wheel
settings of 32, 33, 34, 35, o/ 36 inches. The
stop bolts are used to control the width-of-cut
for the rear wheel setting used. When using a
35-inch rear wheel setting, place stop bolts in
second holes from the center of
the crossbar. When using a 34-inch rear wheel
setting, place stop bolts in third holes from the
center of the cross- bar as shown above. When
using a 33-inch rear wheel setting, place stop
bolts in outer holes in the crossbar. When using
a 32-inch rear wheel setting, the stop bolts are
not used.

12 Operation
RAISI NG AND LOWERING The plow is raised and
lowered by the tractor hy- draulic system.
Moving the rockshaft control lever rearward
raises the front of the plow, and moving the
operating lever (adjacent to the rocksnaft
control lever) rearward raises the rear of the
plow.
4020 (Below Serial No. 201,000), 5010, and 5020
Tractors
Moving the rockshaft control lever forward lowers
the front of the plow to its preset working depth.
Movinp the operating lever (adjacent to the rock-
shaft control lever) forward lowers the rear of
the plow to its preset workin9 depth against the
set screw depth stop DEPTH OF PLOWING The
rockshaft control lever on the tractor controls
the working depth of the plow. An adjustable stop
on the control lever quadrant is provided to
enable the operator to lower the plow to a preset
depth.
Mounted on the quadrant, this stop can easily be
bypassed with the lever if additional wor king
depth is desired.
Moving the rockshaft control lever forward raises
the front of the plow, and moving the operating
lever (adjacent to the rockshaft control lever)
forward rais- es the rear of the plow for turning
at the headlands, for crossing grass waterways,
and for transporting. Moving the rockshaft
control fever to the rear low- ers the front of
the plow to its preset working depth. Moving the
operating lever (adjacent to the rock- shaft
control lever) to the rear lowers the rear of
the plow to its preset working depth against the
set screw depth stop.
The Load-and-Depth Control of the tractor
hydraul- ic system tends to maintain the
operating depth over uneven ground or in varying
soil conditions, but al- ways keeps the working
depth within the limits of good piowing.
In some light draft soils or extremely rolling
land conditions, it may be desirable to set the
rockshaft sel ector iever in the L position.
NOTE. Be sure tractor hitch links are adjusted
properly, as shown on page 5. If improperly
adjusted, desired plowing depth may, not be
obtained.

ROTATING BOTTOMS The remote hydraulic cylinder
operating lever ac- tuated the two ram cylinders
on the plow which bring either the right- or
left-hand set of bottoms into work- ing position.
4020 (Serial No. 201,000 and Above) and 4520
Tractors
When the operating lever is moved one way, the
plow will rotate clockwise (right set of bottoms
down) . To rotate the bottoms counterclockwise,
move the lever the opposite direction. The lever
automatically returns to neutral when released
after the rotating cycle. CAUTION When indexing
plow be sure no one is in the plow indexing
path. NOTE Be sure to hold remo te cylinder
operating le- ver until plow is completely
indexed before lowering plow for placing. The
hydraulic indexing ram cylinder, steering
cylinder, and landing cylinder must be com-
pletely filled with oil to relief valve pressure
to insure good plow operation.
On tractors equipped with two breakaway cou-
plers, the outer remote cylinder operating lever
con- trol s the rotation of the plow.
4020 (Below Serial No. 201,000), 5010, and 5020
Tractors
On tractors equipped with three breakaway cou-
plets, the middle remote cylinder operating lever
con- trols the rotation of the plow. Pulling
the lever rearward rotates the bottoms
counterclockwise for left-hand plowing. Pushirig
the lever forward rotates the bottoms cloc kwise
for right- hand piowing. ADJUSTING ROLL-OVER
SPEED If it is necessary to adjust the roll-over
speed of these plows when used on a 4020, 4520,
5010, or 5020 Tractor, see your tractor
operator's manual for instructions on adjusting
rate of operation of the re- mote hydraulic
system.
The outer remote cylinder operating lever
controls the rotation of the plow. Pushing the
lever forward rotates the bottoms
counterclockwise for left-hand plowing. Pulling
the lever rearward rotates the bot- toms
clockwise for right-hand piowing.
