OP ER ATIO N IkIPORTANCE OF PROPER ADJUSTklENT
Your new plow is fully adjustable and, when
properly adjusted to oper- ate in the type of
soil and field con- ditions on your farm, it will
do a good job of plOwing at a minimtlfn of
expense. A well-adjusted plow pulls lighter
its furrow slices are
uniform in width and depth it cover e trash
it leaves the soil in proper condition to be
worked down into the best-type seedbed. Improper
adjustment results in rapid wear and possible
breakage of partG, and inefficient operation.
PREPARING THE PLOW BOLTS AND SET SCREWS
PLOW DISKS
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 eotter
pinfi spread to keep them from fall- ing out.
Check the bolts that hold the plow disks to see
that they are drawn up very tight.
The polished surfaces of the plow disks and
scrapers 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 contact With the soil. In those
soils where the blaclr paint yill not clear off,
remove with gasoline, kerosene, or diesel
fuel. Be earef u1 when uaing any of t hese fuels
so they do not ignite. Plow should be in a
well-ventil ated area and away from any sparks or
flames. lf the plow is not to be used im-
mediately, protect the polished eur- faces by
applying a coat of cup or gun grease. If plot is
to be put in storage for a considerable length of
time, see page 17.
A good practice is to check for loose bolts,
screws, or parts when lubricating the plow.
Loose bolts are easily lost or cauee excessive
weas on parts, resulting in possible serious
damage to the plow.
LUBRICATION Be sure plow has been properly
lubricated. See Lubrication Chart on page 18.

REA R WH EE L GWE I HT I NG In average coDd1 tO
D s, rear wheel weights are not necessary. In
those conditions where it becomes neces- sary to
add weight to the rear wheels, see your tractor
Operator's Manual for weighting
instructions. Power can be lost and tire life cut
drastically by wheel slippage. Add- ing
weight also serves to stabilize the tractor when
plowing in rough or hillside fields.
For complete tractor operating in structions,
refer to your tractor Op e
"
ator's M anual. Tl RE INFLAT ION
Inflate the tractor tires as recom- mended in
the tractor Operator's Manual. For plowing, add
4 pounds more air in right rear tire than in left
rear tire. Proper air pressure is the most
important factor in satisfactory per- formance
and maintenance of trac- tor and implement
tires. Underin- flation will damage the cord
body of the tire and cause a series of radial
breaks in the sidewall fabric. This may
occur on the inner sid.wall of the furrow
wheel tire. If the tire buckles or wrinkles,
the air pressure should be increased to where
the sidewalls remain smooth while oper-
ating. If additional traction is required, add
weight to the wheels. Reducing the recommended
air pressure will make little difference in the
traction and may ruin the tires.
TRACTOR DRAWBAR Set the tractor drawbar in
the short high position and remove pins or
bolts so drawbar is free to swing. REAR WHF.EL
5ETT ING On tractors with adjustable rear
wheels, the rear wheels must be set in the
narrowest tread to obtain the most efficient
operation of the plow and tractor. FRONT WHEEL
SETTINGS On wide-front-end tractors, set front
wheels to conform to rear wheel setting,
center-to-center of tread.
Check air pressures every two or three weeks. Use
a special low pres- sure gauge having l-pound
gradua- tions.

on
Be sure the tractor rear wheels are set in their
narrowest position. Meas- ure the distance from
the center of the tractor drawbar to the inside
of the tractor tire. Then set the plow hitch so
it is the same distance in from the plow furrow
wheel as the tractor draw bar is from the inside
of the tractor tire. Measure from the center of
the hitch to the inside of the plow furrow wheel
flange at the bottom, para11e1 to the ground. See
illustration above. To make this hitch
adjustment, move the hitch plate left or right
on the hitch cross- bar. Ground conditions may
require some change in the starting setting to
correct the width of cut on the front disk.
Keep the plow hitch run- ning as near straight
and parallel to the line of travel as possible
and still obtain the correct width of cut on the
front disk.
hitch adjustments are made by mov- ing the hitch
plate left or right on the hitch crossbar. Moving
the hitch plate toward the outer end of the hitch
crossbar de- creases the cut of the front
disk. Moving the plate toward the plow frame
increases the cut. Adjust the hitch plate on the
hitch crossbar so the front disk cuts the proper
width (from 8 to 10 inches). The front disk
should never cut more than the other disks. When
changing the position of the hitch plate, it is
u9ually necessary to adjust the furrow axle
steering bar to keep the front furrow wheel
running properly. The front furrow wheel
should run parallel with the line of travel or
with a slight lead toward the plowed ground in
heavy soil con- ditions. A series of holes in the
steer- ing bar allow the bar to be moved in or
out.
ADJUSTING HITCH Adjustrrients built into the
hitch are of the greatest importance. A wide
range of hitch adjustments are provided to adapt
the plow to vari- ous soil conditions, depths of
plow- ing, and to all types of tractors.

bolt the hitch plate to the hitch crossbar to
conform to this measurement. Vertical Hitch
Adjustments Two set of holes in the hitch plate
allow the plate to be moved up or down to obtain
proper vertical hitch adjustment. For average
to shallow ploWing, set the hitch plate in the
top holes. For deep plowing, set the hitch plate
in the bottom holes. These settings apply to
tractors with the drawbar set at average standard
heights (If inches from the ground).

On the 400H Series Ploys, the re- mote hydraulic
cylinder raises and lowers the p1o\v and
controls the depth of plowing. The 400H Series
plows can be equipped for hydraulic operation
with John Deere PoWr-Trol or the hydraulic system
of any tractor hav- ing sufficient capacity and
utilizing a remote cylind er that conforms to
ASAE-SAE standards. Your John Deere Remote
Cylinder is equipped with an adjustable piston
stop, so the working stroke may be adjusted to
control the working depth of the plow. The
stroke may be varied from 8-inch maximum to
0-inch minimum. For complete op- erating and
adjusting instruc- tions for remote cylinder,
refer to your tractor Ope ators Mact- uaI. When
transporting, raise the plow to highest position
by use of the re- mote hydraulic cylinder and
insert hold-up pin in transport position as shown
above. ATTACHING HOSES AND INSTALLI NG C YLI
NDER Before attaching hoses to tractor, relieve
pressure in the tractor hy- draulic system. To
relieve pressure, stop tractor engine and move
remote cylinder control lever back and forth
several times.
Wipe hose ends to remove any dirt before
inserting in break- away couplings. All
trapped air in the cylinder must be removed
after hoses are connected to breakaway
couplings. To remove trapped air, first place
cylinder on tractor transport arm with hose
end up. With engine stop- ped, engage pump. Then
start engine and operate the remote cylinder con-
trol lever back and forth seven or eight
times. With hold-up pin in transport po- sition,
install cylinder on plow. Ex- tend cylinder as
far as possible. Then move hold-up pin to
operating po- sition. Attach hose to hose
support, using S-hook and clamps provided. Adjust
the set screw collar on the hose support so the
rod will not in- terfere with either the plow or
trac- tor when turning. REMOVI NG CYLINDER Place
the plow in the lifted or transport
position. Remove hold-up pin from operating
position and place in transport position.
Releaee load on the cylinder and remove spring
locking pins. The plow will be held in the
lifted position and can be transported
without replacing the cylinder.

REAR TRUC K AD JUSTI NG BOLT
Adjustment is provided in the plow so that
the disks can be set to cut a furrow slice from
approximately 8 to 10 inches each. To increase or
decrease the width of cut per disk, loosen all
five bolts attaching the rear truck to the frame
and adjust as follows To increase the width of
cut, loosen the inside nut on the adjusting bolt
and tighten the outside nut. To de- crease the
width of cut loosen the outside nut and tighten
the inside nut. When the desired adjustment is
obtained, tighten all nuts securely. or best
resuIts in extrem ely trashy conditions set
plow to cut maximum width per disk. The in-
dividual disk will turn faster and shed
trash quicker at this setting. For penetration
in hard ground, set the plow to a narrower cut
per disk.
The 400 Series Disk Plows are raised and
lowered by the enclosed clutch. A rope attached
to the clutch trip lever controls the enclosed
clutch. To lift the disks out of the ground for
turning at the end of a row or for transporting,
simply give the trip rope a quick positive
pull. To lower the plow, pull the rope in the
same manner. NOTE Do vol tee a slow steady
pull since i/ riff cavse the clvlch to comtins
e tripping. The enclosed clutch on these plows F
provides constant lift so plow Will raise
completely to give full trans port and trash
clearance regardless of depth setting. Be sure
the clutch is properly lu- bricated at all times.

Depth can be set from approxi- mately 4 to 11
inches. There will be some variation in these
figures de- pending on size of disks. The depth
of plowing on the 400H Series Plows is controlled
by the re- mote hydraulic cylinder. On the 400
Series Plows, it is controlled by the depth
adjusting screw crank. LEVELING A leveling
screw crank is provided on both 400 and 400H
Series Plows to obtain a uniform depth of plowing
with each disk. After desired depth of plowing is
obtained with the rear disk, adjust the leveling
screw crank to regulate depth of the front disk
in relation to the rear. Once the 400H Series
Plow is
leveled, the plowing depth may be changed
without affecting leveling. On the 400 Series
Plow, the plow must be leveled whenever depth of
plowing is changed. LIFTING SPRING The lift
spring, located at the front of the frame should
be carefully ad- justed so that the spring will
assist the plow when lifting. To increase or
decrease sprin g te nsi on, turn spring bolt.
If the tension on the spring is too little,
the land wheel on the 400 Series may slide, due
to lack of traction, as the plow is lifted by the
clutch. If the tension is too great the plow
will penetrate too slowly when dropped to its
work.

REAR FURROW AXLE AND WHEEL The rear furrow axle
is adjusta ble laterally so that the rear
furrow wheel may be set toward or away from the
furrow wall. To adjust the rear furrow
axle, loosen the set screws in collars and move
the axle in or out. For un- usually tough
conditions, which may cause the land wheel to run
toward the plowed land excessively, move the
rear wheel and axle to the furrow wall. for
lighter soil conditions, which may cause the
land wheel to run toward the unplowed land, move
the rear wheel out or away from the furrow
wall. When the rear furrow axle and wheel
are adjusted properip the land wheel will run
straight with the line of travel. Operate
wheel-type tractors with right rear wheel in
the furrow. WHEEL SETTINGS For normal or hard
ground con- ditions, assemble the front and rear
furrow wheels as shown in the illus- tration at
top of next column.

on the land wheel or land axle. If the plow is
properly hitched to the tractor and the rear
furrow wheel is set in proper relation to the
rear disk or to the
furrow wall for the type of soil being plowed,
the land wheel will run ap- proximately straight
with the line of travel.
