Safety Suggestions
CAUTION Improper use of the plow can result in
personal inury. Please read and understand all
safe operation rules before using the
plow. OPERATION For tractor stability and
operator safety, tractor front end weights and/or
liquid ballast in the front tires may be
required. See page 9. Do not attempt to adust
the plow while it is in motion. When detaching
the plow from the tractor, block or support the
plow frame to prevent the plow from tip-
ping. Never permit any person other than the
operator on the tractor. Never ride or permit
others to ride on the plow. Stand clear of plow
when raising and lowering. Do not allow children
to operate tractor and plow nor adults without
proper instruction. Keep children and pets a safe
distance away. Follow all safety precautions
stated in your tractor operator's manual. If
spray can paint is used, be careful when
discarding empty can. Do not incinerate or
puncture can.

TRANSPORTING Never travel at any speed which does
not permit adequate control of steering and
stopping. Reduce speed when traveling over rough
or uneven ground. Always use a trailer to
transport the tractor and plow long distances. Be
certain sway chains are adjusted to prevent
exces- sive side sway when transporting the plow.
Adiust length of chain with turnbuckle.

Description
GENERAL
The purpose of the moldboard plow is to turn and
break up the soil, admitting air, light, and
moisture and to cover surface vegetation
completely. Mixed with the soil, the decaying
plants provide food for the subse- quent
crop. The principle of the pulverizing effect of
the moldboard plow is shown in the illustration
at left. As the soil moves up the curved surface
of the mold- board, it is progressively sheared
and pulverized as illustrated by the pins 1, 2
and 3.
4-8

• IMPORTANCE OF THE BOTTOM
• No matter how well a plow may be built, proper
  care of the bottom is a must for good
  performance. If the bottom fails to scour and
  turn the soil properly, the seedbed will be
  uneven and lumpy, resulting in lower yields.
• Unnecessary delays at plowing time are often
  caused by a bottom that will not scour properly.
  The trouble is usually caused by improper
  adjustment of the plow, or from insufficient care
  of the bottom.
• Protect the face of the moldboard and share from
  rust whenever the plow is not in use (even
  overnight) by applying a light coating o1 oil or
  grease. When storing the plow for the season,
  apply a good rust preventive such as John Deere
  Plow Bottom Soft Black Paint. A well cared for
  plow bottom will help insure good scouring and
  better performance.
• Be sure the tractor and plow are adjusted
  properly. Before going to the field, check plow
  coulter and land- side settings initial settings
  are given under "Preparing the Plow on page 13.
  Check tractor hitch link lengths starting point
  settings are given on page 11. Make final
  adjustments in the field as described on pages
  23-25.

6 Description
Crowding - a characteristic of an improperly ad-
justed plow which causes the plow to pull to the
right or to the left. Draft - the pull or load
imposed upon a tractor by a plow or other similar
ground engaging tool. Draft Li r1kS - the two
lower hitch links of a tractor three-point hitch
which bear the pulling load.
4-8
Frog - the basic part of a plow bottom to which
the moldboard, landside and share are attached.
FMrrOW - the trench made by the movement of the
plow bottom in the ground. Furrow Wall - the
flat, vertical earthen surface on the left-hand
side of the trench left by the plow bottom.
Heel, Adjustable - the adjustable part on
the rear of the landside that gauges the depth of
the plow. Land Polish - the bright metallic
luster on a plow bottom from the scouring or
cleaning action of the soil.

Rockshaft - a shaft and connecting links coupled
to the tractor hydraulic system permitting
raising and lowering of mounted equipment. The
rockshaft is con- trolled by a control lever
located on the right-hand side of the tractor
seat. Scouring - allowing the soil to move across
the face of the moldboard without sticking. Share
- the portion of a plow bottom which contacts and
cuts the base of the furrow slice.
4-8
AShare Wing BShare Point S hear BOIt - the
5/16-inch bolt in the standard and plow frame
which allows the standard and bottom to pivot
rearward when striking an obstruction with
sufficient impact force to shear the bolt.
i
Shin - the replaceable front part of the plow
bottom that severs the furrow slice
edge. Standard - the vertical support to which
the plow bottom is mounted. Suck - the ability of
a plow bottom to penetrate the ground. Sway
Chains - the turnbuckle and chain links attached
to the draft links and tractor axle which are
used to keep the draft links away from the
tractor tires. TFash - the surface vegetation
remaining from pre- vious crops. The plow coulter
must slice cleanly through trash to give a smooth
furrow wall.

PREPARING THE TRACTOR General For complete
tractor operating instructions, refer to your
tractor opeator's manual. Tire Inflation Inflate
the tractor tires as recommended in the tractor
operator's manual.
Rear Wheel Weighting Rear wheel weights are
necessary to eliminate exces- sive wheel slippage
or for stability in rough or hillside fields.
However, weights should not be added to the point
where all slippage is eliminated. This hinders
maximum performance of the tractor. The ideal
amount of added weight can be determined by
observing the tracks of the rear wheels. When the
tractor is pulling its rated load, the soil
between the tire lugs should be broken or
shifted. If too much weight has been added, the
tead marks wifl be cear and distinct. If too
little weight has been added, the tread marks
will be entirely obliterated. Liquid
Weights Water and calcium chloride solution is an
economical means of adding weight to rear wheels.
Calcium chlo- ride 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 the
rear wheels. This type of weight can be purchased
from your John Deere dealer. Cast-iron weights,
liquid weight solution, or a combi- nation of
cast-iron and liquid weight are required to
obtain proper rear ballast. For maximum ballast,
refer to your tractor operator's manual.

10 Preparing For Use
Front End Ballast Information Tractor front end
stability is necessary for safe and efficient
operation. Therefore, it is important that the
proper amount of weight be installed on the front
of the tractor as recommended in your tractor
operator's manual. Find which plow model you have
in the IMPLEMENT CODE TABLE. With the proper code
number, refer to your tractor operator's manual.
It will give the required weight to use for your
plow. IMPLEMENT CODE

CAUTION Always use front end weights when
operating the plow to prevent the front end of
the tractor from raising off the ground. Drive
slowly when traveling over rough or uneven
ground and hillsides.

Three-Point Hitch Link Lengths The center link
attaches to the mast on the plow and controls
plowing depth. It is important that it be
properly set. It should be attached to the
tractor using the second set of holes from the
bottom. The lift links adjust the plow from
side-to-side. The right-hand lift link is
adjustable. The left-hand lift link should be
attached to the left-hand draft link in the
bottom set of holes (C" in the illustration at
right). Measure the center link and the
right-hand lift link from center-to-center of the
attaching pins. See illustration at right and
chart below for dimensions.
