OPERATION WE ED CONTROL AND CULTIVATION
Weed control is a necessary and important part of
farming. Profit stealing weeds rob farm- ers of
millions of dollars every year. It is es-
timated that the productlveness of the average
farm is reduced 25 percent annually because of
weeds.
PRO PER TIME FOR WEED E RADICATION
The proper time to make war on weeds de- pends a
great deal on field and weather condi- tions. It
is conceded by the majority of farmers and
agricultural experts that weed eradication can be
brought about successfully in the spring- time
before planting, aiso in the fall after the
harvest.
Weeds are a constant menace. It doesn't pay to
fight them In a half-hearted way. Flghting weeds
succ essfully calls for the most effective
Implements and methods. For this reason, the
farmer should study his field problems carefully
before deciding the size and type of cultivator
equipment best suited for his needs. Cutting the
weeds into pieces and burying them as often
happens when the wrong equipment is used, is
simply encouraging new growth of weeds.
In Spring or Before Planting If weed control is
practiced in the spr1rtgt1me or before planting,
the following simple instruc- tions should be
followed
1. Don't attempt to work more acreage than you
can handle thoroughly during thls period. Work
the field both ways at intervals until
planting time.
If any weed on your farm cannot be identified,
send to your agrlcultural college for a weed bul-
letin, or better, send a sample of the weed-stem,
flower, and root, when possible, and find out
what it is. Remember, weeds will spread and
the patches get bigger every year. It is much
easier to kill a small patch than a big one.
2. Don't remove the roots from the field un- less
they are so thick that they interfere wlth good
work. Remember that the decayed roots will form
humus and add valuable fertility to the soil. Be
sure that the roots are exposed to the air long
enough so that they die.
Weeds of all kinds, regardless oJ name, are in
two distinct classifications. They are desig-
nated as shallow-rooted or 'deep-rooted
weeds. Different weeds require different methods
of eradication. Shallow-rooted weeds, such as
Tuack grass, Johnson grass, Bermuda grass, and
the like, must be ripped out by the roots and
brought to the surface. Deep-rooted weeds such as
Canada thistles, Russian thistles, bindweed or
Creeping Jennie, Hoary Alyssum and the like can
only be destroyed by cutting off the stalks below
the surface.
3. Following above treatment, plant a row crop,
that can be cultivated, or a smother crop.
4. After harvesting this crop, work the field at
least three timeslengthwise, crosswise, and
diagonally before the freeze-up. Leave the roots
on top through the winter. In Fall or After
Harvest If weed control is practiced in the Call
or after the harvest, the following simple
Instructions will serve as a guide.
1. Don't attempt to work more acreage than you
can handle thoroughly during this period. Work
the field at least three timeslengthwise,
crosswise, and diagonally, before the freeze-up.
You can get good results in weed eradication with
the John Deere C-21 Field Cultivator. At the
same time you are killing weeds, you are also
stirring and mixing the soil and making a fine,
deep seedbed. There are styles of shovel
equipment suited for every Job.

1. Do not plow roots underleave them on the surface
   to dry and freeze as the decayed roots will form
   humus and add fertility to the soil.
2. The following spring, work the field both ways at
   intervals until planting time.

IONContinued DESTROYING SHALLOW-ROOTED WEEDS E
quip cultlvator with narrow shovels to up- root
shallow-rooted weeds. Weeds illustrated here and
weeds of a simUar character must be ripped and
dug out. Use spring teeth spaced 6 Inches apart
with double-pointed reversible 1-3/4-inch width
shovels (N506M). The vibrant motion of the
spring teeth separates the roots from the soil
and brings them to the top. The weeds should be
left exposed on the sur- face long enough to k111
the roots and then used as a fertilizer. In some
localities, it is necessary to rake the weeds and
burn them. Do not set the shovels too deep the
first time over, especially if the ground is
hard, as it might result in lumpy work. Here are
simple rules to follow when using spring-tooth
equipment. Set the shovels at a depth of about
2 inches the first time over. Then
cross-cultivate the second time over with the
teeth set to penetrate a maximum depth. IN the
field is thickly infested wlth roots, the ground
should be gone over a thlrd time, driving the
cultivator diagonally across the field. Tljjs
work can be done either in the spring or fall,
depending upon conditions.

RENOVATING PASTURE LANDS AND ALFAL FA FIELDS
ROUGHING STUBBLE LAND AND LIGHT SOIL TO PREVENT
BLOWING AND DRIFTING
Spring teeth with 6- or 9-inch spacing are used
extensively for this class of work.
Spring teeth with the special 1-1/2- inchwidth
double-pointed shovels AN130431 are recom-
mended for alfalfa cultivation. The double-point-
ed reversible shovel (N506M) can also be used.
In extremely hard ground conditions the
double-pointed reversible shovel (N506M) should
be used for the first cultivation.
Depth of cultivation depends on the age of the
crop, the variety of alfalfa, and the condition
of the soil. Branch root varieties should not be
cul- tivated deeper than 3 inches when the crop
is young-established stands may be cultivated as
deep as 4 inches. Taproot varieties can be cul-
tivated to a depth of 6 inches. When the soil is
hard, the first and second cultivations should
always be shallow in order to breakup the clods,
and to prevent the plants being pulley up with
the clod. In loose r soils, first and second
cultiva- tions may be deeper except In wet soils
where the alfalfa is of the branch root variety.
In all conditions. it is the best practice to
cultivate shallow the first two tlmes, following
with deeper cultivations to a depth best suited
for your crop and soil conditions. Cultivating
can be done either in the spring or Call,
depending on conditions.
MAKING SEEDBEDS AND GENERAL TILLAGE
Spring teeth with the double -pointed reve rs-
ible 1-3/4-inch width shovels (N506M) are rec-
ommended for this class of work. 4-1/2-inch
shovels (N674MN) or 10-inch shovels (N850MN) are
also used under certain field conditions.
Seedbeds can be made to a depth of about 8
inches.
SUMMER- FALLOWING
Either 6- or 9- inch spaced spring teeth with
wide overlapping shovels, can be used for sum-
mer-Wallowing.
The depth of penetration required depends upon
the conditions of the soil. It is important to
keep shovels sharp.

d DESTROYING DEEP- ROOTED WEEDS
Equip cultivator with wide shovels to erodl-
cote deep-rooted weeds. Weeds illustrated here
and weeds of a similar character must be
destroyed by cutting the root- stalks below the
surface. Wide shovels that over- lap must be
used. The deep rooted weeds must be continuously
cut off. Cutting at frequent inter- vals weakens
the plants and eventually kills the roots. Do not
put the shovels down too deep the first time over
the field. A depth of about 3 to 4 inches is
recommended for the first time over. Then cross
the field a second time and set the s hov e1s to
penetrate the maximum depth. The second treatment
invariably cuts off every root. 11 the field is
thickly Infested with the roots, the ground
should be gone over the third time, driving the
cultivator diagonally across the te1d. It is
important to keep shovels sharp for this type of
work.

7.60 - 15, 8-p1y tires - 48 psi
DE PTH CONTROL RIGID CULTIVATORS
Depth of penetration of spring teeth is con-
trolled by the location of the adjustable depth
stop on the main lift cylinder. The cylinder is
retracted in the operating position and extended
in the raised position. When operating, the depth
stop should be against the stop rod on the cylin-
der. To increase the depth of penetration, move
the depth stop toward the shoulder of the yoke.
To decrease the depth of penetration, move the
depth stop toward the stop rod on the
cylinder. When positioning the depth stop, make
sure it lines up with the stop rod on the
cylinder. The main lift cylinder controls the
depth of penetra- tion of all spring teeth.
A remote cylinder is used to ralse the culti-
vator for transport and lower it for operation.
Depth of operation is controlled by the location
of the adjustable depth stop on the cylinder. 5ee
your tractor operator's manual. The cylinder
is retracted in the operating position and
extend- ed in the transport position. When
operating the cultivator, the adjustable depth
stop should be against the stop rod arm on the
cylinder.
IMPORTANT Refer to your tractor opera- tor's
manual and check hydraulic oil supply after all
depth control cylinders have been filled with
oil. Add the recommended oil to the hydraulic
system as outlined in the tractor operator's
manual. The remote cylinder operating lever on
the tractor controls the depth control system.
Install hoses in such a manner so when pushing
the lever forward the spring teeth will raise
and pulling the lever back the spriflg
teeth will lower.
A pin secures the cylinder attaching block to
the rockshaft arms. For ease in attaching
cylinder, remove pin to allow the block to move
forward.
If the cylinder is removed for use on other
implements, place the pin through hole A' ' be-
fore removing the cylinder. This will keep the
spring teeth off the surface.
