PREPARING THE TRACTOR
The tractor must be equipped with an 8-inch
stroke remote hydraulic cylinder that conforms to
ASAE- SAE standards. On tractors with an
adjustable drawbar, place the drawbar
approximately 15 inches from the ground and bolt
it in the center of the tractor. I f possible,
set the tractor rear wheels, center-to- center of
tread an equal distance from center line of
tractor, as follows
Row Width Tractor Rear Wheel Tread
30 Inches 60 Inches
38 Inches 76 Inches
40 Inches 80 Inches
If the tractor rear wheels cannot be set
according to the chart, adjust them so the
planter wheels run entirely out of the tractor
wheel tracks.
PREPARING THE PLANTER Markers
Lubrication
Consult the lubr ication charts on pages 34, 35,
and 36 for guidance in lubricating your
planter. Regular and systematic lubrication is
the best as- surance against breakdowns and
delays. I t will help you get better service from
your corn planter and save on your maintenance
costs Tire Inflation Inflate 7.50-18
traction-type tires to 24 psi of air pressure and
5.70/5.00-8 to 55 psi of air pressure.
The markers on the planter are adjustable for
30-, 38-, or 40-inch row widths. The marker
illustrated is actually set for either 30- or
40-inch row widths. To change the markers for
other row widths, loosen the two set screws in
each marker so the marker pipes will slide, The
distance bet veen the bottom edge of the disk and
the pivot pin determines the marker setting.
For 40-inch row widths the distance must be
approximately 27-1/4 inches, for 38-inch row
widths the distance must be approximately 15-1/4
inches, and for eight 30-inch rows the distance
must be approximately 27-1/4 inches. Turn each
marker pipe so bracket A" is in position as
illustrated. Tighten set screws securely to hold
markers in place.

Opera tion 5
Select the desired row spacing and position the
units as follows Place each inside unit one-half
the distance of the desired row width from the
center of the planter frame to the center of the
sill bar bracket. Center remaining units at
desired row widths. Tighten all sill bar bracket
bolts. Attach pressure rods to planter frame in
appropri- ate holes.
Changing Row Widths The 1 260 Planter is
available in 38- and 40-inch row widths. The 1280
is available only in 30-inch row widths. To
change the row widths, proceed as follows Lower

Various drawbar heights may be obtained by using
the hitch xtension in different combinations
with the drawbar. The hitch extension may be used
as shown, turned over, under the drawbar in
position shown, turned over under the drawbar, or
any of the above combina- tions with the tractor
drawbar turned over. Install the remote hydraulic
cylinder. Place the hydraulic hoses in the hose
holder. With the cyl inder retracted, remove pin
B and place in hole C. Extend the remote
hydraulic cylinder and set stop A so the
cylinder will retract all the way. This will
permit the planter press wheel to always gauge
the planting depth.

Pull the chain tight enough to hold the markers
snug against marker assist lever. Slide chain
into slot and replace dr illed pin "A" and hold
in place with cotter pin. MARKERS The position
of the marker control will determine which marker
will drop when the planter is lowered. CAUTION
Fold the markers over onto the marker support
when moving the planter.
NOTE When markers are held up, chains will be
slack. When raising planter, be very careful tha
I slack chain does not catch and break.
With the remote hydraulic cylinder extended,
place the pin as illustrated.
Bolt the marker control chain arm to the tractor
drawbar or hitch extensions. Tighten the bolt
securely as marker control chain must be held
rigidly to the tractor drawbar.
When the marker control points to the right-hand
side of the planter, as illustrated, the
right-hand marker will drop. The marker control
will stay in this position, and the right-hand
marker will raise and drop when planter is raised
and lowered until the tractor is turned sharply
to the left. Then the left-hand marker control
chain will tighten and point the marker control
toward the left-hand side of the planter and the
left-hand marker will drop when planter is
lowered. The marker that is down will
automatically raise when the planter is raised.

II necessary, level units with sleeve adjusting
nuts on adjustable lower shan k drawbar. Tighten
locking nuts to 150 ft-Ibs torque.
If the right-hand marker will not drop after a
sharp turn, shorten the right-hand marker control
chain at spring, one link at a time, until
right-hand marker will drop after a sharp left
turn. Shorten the left-hand marker control chain
if left-hand marker tails to drop after a sharp
right turn.
Each planting unit has a spring which can be ad-
justed to vary the down pressure on the planting
unit. If the runner tends to ride out of the
ground, raise the planter and move the adjusting
bracket down to the next position. NOTE Do not
attempt to penetrate the plow pan. In hard soil
conditions, this could cause the planter drive
wheels to raise otf the ground. Adjust all
planting units so the spring pressure is the same
on each unit. NOTE When operating in the tield,
lower ihe plant- er only when the tractor is
moving forward. This will prevent the planter
runners trom clogging in moist soil conditions.
PLATELESS PLANTING UNITS - DRILL ONLY
Planting Depth Planting depth is gauged by the
planter press wheel and not by the tractor remote
hydraulic cylinder. The remote hydraulic
cylinder must be fully retracted when
planting. NOTE When using double-disk furrowers,
furrow- ers gauge depth of seed planter press
wheel gauges depth ot furrow.
In some field conditions where planter trame must
be closer to ground than normal, and when there
is no additional adjustment to pressure rod,
position lift arm in hole A in wheel frame
Planting depth of each unit is determined by the
setting of the depth adjusting cam. To decrease
planting depth, pull out on the adjusting stop
and ro- tate depth adjusting cam clockwise. To
increase planting depth, pull out on adjusting
stop and rotate depth adjusting cam
counterclockwise. Each hole represents a change
of approximately 3/8 inch in planting depth.
Adjust all units to plant at the same depth.

Inspection and Cleanout
If seed hoppers are not empty, be certain to turn
the selector gates to the OFF position or seed
will escape from hopper through cleanout
hole. Remove INSPECT ION PLUG and check
fingers periodically. See SERVI CE section, page
37. For best operation remove CLEANOUT PLATE and
clean out finger pickup housing after each day's
use.
To plant corn with the finger pickup section of
the planter, move the selector gate from the OFF
position in a clockwise direction until it locks
in place in the position marked CORN.
Selector Gate The selector gate has three
positions marked as follows OFF, BEANS SORG
HUM, and CORN.
To plant soybeans, maize, or other small grain
with the precision feed cup section of the
planter, move the selector gate from OFF position
in a counter- clockwise direction until it locks
in place in the posi- tion marked BEANS SORG HU
M. For instructions on using pecision feed cup,
see page 16.
Before removing the hopper, turn the selector
gate to the OFF position to close the opening in
the hopper bottom. NOTE Be sure to turn selector
gate io OFF posi- tion for transporting.
