operation
Preparing the tractor
The tractor must be equipped with an 8- inch
stroke remote hydraulic cylinder that con- forms
to ASAE-SAE standards.
If possible, set the tractor rear wheels 72
inches, center to center of tread and equal
distance from center line of tractor. The planter
ground wheels will then run in the center of the
tracks left by the rear wheels of the tractor. If
this cannot be done it is best to adjust the
tractor rear wheels so the planter wheels run
entirely out of the tractor wheel tracks.
On tractors with an adjustable drawbar,
place the drawbar approximately 15 inches
from the ground and bolt it in the center of
the tractor.
Preparing the planter
Lubrication Consult the lubrication charts on
pages 56, 57, and 58 for guidance in
lubricating your planter.
The special 495A planter with the narrow wheel
frame can be set to drill or hill-drop in 28-,
30-, 32-, 34-, 36-, 38-, or 40-inch row widths.
Regular and systematic lubrication is the best
assurance against breakdowns and delays. It
will help you get better service from your corn
planter and save on your maintenance costs.
The 494A hill-drop planter, with check-row
attachment, can be set to check-row in 36-,
38-, or 40-inch row widths.
Tire inflation Irdlate the planter 6.70 z 15
traction-type Urea to 24 ps1 o/ air pressure.
The planters are assembled for 40- inch row
widths, as illustrated on page 5. To change the
row widths proceed as follows
Lower the planter until the runners rest on the
floor. Remove the bolts holding the sill bar
brackets to the main frame,
Gear ease Remove the oil plug and check oil level
in the gear case. If necessary, fill gear case
with SAE 20 engine oil.
Remove the cotter pins holding the pressure
spring rods to the main frame.
Row widths The regular 494A or 4 95A Planter can
be set to drill or hill-drop in 30 -, 32-, 34-,
86, 38-, or 40-inch row widths. For 30-inch row
widths, smaller diameter seed hoppers must be
used,
On the 494A planter only, loosen the bolts in the
valve rod trip arms.
Move the planting units , the valve rod trip arms
(494A only), and the spring rods to the desired
row widths.
On the 494A hill- drop planter for row widths of
34 inches or less, remove the reel of wire and
reel brackets if planter is so equipped.
Bolt the sill bar brackets to the main frame and
replace the cotter pins in the pressure spring
rods.
The Special 494A hill-drop or drill planter with
the narrow wheel frame can be set to hill- drop
or drill in 28-, 30-, 32 -, 34 -, 36 -, 38- or
40-inch row widths.
On the 494A planter only, tighten the valve rod
trip arm bolts, and check the valve adjust- ments
as explained on pages 66 and 67.

Marker adjustment The regular markers on the
planter are ad- justable for 34-, 36-, 38-, or
40-inch row widths. For 28-, 30-, or 32-inch
row widths it is necessary to equip the
planter with special markers. The marker
illustrated is set for 36-inch row widths. To
change the markers for other row widths loosen
the set screws so marker pipes will slide.
Setthe inside end of each marker pipe to line up
with the center of the hole in the marker arm,
for approximate row width. Turn each marker pipe
so bracket "A" is in position
illustrated. Tighten
the set screws securely to
hold
markers in position. The angle of each
marker disk may be adjusted for various
soil conditions by loosening bolt "B" and
turning the disk. After adjustment is made
tighten bolt "B" securely.

6 operation
The planting speed is very important in deter-
mining which seed plate to use. The planting
rate is determined by the cell fill of the seed
plate. The faster the planter is operated the
faster the seed plate revolves. Therefore at
faster planting speeds it may be necessary to
use seed plates with slightly longer cell length
to obtain the proper cell fill for the planting
rate that is desired.
Seed plates
The selection of the seed plates is one of the
most important steps in pr eparing the planter
for the field.
There is a great variety of John Deere seed
plates available in various cell sizes and number
of cells.
Growing conditions change from year to year, and
the size of the seed will also vary. There- fore,
it is quite likely that different seed plates are
required to plant the same variety of seed from
year to year.
A 24-cell seed plate revolves at a slower rpm
than a 16- cell seed plate, the result being
better cell lill at the same planting speed. It
is therefore recommended that a24-cell seed plate
be used in all cases when available for hill-drop
or drill planting.
There are two ways to select seed plates. One wa7
is to follow the recommendations or the seed
supplier, if available. The other way is to take
a sample of the seed to be planted to a John
Deere dealer and let him run the seed through
his John Deere seed plate se Ieetor stand.
NOTE Due to the fact that a 24- cell seed plate
resolves at a Slower km than a 16-cell seed
plate, a 24-cell seed plate will plant at a
heaz'ie z rate than a 16-cell need plate wtfii
the same cell size at a given dri fling or
trill-drop - ping distance and planting speed.
The becom- mended planting speeds on pages 14,
16 and 19 tabe this tnio conside u you both
16- and 24- cell plates.
In e ither case the accuracy of the seed plate
selected shouia be checked when installed in your
planter and operated at the planting speed you
intend to travel. The best check is to plant a
short distance, at the desired planting speed,
and then stop and dig up the hills of corn to
determine the actual planting rate.

corn plates available with 16 and 24 cells.

fertilizer drive, under the support pipes and
through the chain guides. Attach the mariner
control chains to the springs and chain arm.
Attach the chain arm (and wire guide for
checkrow planter) at right angles to the tractor
drawbar. Tighten the bolt securely as the marker
chain arm must be held rigidly to the tractor
drawbar.
Retract the hydraulic cylinder until the plant-
er hitch is the same height as the tractor draw-
bar. Attach the clevis to the tractor drawbar
with the clevis pin and secure in place with the
retaining pin as shown. Extend the hydraulic
cy1inder to raise the planter off of the stand.
Set the clevis in hoies "A," "B," or 'C, ' so the

accessory lights and devices for adequate warning
to operators of other ve- hicles. In this regard,
check local governmental regulations. Various
safety lights and devices are available from your
John Deere dealer.
The marker control arm will stay in this po-
sition, and the right-hand marker will raise and
drop when planter is raised and lowered until the

Set the shift lever on 2 or 4. Lower the plant-
er and pull the ptante r forward until the square
drill shaft stops turning and is in the position
shown. Attach the double striker to the drill
shaft, in a vertical position, so the rolle rs

Hilling distances and planting apeed
TH
ET Position the chain idler so there is 3/4-inch
slack in drive chain,
The hilling distance will determine the max- imum
recommended speed when planter is used for
hill-drop planting.
LEVE
For hill-drop planting, the shift lever and
the sprocket setting varies the distance be-
tween the hills.
The chart on the following page gives the
approximate hilling distances which are obtain-
able and the maximum recommended speed.
The number of cells in the seed plate and the
single or double striker regulate the number
of kernels per hill.
After planting about 80 rods, make a seed
population check at selected operating speed.
At speeds over 5 mph some seed grades may re-
quire a seed plate with slightly longer cells for
better cell fill.
