4. Disengage the fertilizer drive sprocket by pulling
the plunger pin and turning it to be parallel with
the drive shaft.
5. Raise the drill to the transport position and install
pins in the transport locks.
Refer to Figure 7
6. Place the crank handle on the right-hand contact
drive shaft and turn the crank several times to fill
seed meters. Turn crank until seed drops from
each seed meter. Slide seed calibration tray to
the right until it reaches the stop. Tilt tray down
and use brush or rag to remove seed. Place tray
back under meter and secure in place.
7. Turn crank on contact-wheel shaft counter clock-
wise 32 revolutions for 1/100 hectare seeding
rate. While turning, check that the seed meters
have plenty of seed coming into them. (For a
more accurate calibration it is recommended to
lower drill to planting position. Drive forward a
short distance so meters fill with seed. Empty
calibration tray into a container. Place tray back
under meter and secure in place. Drive forward a
measured distance of 33.3 meters.)
8. Weigh metered seed, subtracting container
weight. Multiply weight by 100 to determine total
kilograms by hectare seeded. If this figure is dif-
ferent than desired, adjust seed-rate handle ac-
cordingly.
9. When through with calibration, use the crank
handle to rotate the calibration shaft index collar
to the left.
NOTE: Decals located next to calibration shaft index
collars indicate proper rotation for calibration and
field operation.
10. Remove crank handle and re-engage the fertiliz-
er drive sprocket.
NOTE: You may want to repeat the calibration proce-
dure if your results vary greatly from the seed-rate
chart.
11. When drilling, check seeding rate by noting hect-
ares drilled, amount of seed added to drill and
seed level in seed box. If you are seeding more
or less than desired. adjust rate slightly to com-
pensate for field conditions.
NOTE: When calibration is complete it is recom-
mended to remove the calibration tray, turn end-for-
end, rotate up-side-down and place it back under the
meter. This will keep moisture from collecting in tray.
