10. Place the crank handle on the right-hand
contact drive shaft and turn the crank sev-
eral times to fill fertilizer meters. Turn
crank until fertilizer drops from each
meter. Slide fertilizer calibration tray to
the right until it reaches the stop. Tilt tray
down and use brush or rag to remove fer-
tilizer. Place tray back under meter and
secure in place.
11. Turn crank on contact-wheel shaft
counter-clockwise 32 revolutions for 1/
100 hectare fertilizer rate. While turning,
check that the fertilizer meters have plen-
ty of fertilizer coming into them. (For a
more accurate calibration it is recom-
mended to lower drill to planting position.
Drive forward a short distance so meters
fill with fertilizer. Empty calibration tray
into a container. Place tray back under
meter and secure in place. Drive forward
a measured distance of 33.3 meters.)
12. Weigh metered fertilizer, subtracting con-
tainer weight. Multiply weight by 100 to
determine total kilograms per hectare fer-
tilized. If this figure is different than de-
sired, adjust fertilizer rate handle
accordingly.
13. When through with calibration, use the
crank handle to rotate the calibration
shaft index collar to the right.
NOTE: Decals located next to calibration
shaft index collars indicate proper rotation for
calibration and field operation.
14. Remove crank handle and re-engage the
seed drive sprocket.
NOTE: You may want to repeat the calibration
procedure if your results vary greatly from the
fertilizer-rate chart.
15. When drilling, check fertilizer rate by not-
ing hectares drilled, amount of fertilizer
added to drill, and fertilizer level in fertiliz-
er box. If you are fertilizing more or less
than desired, adjust rate slightly to com-
pensate for field conditions.
NOTE: When calibration is complete it is rec-
ommended to remove the calibration tray, turn
end-for-end, rotate upside down and place it
back under the meter. This will keeep mois-
ture from collecting in tray.
