OPERATION AND MAINTENANCE
Seed Rate Adjustment
1. The seeding rate is adjusted for each section with
the threaded seed rate adjustment at one end of
each drill section. The end seed meter next to the
adjustment has an indicating scale for reference.
Read the scale along the outside edge of the seed
meter to determine the setting. The seeding rate
should be set the same for all sections
(See
Figure 4-10.)
a. To set the seeding rate, first determine from the
seed rate chart the meter opening for the desired
seed rate.
The seed rate chart is located inside
the lid of the center seed box (See Figure 4-11.)
b. Loosen the locking nut on the square seed shaft
from the end bushing.
c. Using a ratchet wrench extension, and 3/4”
socket, insert the socket through the hole in the
end box support to the hex-head adjustment
bushing. Turn the hex-head adjustment bushing
in or out, until the desired rate setting is obtained
along the outside edge of the seed meter.
d. Re-tighten the locking nut to secure the seed
rate setting.
NOTE
Do not force the seed meter shaft, damage will occur.
The meter will not be able to fully close if there is seed in
the box. Lube/oil the square seed shaft so that it will
easily slide through the support bearing while adjusting.
