Note: On the 605NT or 606NT you can also rotate the
gearbox input jackshaft by means of a wrench or
socket. You may need to remove the acremeter.
Use same number of rotations when turning the
gauge wheel jackshaft, gearbox input jackshaft or
tire.
Note: On the 3P605NT or 3P606NT you can also rotate
the gearbox drive shaft with wrench or socket.
6. Pull the Native Grass seed hoses off the top of three
opener seed tubes, at the top of the openers. Place
the hoses into sample containers.
7. If the Main Box or optional Small Seeds box are
loaded, disconnect their drive or set their rates to
zero (unless you are simultaneously calibrating
multiple boxes).
8. Load seed above the rows to be sampled. Load well
more than the expected sample size.
9. Rotate the crank several turns to ensure that the
drives and seed cups are engaged, working properly,
free from foreign material, and that seed is flowing
steadily from the meters. Stop.
10. Note the current reading of the acremeter, unless
removed or you do not plan to rely on it for the
calibration.
11. Empty the sample containers back into the seed box,
and place them back under the three hoses to gather
metered seed.
12. Turn crank at a steady rate until one tenth acre is
tallied on acremeter. While turning, check that cups
have ample seed coming into them.
13. Weigh metered seed. Subtract initial weight of
container(s).
14. Divide the net seed weight by three. Multiply by
number of openers on your drill, and then by ten, to
determine the total of pounds per acre seeded.
