Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed for both
drill and implement.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
General Description
Drill hydraulic functions are on two or three separate
circuits, two of which may be shared with cart functions.
See “Hydraulic Control Overview” on page 15. Once
set up, routine drill operations require setting valve
handles on the air cart and one on the drill.
Planting Operation
Via an adjustable implement lift switch on the drill, the
NTA3010 and NTA3510 control the meter drive clutch on
the air cart, turning it on and off as the drill is lowered
and raised.
Weight transfer is hydraulically equalized between center
section and wings. The system is switched on and off by
a cab-controlled solenoid valve.
Seed is delivered to the row units by air, powered by the
fan on the air cart. Seed rate is determined by air cart
setup, and the cart meter rate self-adjusts for changes in
ground speed. Seeding stops when motion stops or the
drill is raised.
The metered seed is carried by air through the hoses to
the distribution towers on the implement. These towers
then divide the air and seed into individual rows.
There are drill adjustments for wing weight transfer, row
unit setup, seeding depth and furrow coverage.
