Introduction
Great Plains welcomes you to its growing family of new
product owners. Your 6 Meter No-Till Air Drill has been
designed with care and built by skilled workers using
quality materials. Proper setup, maintenance, and safe
operating practices will help you get years of satisfactory
use from the machine.
Before placing the machine into service for the first time,
read and understand this manual, in particular the
“Important Safety Information”, pages 5 to 24. Have
all operators read this manual before allowing them to
work with the machine.
Description of Unit
The NTA607 or NTA2007 is a pull-type integrated air drill
seeder. The implement folds for narrow 3 m (119 inch)
transport.
A hydraulic fan supplies the material delivery system.
Ground-driven fluted shafts below the hoppers meter the
seed or fertilizer (the materials) into the air flow. Meter
chambers and tower manifolds evenly divide the material
flow, and deliver equal volumes to each opener row.
The cart has single or dual hoppers for separate or
simultaneous delivery of seed and/or granulated dry
fertilizer. A single-hopper configuration may have liquid
fertilizer saddle tanks. Each hopper has an independent
metering system with user-preset infinite ratio
gearboxes. Console-controlled variable rate meter
servos are optional.
The NTA607 or NTA2007 has double-disc Series 07
openers, suitable for conventional till and, minimum-till
conditions. With optional coulters, the drill is suitable for
moderate no-till conditions.
Brakes are standard on model NTA607 and optional on
model NTA2007. Service brakes are operated by air or
hydraulic lines to the tractor.
Hydraulic weight transfer (of cart weight to implement,
and from implement centre section to wings) is standard.
Other options include field markers, tramline kits, high
rate or small seeds flutes, and alternate discs, scrapers
and seed firmers.
Do not modify the drill except as instructed by Great
Plains. Do not use attachments other than as provided
by or authorized by Great Plains.
Intended Usage
Use the NTA607 or NTA2007 to seed and fertilize
production-agriculture crops only.
The intended use requires that safety features are
unimpaired, that machine systems be in proper working
order, and that the material rates have been correctly
configured and verified. Use only Great Plains
authorized replacement parts.
Faults in safety features, including missing or illegible
safety decals, must be remedied prior to machine use.
To keep the machine in proper working order, comply
with operating instructions, perform periodic
maintenance, and repair or replace worn or damaged
parts.
This is a volumetric seeding implement. The provided
seed rate charts (manual 167-085B) are based on
materials which likely vary from yours. Grain size, grain
shape, density, surface texture, foreign matter,
treatments, coatings, humidity, field speed, soil
conditions and normal wear on tires and meters cause
rates to vary from the charts. Calibration is essential for
satisfactory results.
