1. Hydraulic Fan - The fan generates the air flow
required to deliver material to the rows. Speed is
adjusted using the tractor circuit. Output is
monitored with rpm (2), pressure gauge (5) and
pressure sensor (8).
2. Fan RPM Sensor - The terminal reports fan rpm
based on this sensor. Although it is accurate for
rate, it cannot detect a fan running in reverse.
3. Manifold Gates (page 53) - There are two gates
only on dual-hopper drills. They control airflow
balance between the meters. They may need
adjustment with dissimilar material metering.
4. Manifold Pressure Gauge(s) (page 59) - There
is one gauge per hopper, mounted for
observation from the tractor cab. These report
whether or not the air system is within
recommended limits. On dual-hopper systems,
the gauges assist in setting the manifold
gates (3).
5. Fan Manifold (page 53) - Fan air is divided (or
further divided) into equal flows for each meter
inlet port (5).
6. Hopper (page 42) - Material (seed or fertilizer)
flows into the top of the seed meter (9).
7. Pressure Balance Lines - Each hopper
contains an internal pressure-balancing system
to equalize pressure above and at the base of
the material.
8. Hopper Pressure Sensor - This sensor signals
the terminal, which can alarm if the hopper
pressure goes out of limits. A dual hopper drill
has two sensors.
9. Seed Meter - The meter combines material with
air flow. It also has features for rate range,
calibration and clean-out.
10. Metering Shaft - Four (optionally two or three)
sets of flute stars control the flow of seed from
the hopper into the air streams.
11. Meter Outlet Ports - Material falls from the
meter flutes (10) into the air streams flowing from
inlet manifold to outlet ports. Each port is a
separate compartment.
12. Diverter - Seed is distributed evenly from the
seed meter(s) through hoses to the towers.
13. Primary Seed Hose - Four (single-hopper) or
eight (double-hopper) hoses deliver seed from
the meters(9) to the distribution manifold (12).
14. Distribution Tower - The riser tube and
distribution rings evenly divide the primary hose
material flow into multiple secondary hose (15)
flows. There are two towers on single-hopper and
four towers on double-hopper drills.
15. Secondary Seed Hose - These hoses deliver
material from a tower outlet port to a seed tube
(17) or fertilizer tube (18).
16. Tramline Diverters (Option, page 104) - The
tramline diverters are mounted on the under side
of the towers.
17. Opener Seed Tube - Seed from hopper
I
and
hopper
II
on single-shoot drills is delivered
in-furrow ahead of the seed firmer.
18. Opener Fertilizer Tube (page 67) - On a
dual-hopper double-shoot drill, the material from
hopper
II
is delivered to this tube above the seed
firmer and furrow.
