NOTE: On some tractors, fan speed surges when warning lights
flash. This usually happens on tractors with electro-hydraulic controls,
but also occurs with other control systems. This is not considered
a problem because flashing warning lights are normally turned OFF
when seeding.
| Symptom | Problem | Solution |
|
Plugged air hoses or manifolds.
| Air volume too low. |
Increase fan speed.
|
| |
Ground speed too fast.
|
Reduce ground speed or
meter rate.
|
| |
Foreign material blocking air system.
|
Clean air system hoses
and manifold openings.
|
| |
Unbalanced air flow (Double-Shoot System).
|
Adjust damper position.
|
| |
Secondary hoses routed flat or uphill.
|
Reroute hoses correctly.
|
| |
Non-compatible fertilizers.
|
Do not mix Urea with Ammonium
Nitrate fertilizer.
|
| |
High humidity.
|
Use moisture resistant
fertilizer or wait for drier conditions.
|
| |
Leaking air manifold.
|
Inspect meter seals for
tight fit.
Caulk manifold pieces together.
|
|
Uneven product distribution between runs.
| Air leak between manifold and meter. |
Check manifold to meter
seal.
|
| |
Product level too low for accurate metering.
|
Do not run tank empty.
Refill sooner.
|
| |
Air volume too low.
|
Increase fan speed.
|
| |
Meter tuning rings not installed, or wrong number installed.
|
Install correct number
of tuning rings for secondary header ports.
|
| |
Blockage in air lines or manifolds.
|
Clean air system and manifold
openings.
|
| |
Improper assembly of header ring.
|
Reassemble correctly.
|
| |
Manifold slide not fully positioned in top-shoot or
bottom-shoot position
|
Check for foreign material
in slide path, manifold passages, and slide openings.
|
| |
Variation in secondary hose lengths or routing.
|
Trim hoses to uniform
lengths and route correctly.
|
| |
Unbalanced air flow (Double-Shoot System).
|
Adjust damper position.
|
| |
Tank not pressurized.
|
Inspect lid seal for leaks.
Clean manifold screens.
Clean tank pressurization
hoses.
Clean manifold end caps and air control valves
