PROBLEM POSSIBLE CAUSES POSSIBLE SOLUTIONS
page 6-5
Product buildup/accumulation in
air passage ways (high moisture
product).
1. Humid air conditions.
2. Moisture sensitive product.
3. Moisture condensation in the
tank.
4. Product left in tank too long.
1. Change to a different product.
2. A full tank reduces potential for
this problem.
3. Do not place product in tank
until time of use.
4. Do not place product in tank
until time to use.
Product buildup/ accumulation in
air passageways (high levels of
moisture in the air).
1. Humid air conditions.
2. Water in the fan housing at
start-up.
3. Moisture /condensation in
hoses at start-up.
1. Drain fan housing after a rain.
2. Run system without product to
dry lines.
3. Run system without product to
dry lines.
Seed damage. 1. Air velocity too high on short
(center) primary hoses.
2. Wrong meter roller for large
products.
3. Product too dry.
1. Even out primary hose length.
2. Use coarse or extra coarse
meter roller.
3. Use higher moisture content
product.
Hoses wearing out. 1. Air velocity too high
(see above).
2. Tight curves in hoses.
3. Hoses not being rotated.
4. Abrasive product.
1. (See above).
2. Reroute hoses for longer
bends.
3. Rotate hose seasonally for
longer life.
4. Change product or accept
wear.
Inaccurate seed placement (seed
tool not set properly).
1. Back to front depth difference.
2. Center to end depth difference.
1. Level seed tool back to front.
2. Level seed tool center to end.
Inaccurate seed placement -
product blowing out of ground.
1. Air velocity too high (see
above).
2. Insufficient seed depth
placement.
3. Air flow too concentrated.
4. Too slow travel speed.
1. (see above).
2. Increase seeding tool depth.
3. Use spreading opener.
4. Increase tool speed.
