Tubes and Openers Clogging.
|
Using trashy seed.
|
Use clean seed. Filter seed thru optional lid screens.
|
|
|
Stopping drill in field and letting drill roll backward, filling the bottom of boot with dirt.
|
Raise furrow openers before stopping drill. Do not permit drill to roll backward if it is necessary to stop without raising furrow openers.
|
|
|
Seed left in openers. Seeds will swell over time.
|
Clean out seed before parking overnight.
|
|
Mud builds up on press wheels and wheels stop turning.
|
Too much down pressure.
|
Remove spring pressure from press wheels.
|
|
|
Field too wet.
|
Wait until field dries.
|
|
Poor Opener Penetration.
|
Excessive down-pressure.
|
Decrease down-pressure if rear wheels lift off ground during operation.
|
|
|
Residue laying in bunches.
|
Spread residue evenly across field.
|
|
|
Excessive residue.
|
Adjust gauge wheel for deeper operation and/or increase down pressure.
|
|
|
Dull disk openers.
|
Sharpen or replace openers.
|
|
|
Disk opener worn too small.
|
Replace disk openers.
|
|
Furrow Not Closing.
|
Closing wheel not adjusted properly.
|
Reposition closing wheel laterally. See POSITIONING CLOSING WHEELS in Preparing The Machine section.
|
|
|
Field is wet.
|
Adjust closing wheel spring pressure. See ADJUSTING PRESS WHEEL AND CLOSING WHEEL DOWN FORCE in Preparing The Machine section.
|
| Symptom |
Problem |
Solution |
|
Furrows covered with solid ribbon of soil.
|
Field is wet.
|
Allow field to dry. A solid ribbon of soil (instead of loose soil) over the seed will cause erratic or poor emergence.
|
|
Bunching and Skipping.
|
Stopping drill in field.
|
Stop at row ends.
|
|
Furrow Covered Too Deep With Loose Soil.
|
Openers throwing loose soil.
|
Decrease opener down pressure. See ADJUSTING OPENER DOWN-PRESSURE in Operating The Machine section.
Operate slower.
Raise seed boot on front rank.
|
|
Residue Buildup In Front of Openers.
|
Residue wedged between seed boot and disk opener.
|
Move boot to top hole. See POSITIONING SEED BOOTS in Preparing The Machine section.
Decrease opener down pressure. See ADJUSTING OPENER DOWN-PRESSURE in Operating The Machine section.
|
|
Uneven Opener Penetration.
|
Inconsistent opener adjustments.
|
Adjust openers alike.
|
|
Uneven Seed Depth.
|
Residue laying in bunches.
|
Spread residue evenly across field.
|
|
|
Inadequate down pressure.
|
Increase down pressure to keep gauge wheel in contact with the ground.
|
|
|
Excessive down pressure.
|
Decrease down pressure if rear wheels lift off ground during operation.
|
|
|
Seed boots worn.
|
Install seed boot in lower mounting hole for additional life and/or replace seed boot.
|
| Symptom |
Problem |
Solution |
|
Plugged air hoses or manifolds.
|
Air volume too low.
|
Increase fan speed.
|
|
|
Ground speed too fast.
|
Reduce ground speed or metering rate.
|
|
|
Secondary hoses routed flat or uphill.
|
Reroute hoses correctly.
|
|
|
Foreign material blocking air system.
|
Clean air system.
|
|
|
High relative humidity.
|
Use talc or wait for drier conditions.
|
|
Plugged seed boots.
|
Backing or turning with openers in ground.
|
Raise openers before backing or turning.
|
|
|
Boots worn out.
|
Replace boots.
|
|
Uneven seed distribution between runs.
|
Air volume too low.
|
Increase plenum pressure.
|
|
|
Blockage in air lines or manifolds.
|
Clean air system.
|
|
|
Variation in secondary hose lengths or routing.
|
Trim hoses to uniform lengths and reroute correctly.
|
|
|
Improper assembly of header ring or air system.
|
Reassemble correctly.
|
|
Seed damage.
|
Air volume too high.
|
Reduce plenum pressure.
|
|
|
Seeds too dry.
|
Use fresh seeds.
