|
Grain tubes and furrow openers clogging
|
Using trashy seed or lumpy fertilizer
|
Use clean seed and dry, free-flowing fertilizer.
|
|
|
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
|
Lower openers to clean out seed before parking overnight.
|
|
Mud builds up on press wheels and wheels stop turning
|
Field too wet
|
Remove spring pressure from press wheels.
Wait until field is drier.
|
|
|
Press wheel not centered in furrow
|
Adjust laterally to center in furrow by removing spacer or adding washers.
|
|
Poor opener penetration
|
Hard ground conditions
|
Add tractor weights and increase down-pressure.
|
|
|
Excessive down-pressure
|
Decrease down-pressure if left-hand rear wheel is lifting 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 (may need to add tractor weights).
|
|
|
Dull disk blades
|
Sharpen or replace blades.
|
|
|
Disk blade worn too small
|
Replace disk blades.
|
|
Furrow Not Closing
|
Closing wheel not adjusted properly.
|
Adjust closing wheel laterally.
|
|
|
Field is wet.
|
Adjust closing wheel spring pressure.
|
| 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.
|
|
|
Convoluted seed hoses sag when drilling at shallow depths.
|
Slide convoluted hose lower on steel seed tube to tighten hose.
|
|
Furrow Covered Too Deep With Loose Soil
|
Rear openers throwing loose soil.
|
Decrease opener down pressure.
Operate slower.
Raise boot on front rank.
|
|
Trash Buildup In Front of Openers
|
Trash wedged between seed boot and disk blade.
|
Move boot to top hole.
Decrease opener down pressure.
|
|
Uneven Seed Depth.
|
Residue laying in bunches.
|
Spread residue evenly across field. (Gauge wheel gauges from top of residue encountered.)
|
|
|
Inadequate down pressure.
|
Increase down pressure to keep gauge wheel in contact with the ground and/or install tractor weights.
|
|
|
Excessive down pressure.
|
Decrease down pressure if left hand rear wheel is lifting off ground during operation, or install tractor weights.
|
|
|
Seed boots worn.
|
Install seed boot in lower mounting hole for additional life and/or replace seed boot.
