Symptom	Problem	Solution
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.

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.
