Openers

Grain tubes and furrow openers plug.

High residue seed or lumpy fertilizer.

Use clean seed and dry, free-flowing fertilizer.

Bottom of boot fills with dirt.

Raise furrow openers before stopping drill. If it is necessary to stop without raising furrow openers, do not allow drill to roll backward.

Seed left in openers. Seeds 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.

Allow field to dry.

Poor opener penetration.

Hard ground conditions.

Add QuikTach ™ Weights. See INSTALL FRAME QUIKTACH WEIGHTS in Prepare Machine section.

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 field residue.

Adjust gauge wheel for deeper operation. (Add QuikTach™ weights as required.)

Increase down pressure

Dull disk openers.

Sharpen or replace disks.

Disk opener worn too small.

Replace disks.

Furrow not closing.

Closing wheel not adjusted properly.

Adjust closing wheel laterally. See POSITION CLOSING WHEELS in Prepare Machine section.

Field is wet.

Allow field to dry.

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 causes erratic or poor emergence.

Poor seed placement when drilling soybeans after corn while following old corn rows.

Opener gauge wheels ride directly on the row (over the corn root balls) and cause opener to bounce.

Use alternate opener pattern. See USING ALTERNATE OPENER PATTERN in the Service section.

Residue blowing after drilling.

Opener gauge wheels ride directly on old row, loosening the residue.

Use alternate opener pattern.

Furrow covered too deep with loose soil.

Rear openers throwing loose soil.

Decrease opener down pressure. See ADJUST OPENER DOWN PRESSURE in Operate Machine section.

Operate slower.

Raise boot on front rank.

Residue buildup in front of openers.

Residue wedged between seed boot and disk opener.

Decrease opener down pressure. See ADJUST OPENER DOWN PRESSURE in Operate Machine section.

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 QuikTach™ weights.

Excessive down-pressure.

Decrease down pressure if left hand rear wheel is lifting off ground during operation or install QuikTach™ weights.

Seed boots worn.

Install seed boot in lower mounting hole for additional life or replace seed boot.
