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.

Remove spring pressure from press wheels.

Field too wet.

Wait until field dries.

Increase down pressure. See Adjust Opener Down Force—Tractors with Closed Center Hydraulic Systems in Operating Machine—Air Tool section.

Two-Rank Machine: Add Quik-Tatch™ weights. See Install Frame Quik-Tatch™ Weights on Wings in Preparing Machine section.

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. (Two-Rank Machine: May need to add weights.)

Dull disk openers.

Sharpen or replace openers.

Disk opener worn too small.

Replace disk openers.

Reposition closing wheel laterally. See Position Closing Wheels in Preparing Machine section.

Field is wet.

Adjust closing wheel spring pressure. See Adjust Press Wheel and Closing Wheel Down Force in Preparing Machine section.

Allow field to dry. A solid ribbon of soil (instead of loose soil) over the seed can cause erratic or poor emergence.

Stop at row ends.

Decrease opener down pressure. See Adjust Opener Down Force—Tractors with Closed Center Hydraulic Systems in Operating Machine—Air Tool section.

Operate slower.

Two-Rank Machine: Raise seed boot on front rank.

Move boot to top hole. See Adjust Seed Boots in Preparing Machine section.

Decrease opener down pressure. See Adjust Opener Down Force—Tractors with Closed Center Hydraulic Systems in Operating Machine—Air Tool section.

Adjust openers alike.

Spread residue evenly across field.

Inadequate down force.

Increase down pressure to keep gauge wheel in contact with the ground, or install weights (two-rank machine).

Excessive down force.

Decrease down pressure if rear wheels lift off ground during operation, or remove weights (two-rank machine).

Seed boots worn.

Seed boot Installed in lower mounting hole for additional life, or replace seed boot.

Increase blower speed.

Ground speed too fast.

Reduce ground speed or metering rate.

Secondary hoses routed flat or uphill.

Correctly Reroute hoses .

Foreign material blocking air system.

Clean air system.

High relative humidity.

Use talc or wait for drier conditions.

Raise openers before backing or turning.
