Troubleshooting
Problem Solution
Uneven seed spacing or uneven
stand Check for plugging in feed cup.
Check to see if seed tubes are plugged.
Reduce ground speed.
Check opener disks to see they turn freely.
Use faster drive type speed and close feed cup flutes to a more narrow position.
Hydraulic pressure on openers set too low causing opener to not penetrate.
Check for trash or mud build-up on Seed-Lok Wheel.
Hydraulic pressure on openers set too high causing gauge wheels to loose con-
tact with ground
Opener disks not turning freely Check for trash or mud build-up on disk scraper. Readjust scraper.
Check to see if scraper is adjusted too tight and is restricting disk movement.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, lessen down pressure on
opener hydraulics.
Check press wheel adjustment for seeding depth.
Actual seeding rate
is different than desired Check tire pressure. Proper inflation is listed in the Tire Inflation Chart in the
“Appendix” section on page 64.
Check wing gauge wheel size. Proper size is 9.5L-15 6ply.
Seed treatment will affect seeding rate if the chemicals build up in seed cup.
Unless cleaned regularly, this build-up can cause breakage of the feed shaft.
Check drill box setting.
Heavier or lighter than average seed weight being planted. See Operator’s Manual
for instructions on calculating seed rate.
Excessive seed cracking Use slower drive speed and open flutes in feed cup to a wider position.
Position feed cup handles to a lower notch.
Acremeter doesn’t measure accu-
rately Check tire pressure. Proper inflation is listed in the Tire Inflation Chart in the
“Appendix” section on page 64.
Check gauge wheel tire size. Proper size is 9.5L-15 6ply.
Check planting operation for excessive overlap or gaps between passes.
Loose soil conditions and slippage will cause variations in acres registered.
To check accuracy of acremeter see Seed Rate Calibration in the “Adjustments”
section on page 32.
Check to be sure your acremeter is for your drill.
Uneven seeding depth See section on depth adjustments.
See the “Drill Preparation and Setup” section for Tractor Draw Bar Hook-Up on
page 17, and Leveling The Drill on page 12.
Press wheel not
compacting the soil as desired Reset press wheel depth, see the “Adjustments” section on page 32 for seeding
and press wheel adjustments.
Hydraulic down pressure on disk openers is not enough.
