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 contact 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. See “ Hydraulic Diagrams ” on page 99.
Check wing gauge wheel size. Proper size is 265/70B 16.5 NHS skid steer.
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
accurately
Check tire pressure. See “ Hydraulic Diagrams ” on page 99.
Check gauge wheel tire size: 9.5L-15 6 ply or 265/70B 16.5 NHS skid steer.
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 “ Main Box Seed Rate Calibration ” in the Seed Rate
Manual.
Check to be sure your acremeter is for your drill.
Uneven seeding depth
See “ Adjustments ” on page 46.
See “ Hitching ” on page 17, and “ Leveling the drill ” on page 74.
Press wheel not compacting
the soil as desired
Reset press wheel depth. See “ Opener Depth (Press Wheel Height) ” on page 58.
Hydraulic down pressure on disk openers is not enough.
Grain box not emptying evenly
Certain models do not have the same number of seed cups between each divider of
bulkhead. The section with the larger number of cups will empty sooner.
If drill has multiple boxes, check drive sprocket arrangement on each box to see that they
are set the same.
