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 posi-
tion.
Spring pressure on openers could be improperly adjusted causing opener
to not penetrate low spots.
Check for trash or mud build-up on Seed-Lok Wheel.
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 move-
ment.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, lessen down pressure on
disk opener.
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",
Section 2, page 6.
Check gauge wheel size. Proper size is 9.00L x 24".
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.
See Operator’s Manual for instructions on calculating seed rate.
Excessive seed cracking Use slower drive type 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. Proper inflation is listed in the "Tire Inflation Chart".
Section 2, page 6.
Check gauge wheel tire size. Proper size is 9.00L x 24".
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 Section 4, page 12 in "Seed Rate
Adjustments".
Check to be sure your acremeter is for your width of drill.
Uneven seeding depth See section on depth adjustments.
Press Wheel not compacting the soil
as desired Reset press wheel depth, see seeding and press wheel adjustments sec-
tions.
2" x 13" Double "V" press wheel angles may need to be adjusted.
Down pressure on disk openers is not enough.
