TROUBLE SHOOTING
PROBLEM SOLUTION
1. Uneven seed spacing or uneven a. Check for plugging in seed cup.
stand b. Check to see if seed tubes are plugged.
c. Reduce ground speed.
d. Check opener disks to see they turn freely.
e. Use faster drive type and close feed cup flutes to a more narrow
position.
f. Spring pressure on openers could be improperly adjusted causing
opener to not penetrate low spots.
g. Check for trash or mud build-up on Seed-Lok Wheel, refer to op-
tional equipment section.
h. Check to see if the drive clutch is fully engaged when openers are
lowered.
2. Opener disks not turning freely a. Check for trash or mud build-up on disk scraper. Readjust
scraper.
b. Check to see if scraper is adjusted too tight and is restricting disk
movement.
c. Check disk bearings.
d. Check opener frame for possible damage.
e. If opener disks turn freely by hand but not in field, lessen down
pressure on disk opener.
f. Check press wheel adjustment for seeding depth.
3. Actual seeding rate is different a. Check tire pressure. Proper inflation is listed on page 1-4
than desired in "Tire Inflation Chart".
b. Check tire size. Proper size is 7.50" x 20".
c. Seed treatment will affect seeding rate if the chemicals build up in
seed cup. Unless cleaned regularly, this build up can cause break-
age of the feed shaft.
d. Check sprocket drive type.
e. See Operator’s Manual for instructions on calculating seed
rate.
4. Excessive seed cracking a. Use slower drive type and open flutes in feed cup to a wider posi-
tion.
b. Position feed cup handles to a lower notch.
5. Acremeter doesn’t measure a. Check tire pressure. Proper inflation is listed on page 1-4 in
accurately "Tire Inflation Chart".
b. Check tire size. Proper size is 7.50" x 20".
c. Check planting operation for excessive overlap or gaps between
passes.
d. Loose soil conditions and slippage will cause variations in acres
registered.
e. To check accuracy of acremeter, see page 5-1 on "Seeding Ad-
justments".
f. Check to be sure your acremeter is for your width of drill.
6. Uneven seeding depth a. See section on depth adjustments.
7. Press Wheel not compacting the a. Reset press wheel height, see seeding and press wheel
soil as desired adjustments sections.
b. 2" x 13" Double "V" press wheel angles may need to be adjusted.
c. Down pressure on disk openers is not enough (Refer to section on
"Hydraulic Depth Control".
8. Grain box not emptying evenly a. Certain models do not have the same number of seed cups be-
tween each divider of bulkhead. The section with the larger num-
ber of cups will empty sooner.
