Section 6 Troubleshooting
Problem Solution
Uneven bean spacing or uneven stand a. Check for trash in seed cup.
b. Check to see if seed tubes are plugged.
c. Reduce ground speed.
d. Check planter disks to see they turn freely.
e. Use faster drive type speed and close feed cup flutes to a more
narrow position.
Planter disks not turning freely a. Check for trash or mud buildup on disk.
b. Check row frame for possible damage.
Actual seeding rate is different than
desired. a. Check tire pressure. Proper inflation is listed on page 6 in “Tire In-
flation Chart”.
b. Check tire size. Proper size is 11L x 15".
c. Liquid seed treatment will affect seeding rate if the chemicals build
up in feed cup. Unless cleaned regularly, this build up can cause
increased torque and breakage of the feed shaft.
d. Check drive type. See "Section 4 Seed Rate Chart" page 17.
e. See instructions on calculating seed rate.
Excessive seed cracking Change drive type to a slower speed and open flutes in feed cup to a wider posi-
tion.
Acremeter doesn’t measure accu-
rately a. Check tire pressure. Proper inflation is listed in “Section 2 Tire In-
flation Chart” on page 6.
b. Check tire size. Proper size is 11L x 15".
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 "Section 4 Seed Rates"
page 16.
Uneven seeding depth Check to see that all planter drills are adjusted the same.
Press Wheel not compacting the soil
as desired Check the spring tension bolt on the back of the press wheel arm. The spring
pressure can be adjusted heavier or lighter.
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.
b. If your drill has multiple boxes, check adjustment levers on each
box to see that they are set on the same indicator number.
Feeder cup sprockets locked up or
twisted a. Check for foreign matter lodged in one or more feeder drive shaft
feeder cups.
b. Liquid insecticide from bean has dried within the feed cup. Re-
move the build up by disassembling each feed cup and scrape the
foreign substance from the turning surfaces. NOTE: Liquid inocu-
lant should be applied with caution and care should be taken to
clean the feeder system after planting treated beans.
