Section 7 Troubleshooting
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.
Press wheel or openers plugging Drilling in damp or wet conditions may increase this problem.
Reduce down pressure on openers.
Do not back up drill in the field, or stop and allow drill to roll backwards with
openers in the ground.
If using double "V" press wheels, adjust angle bar.
Check Seed-Lok Wheel.
Raising and lowering drill is rough or
uneven Lubricate wheel arm pivot casting.
Check hydraulic fittings or leaks.
Rephasing cylinders not properly bled. Refer to "Bleeding the Hydraulic Lift-
ing System" on page 9. When raising the drill at the end of the field, the lift-
ing cylinders should be fully extended to insure that they are always
rephased. If drill is only raised enough to lift openers out of ground, lift cyl-
inders may eventually get out of sequence and cause uneven seeding depth.
Feed cup sprockets locked up or
twisted feed drive shaft Check for foreign matter lodged in one or more feeder cup sprockets.
Liquid insecticide from seed has dried within the feed cups. Remove the
build up by disassembling each feed cup and scrape the foreign substance
from the turning surfaces. NOTE: Liquid insecticide should be applied with
caution and care should be taken to clean the feed system after drilling
treated seeds.
Coulters not going deep enough Check weight chart on page 22 and add additional weight.
Lower coulter spring bars on tool bar. {Only in tire tracks.}
Check cylinder depth stop, refer to page 22.
Coulters and drill going to deep Check weight chart on page 22 and remove weight if necessary.
Set press wheels to a shallower depth.
Check cylinder depth stop, refer to page 22.
Hoses plugging in no-till conditions Drill at a slight angle to the rows.
