Uneven seeding depth See “Opener Depth (Press Wheel Height)” on page 38.
See “Opener Frame Down-Force” on page 32.
Check that drill tongue matches tractor drawbar height. See “Hitch Preparation” on
page 13.
Chain debris/retainer clip Be sure retainer clip is facing opposite way of chain travel.
Press wheel not
compacting the soil as
desired
Reset presswheel depth. See “Opener Depth (Press Wheel Height)” on page 38.
Increase down pressure. See “Opener Frame Down-Force” on page 32.
Grain box not emptying
evenly
Certain models do not have the same number of seed cups between each bulkhead
divider. The section with more seed cups empties faster.
Press wheel or openers
plugging
Consider soil conditions. Drilling in damp or wet conditions can increase this problem.
Reduce down pressure. See “Opener Frame Down-Force” on page 32.
Do not back up or allow drill to roll backward with openers in ground.
Check Seed-Lok
®
wheels for mud accumulation. Lock up wheels if necessary. See
“Seed-Lok
®
Seed Firmer Lock-Up” on page 37.
Seed cup sprockets
locked up or seed drive
shaft twisted
Check for foreign material lodged in seed cup sprockets.
Check for buildup of dried liquid insecticide in seed cups. Remove the build up by
disassembling each seed cup and scraping the foreign substance from the turning
surfaces.
Openers drill too deep
(Bulldozing)
If operating at high down-pressures, See “Opener Frame Down-Force” on page 32.
Reduce down pressure on openers. See “Opener Frame Down-Force” on page 32.
Check presswheel adjustment. See “Opener Depth (Press Wheel Height)” on
page 38.
Openers raise when
tractor hydraulic lever
is held forward and
lower when lever is held
back
Reverse hydraulic hoses at tractor quick couplers.
Opener frames do not
float over uneven
terrain
Check that hydraulic circuit is in Neutral.
Marker Disk Not Marking Marker arm cylinder may not be fully extended. Move circuit remote lever in opener
lower direction briefly.
Marker disk angle may need adjustment for conditions. See page 33.
Markers Won’t Unfold Transport pins may be in place. See page 26 for safe field preparation steps.
Sequence valve speed adjusters (needle valves) may be too tight or closed. Readjust
to increase marker unfold speed.
Markers Won’t Fold Sequence valve speed adjusters (needle valves) may be too tight or closed. Readjust
to increase marker fold speed.
Marker Movements Tardy,
Sudden, Jerky or
Unexpected
Check all hoses and fittings for leaks and loose connections.
Check tractor hydraulic oil level.
Check all bolts and pins.
Perform a circuit bleed (page 43) if any hydraulic problems were corrected.
