Drill boxes not emptying evenly
Certain models do not have the same number of cups between each
divider of bulkhead. The section with more cups will empty sooner.
Press wheel or openers plugging
Consider soil conditions - may be too damp or wet.
Reduce down pressure on openers. See “Row Unit Down Pressure” on
page 43.
Do not back up or allow drill to roll backward with openers in the ground.
Check Seed-Lok wheels. If conditions are too wet, you may need to
remove the wheels.
Seed cup sprockets locked up or
twisted seed cup drive shaft
Check for foreign material stuck in the seed cup sprockets.
Check for dried liquid insecticide in seed cups. Remove the build-up by
disassembling seed cups and scraping the foreign substance from the
turning surfaces.
Drill is not pulling level (parallel to
ground, front to rear)
Readjust top hitch link to level drill.
If using pull-package or hitch equipped with a telescoping top link,
increase opener spring pressure to rock drill forward. See “Row Unit
Down Pressure” on page 43.
Gauge wheel leans to left or right
Realign brackets where gauge wheel is attached to main frame by adjust-
ing U-bolts.
Check if axle bearings are securely attached to gauge wheel arm.
Hydraulic marker functioning
improperly
Check all hose fittings and connections for air or oil leaks.
Check that the chain on the folding marker is slack when the marker is
both fully extended and raised. See “Marker Chain Adjustment” on
page 20.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
Open needle valve, cycle markers slowly and reset needle valve if
plugged.
Marker blade does not mark
Check that the marker folding linkage has enough slack to allow the
marker disk to drop into field depressions. Maximum down float should be
limited by the slot at the rod end of the marker cylinder - not by the chain.
See “Marker Setup” on page 20.
Reverse the blade to pull or throw dirt. See “Marker Adjustments” on
page 29.
Chain-debris/retainer clip
Be sure retainer clip is facing opposite way of chain travel.
