Grain box not emptying evenly Certain models do not have the same number of seed cups between each bulk-
head divider. The section with more seed cups will empty sooner.
Check that you have the same drive type set on both drill boxes.
Press wheel or openers plugging Consider soil conditions. Drilling in damp or wet conditions can increase this
problem.
Reduce hydraulic down pressure. Refer to Opener Down Pressure, “Adjust-
ments,” page 33.
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.
Refer to Seed-Lok Lock Up “Adjustments,” page 36.
Seed-cup sprockets locked
up or seed-drive shaft twisted Check for foreign material lodged in seed-cup sprockets.
Check for build-up 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) Reduce hydraulic down pressure on openers. Refer to Opener Down Pressure,
“Adjustments,” page 33.
Check press-wheel adjustment. Refer to Opener Depth, “Adjustments,” page 35.
Front of openers dropping too low
in hard or minimum-till conditions Set opener-frame bolt in top hole. See Opener Frame Adjustments, “Adjust-
ments,” page 35.
Reduce hydraulic down pressure on openers. Refer to Opener Down Pressure,
“Adjustments,” page 33.
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 lever is locked forward and openers are connected to circuit
designed for hydraulic-motor control. See Opener Operation, “Operating Instruc-
tions,” page 18.
Pressure gauges read zero when
openers are lowered and tractor
hydraulic lever is held forward Check if hoses are routed incorrectly between pressure-control valves and
opener-lift cylinders. See hose-routing diagrams under Bleeding the Hydraulics,
“Drill Preparation and Setup,” page 11.
Pressure gauges show pressure
when the openers are raised Check if hoses are routed incorrectly between pressure-control valve and opener-
lift cylinders. See hose-routing diagrams under Bleeding the Hydraulics, “Drill
Preparation and Setup,” page 11.
Transport lock channels will not
stay in position for transport Check u-shaped clip in lock channel. Clip must clasp cylinder rod securely. If nec-
essary, tighten or loosen clip by turning the bolt on clip.
Before transporting, check that hydraulic cylinders have settled against lock
channels. The weight of cylinders help hold lock channels in place.
Optional hydraulic marker func-
tioning
improperly Check all hose fittings and connections for air and oil leaks.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
If needle valve is plugged, open valve, cycle markers and reset the needle valve.
Optional marker disk does not
mark If blade does not drop down into field depressions, make sure marker cylinder is
fully extended. Refer to Marker Adjustments, “Adjustments,” page 39.
Reverse blade to pull dirt in or throw dirt out depending on soil conditions.
