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 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. See “
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-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)
If operating at high down-pressures, see “
Reduce hydraulic down pressure on openers. See “
Check press-wheel adjustment. See “
Opener Depth (Press Wheel Height)
Front of openers dropping
too low in hard or
minimum-till conditions
Set opener-frame bolt in top hole. See “
Reduce hydraulic down pressure on openers. See “
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 “
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.
Pressure gauges show
pressure when the
openers are raised
Check if hoses are routed incorrectly between pressure-control valve and opener-lift cylinders.
Transport lock channels
will not stay in position for
transport
Check u-shaped clip in lock channel. Clip must clasp cylinder rod securely. If necessary, 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
functioning 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.
Check chain length and adjustment. See “
Reverse blade to pull dirt in or throw dirt out depending on soil conditions.
