Scraper Adjustment
Opener blade inside scrapers are spring loaded
and require no adjustment. To replace the
scraper blades, remove the rear lock nut and
slide both blades from the stem. Assemble with
new blades and replace onto stem being careful
no to overtighten lock nut.
NOTE: Do not over tighten lock nut. Be
sure scrapers move freely. Failure to
do so will result in damage to scrapers
and proper operation of scrapers.

Blade Gap Adjustment
Offset blade designs form better seed furrows
and penetrate and cut in tougher planting condi-
tions. As the blades wear, the gap between
blades will increase. Removing each blade from
the opener bracket allows the operator to take
shim washers from behind the bearing and re-
adjust the blade gap for better performance.
Maintain a 1/8" - 3/16" clearance between
blades, measuring at the pinch point. Inade-
quate clearance will increase wear on the inside
of the lead blade and mean quicker replace-
ment.
NOTE: The right blade is installed with a right
hand threaded bolt. The left blade is installed
with a left hand threaded bolt. The lead blade is
reversed on each half of the drill.
Tandem Wheel Drive Clutch
Tandem wheels that drive a seed shaft are
manufactured with a friction disc type clutch. If
the drive wheel encounters a hole, ridge, or
other situation that may cause a delay in ade-
quate ground contact, the other wheel will "take
over" driving the seed shaft. During turns, or in
the folding operation, it is necessary that the
non-drive wheel can free wheel. This clutch
should require no adjustment.
The tire is bolted to the hub using four stud bolts
and four through bolts with tapered nuts for
thread protection. If the wheel must be removed
for service, tighten the four lock nuts on the
rubber springs to snug. Remove the tapered
nuts on the stud bolts coming through the hub,
and remove all eight stud bolts to remove tire.
The wheel hub may now be removed by remov-
ing dust cap and castellated nut on spindle.
After replacing wheel hub and tightening onto
spindle for proper bearing drag, install longer
stud bolts in hole aligning clutch and replace
tapered nuts. Release spring pressure by
loosening the four lock nuts, leaving two threads
on the outer end of the spring bolt.

CAUTION!
At the start of a new drilling season,
or anytime the drill is going to be
used, especially if the drill has been
stored out in the weather all winter long, make
sure the clutch drive is not frozen up. Failure to
do this will result in damage to clutch assembly.
To make sure the clutch is not frozen up, tighten
up the clutch bolts. This should free the disc
torque limiter. If not, use a knife to free the
torque limiter from one or the other. Reset
clutch back to where it was. DO NOT use any
oil or penetrating oil of any kind.
