YOUR OWNER'S MANUAL
Avoid Accidents
Most accidents, whether they occur in
industry, on the farm, at home, or on the
highway, are caused by the failure of some
individual to follow simple and fundamental
safety rules or precautions. For this reason
most accidents can be prevented by recog-
nizing the real cause and doing something
about it before the accident occurs.
———————
Regardless of the care used in the design
and construction of any type of equipment,
there are many conditions that cannot be
completely safeguarded against without
interfering with reasonable accessibility and
efficient operation.
A CAREFUL OPERATOR
is the Best Insurance Against an Accident.
The complete observance of one simple
rule would prevent many thousands
of serious injuries each year.
That rule is:
Never Attempt to
Clean, Oil, or Adjust
A Machine While It Is In Motion.

Min-Till Drill
Setting Down Pressure
Opener pressure setting is easy and allows
separate settings for tire compaction areas to
different soil conditions from field to field. Ratchet
mechanism allows you to turn the pressure up or
down. The locking key rolls up or down the notch
gauge and locks to your desired setting from
140# to 250# per opener.
Notch 1 . . 140#
Notch 2 . . . 190#
Notch 3 . . 210#
Notch 4 . . 230#
Notch 5 . . 250#
Down Pressure Spring Adjustment
Row units that run in wheel tracks can be set
with heavier down pressure to assure solid
presswheel action. The following will help in
changing spring pressure.
1. Rotate the tool bar to raise the opener. Fold
up the walkboard to give good access to
the front of the opener.
2. Using ratchet type wrench, roll locking key
up or down notch gauge to desired setting.
Setting Seed Depth
Understanding the tool bar operation and
parallel linkage design will make setting the drill
much easier. Refer to the drawing on the next
page.
Rotating the rockershaft DOWN
sets seed depth more SHALLOW.
Each tool bar is controlled by a hydraulic cylin-
der within each wheel arm. An adjustable depth
stop sets the travel of the cylinder which in turn
determines how much the tool bar rotates.
Set depth stop in middle position as a starting
point. To set deeper seed depth, screw the
depth stop out and lengthen the cylinder travel.
The opener and presswheel relationship con-
trols the depth of seed.
When lowering the openers, be sure the tool
bar is in the full down position and the
cylinder is retracted against the depth stop.
The parallel linkage must be "set" to
achieve the desired down pressure and
depth control.
Individual presswheels may be set to correct for
wheel track compaction. Usually, these will only
need to be adjusted once if the same tractor is
pulling the drill the entire season. At the rear of
the opener, a cam rotation bracket holds the
single presswheel arm. Turn the cam toward
the "D" or "S" to achieve the desired depth
control.
LOWERING the presswheel
will set seed depth more SHALLOW.

Wobble Slot Seed Cup Adjustments and Service
The wobble slot seed cups should be checked
against the slot gauge initially and anytime service
has been performed on the seed shaft or individual
seed cups. Refer to the drawing below for proper
adjustment if repairs have been made.
To verify that all seed cups are set the same on
the shaft, start with all cups fully closed. A slight
crack between the cup halves would be considered
normal tolerance. If any individual cup is not
"zeroed out," open the slot width using the adjust-
ing handle, loosen allen set screws and adjust to
equal others on shaft.
To determine if the gauge is reflecting the correct
seed cup slot width, open the seed cups using the
adjusting handle. Notice that wobble slot halves
are positioned differently on the hex shaft. Identify
a cup that will accept a piece of ½" keystock or
other measuring device comfortably and give solid
contact against each half. It may be necessary to
turn the hex shaft slightly to position the particular
seed cup correctly. Close the slot width firmly
against the measuring device. At the cup next to
the wobble slot adjusting handle, position
the gauge to equal the slot width you have just
measured with the keystock by loosening with a
screwdriver and sliding in or out.
Before removing the keystock, make certain the
bearing located on the adjustment lever is securely
running between the shaft bushings. Adjusting
bushings must be set screwed tightly to shaft with
zero to 1/64" tolerance between the bushing and
bearing. Excess tolerance in this area will allow
the seed shaft to float from right to left, thus open-
ing and closing wobble slot and varying the seed
rate.
Small changes in rate can be made by opening or
closing slot width. To close the slot width with
grain in the box, close the slot down a maximum of
1/8" and then rotate the shaft one turn to clear the
slot. Repeat this process until the desired slot
width is selected.
Seeding rate is affected by seed size, seed
treatments, foreign material, and test weight.
Refer to seed rate charts as guidelines for
desired seeding rates.
Chain Tension on Drive Shaft
When making sprocket changes to the seed
shaft, tighten chain to leave approximately 1/2"
of flex. The final sprocket must allow the hex
shaft to slide within the sprocket when the
adjusting lever is moved. If the chain is too
tight, bowing and binding of box end will occur
making seed cup adjustment difficult. Lightly
lubricate the shaft where the sprocket will slide.
DO NOT OVERTIGHTEN CHAIN.

Calibration, Seed Rates and Sprocket Box
Calibration/Drilling Rates
Planting the right rate can be frustrating. Some-
times the end result is not what the rate chart
indicates. Seeding rate is affected by seed size,
seed treatments, foreign material, test weight,
and tire air pressure.
1. Always plant clean seed.
2. Check tire air pressure.
3. Seed treatments vary by type and time of
application.
Some seeds are treated at the processor. Drill
box treatments are common methods of applica-
tion. Each of these can "gum" up the wobble slot
cup halves and reduce final seeding rate.
Treated seed often flows differently than non-
treated seed.
A general method for checking quantities drilled
is as follows:
1. Set drill for desired seeding rate.
2. Fill the box level; then pull drill for a short
distance to settle seed. Refill box exactly
level full.
3. Drill a calculated one acre.
4. Carefully weigh the seed required to refill the
box level full.
5. Compare the amount used versus that stated
on the rate chart.
6. Adjust seeding rate by changing the sprocket
combination or wobble slot width.
One method involves catching seed from one or
more seed cups and utilizing a density scale to
determine actual rates. These scales are com-
mercially available, inexpensive and very easy to
use. Information can be obtained from
CrustBuster®/Speed King, Inc.
Sprocket Box Operation
The sprocket box design will enable the operator
to set a wobble slot width once for a given seed
size and change rates by changing the speed of
the seed shaft. Choose a range of seeding rates
that you wish to operate in, set the slot width as
indicated by the chart and simply change knob
position with the slide handle to effect seed rate.
A narrow slot width will produce more even
distribution and spacing in the row.
When changing derailleur, be sure openers
are rotated out of ground.
To change position, move throw-out lever toward
the rear to disengage the chain from the lower
sprocket. Pull the spring loaded collar outward
with two fingers and slide side to side to the
desired gear position. Pull throw-out lever for-
ward to re-engage the chain.

Scraper Blade Replacement
Opener blade inside scrapers are spring loaded
and require no adjustment. To replace the
scraper blades, remove rear lock nut and slide
both blades from stem. Assemble with new
blades and replace onto stem being careful not to
overtighten lock nut.
NOTE: Do not over tighten lock nut. Be sure
scapers move freely. Failure to do so
will result in damage to scrapers and
proper operation of scrapers.
Lubrication, Maintenance,
and Service
Proper maintenance will extend the life of your
drill and give you years of excellent performance.
Refer to the repair part drawings and the illustra-
tions below for lubrication requirements. Use a
high quality grease in pivot points and bearings.
On greaseable sealed bearings, be careful not to
over-grease and destroy the dirt seal. Pay atten-
tion to recommended intervals. Oil chains with a
chain lube. A light penetrating oil or liquid graph-
ite should be used on seed cups initially and at
the end of each season. Clean cups with air
pressure or vacuum before applying penetrating
oil.
