Calibration
Use the formulas below to determine your imple-
ment calibration factor or refer to the predeter-
mined factors listed when using CrustBuster
drills.
DT = Distance traveled with one counter shaft rota-
tion (when using two magnets, divide DT by 2).
WW = Working Width of implement (in inches).
WW x DT/2 = Calibration factor
6272640
NOTE: Whenever a gear change is made on the
shaft being monitored, you will need to enter a
new calibration factor.
Entering Calibration Factor
1. Depress ON/C
2. Round off factor to 5 digits
3. Enter factor (remember decimal point)
4. Depress + key
5. Depress = key
6. Depress decimal point (screen display 0)

Sprocket Box Adjustment
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 select seed rate.
A narrow slot width will produce more even
distribution and spacing in the row.
For round seeds, the ideal slot width can be
determined by measuring seed size. To attain
singular file flow of seeds from the wobble slot
seed cup, the slot width should be greater than
one and one half (1 ½) times the average seed
size, but less than two (2) times the average size.
Ideal Slot Width =
Greater than (>) 1½ times seed size
Less than (<) 2 times seed size
To determine average seed size, lay out 20-30
seeds in single file, each seed touching each
other. A short piece of angle iron can help align
the seeds evenly. Measure distance from end to
end with a ruler. Divide that measurement by the
number of seeds to equal the average seed size.
Multiply average seed size times 1½ to find the
minimum width. Multiply average seed size times
2 to find the maximum width. The slot width
should be ideal when set between these values.
Example: 30 seeds measure 9 inches.
9 " divided by 30 seeds = .30"
.30" times 1.5 = .45"
.30 times 2 = .60"
Ideal slot width is greater than .45",less than .60"
Ideal slot width = ½"
Refer to seed chart ½" column as a starting point
for setting final seed rate.
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.
