Acremeter Operation
The acremeter, located on the drill clutch shaft, counts
shaft rotations whenever the shaft is rotating - this is with
the drill lowered and in motion or during calibration crank
operation. The meter is programmed to display rotations
as acres or hectares
1
, when using all rows, factory-spec-
ified tires and tire inflations.
Note: Unusual conditions and/or non-standard row spac-
ings can cause the acremeter tally to vary from ac-
tual acres planted.
Normal Operating Sequence
Note: The acremeter counts rotations during drill calibra-
tion (and if so, can be useful for calibration).
1. Record the acremeter reading at the start of planting
(and after calibration). The large “12345.6” format
display is the grand total area since meter installa-
tion. The smaller number in the lower left corner is
the number of revolutions per acre for which the
meter was factory-programmed. If the display is
blank, see “Dormant Display” below.
2. Lower drill and plant. Acremeter counts shaft rota-
tions, calculates acres or hectares, and adds to the
running grand total.
3. During planting (drill lowered and moving forward),
the display blanks (goes dormant), but area tally con-
tinues.
4. When raised for turns, obstructions and transport,
the clutch disengages, the shaft stops, and the meter
counts no additional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display acti-
vates after 30 to 60 seconds, and remains visible for
30 to 45 minutes.
6. At the completion of planting, record the final reading
or the grand total. If the display goes dormant before
you can read it, see “Dormant Display”.
7. Subtract the reading at Step 1 from the reading at
Step 6 for the total planted in the present session.
Dormant Display
Refer to Figure 14
To conserve power, the LCD display blanks itself most of
the time. If you need to read the display after it has
“timed out” and gone dormant:
• use the calibration crank to turn the jackshaft once, or
• gently tap or wave a magnet at either of the Great
Plains logo spots on the lower region of the display.
Be careful not to scratch the window.
