Acremeter Operation
The acremeter counts shaft rotations whenever the shaft
is rotating - normally this is only with the drill lowered and
in motion. The meter is programmed to display rotations
as acres or hectares, when using all rows,
factory-specified tires and tire inflations.
Note: Unusual conditions and/or non-standard row spac-
ings can cause the acremeter tally to vary some-
what from actual acres planted.
Normal Operating Sequence
Note: The acremeter may count rotations during drill cal-
ibration (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 planted since meter
installation. If the display is blank, see “Dormant
Display” below.
2. Lower drill and plant. Acremeter counts shaft
rotations, 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
continues.
4. When raised for turns, obstructions and transport,
the drill’s ground drive wheel, contact wheel or clutch
disengages the drive shaft, and the meter counts no
additional (non-planting) rotations.
5. Whenever shaft rotation stops, the LCD display
activates after 30 to 60 seconds, and remains visible
for 30 to 45 minutes.
6. At the completion of planting, record the final reading
of 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 26
To conserve power, the LCD display blanks itself most of
the time.
If you need to read the display after if has “timed out” and
gone dormant, 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.
