Acremeter Operation
An electronic acremeter or hectare meter is standard on
new drills. It is available as an accessory (page 34) for
drills manufactured prior to October 2005, or if alternate
units of measure are desired.
Refer to Figure 7 and Figure 8
The acremeter counts shaft rotations whenever the shaft
is rotating - this is with the drill lowered and in motion or
during crank operation. The meter is programmed to
display rotations as acres or hectares, when using all
rows, factory-specified tires and tire inflations. See the
Electronic Acremeter Manual 152-314M.
Normal Operating Sequence
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. The smaller number in the lower left
corner is the number of revolutions per acre (or
hectare) for which the meter was programmed. If the
display is blank, see “Dormant Display” below.
Note: The acremeter counts rotations during drill
calibration (and if so, can be useful for calibration,
although the meter must be on, or moved to, the
shaft being cranked).
2. Lower drill and plant. The 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 drive wheel stops, 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
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
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 logo
spots on the lower region of the display. Be careful
not to scratch the window.
Note: Unusual conditions and/or non-standard row
spacings can cause the acremeter tally to vary
from actual acres planted.
