Programming the Acremeter
•If your drill was equipped with this acremeter from
production, it will have been supplied already programmed.
•If you ordered your acremeter and install it yourself, it
will need to be programmed.
•If your new Great Plains acremeter is not preprogrammed to your drill, see “Acremeter Operations”
on page 2 of this manual.
a. The electronic acremeter is compatible with all drills having a main or transfer 7/8 hex drive shaft on any section of the drill. The shaft must
be before any Drive Type, gearbox, lower, range, transmission or upper variable sprockets, and have only fixed sprockets and chains
between the drive wheel and the shaft.
Reference Information
•Find “Calibration For All Drill Models”on page 4.
A battery-operated electronic acre counter is supplied
with the drill. The display module for the system is
normally on the front face of the main toolbar near the
left gauge wheel.
The acremeter calculates and displays the field acres
and total acres accumulated.
The meter counts rotations of the main ground drive
shaft before the clutch. The meter tallies all movements
with the drill unfolded, whether planting or not.
The counter operates in one of two modes
•Insleep mode, the displayis blank, and the counter
is accumulating acres. Sleep mode is entered if a
button is not pressed for 20 seconds. If a passcode is
set, it must be re-entered to change protected function
values.
•Inentry mode, the display is on, and the operator can
enter values. To access entry mode, press the
button. If you continue to press thebutton, the
acre counter cycles through the available functions.
The LED light above the functions indicates which
function is selected.
Values are entered by pressing the UP and
DOWN arrow buttons. Holding a button
automatically increments that value. Long holds
increment faster than short holds. Pressing both
buttons simultaneously is used to reset some values
to 0.
•Tochange modes press and hold all 3 switches at
the same time. When pressed, the current mode will
scroll across the screen. “U” is for USA units, “E” is for
European (metric) units. When you have held all
3 switches for 5 seconds the mode will change.
This means you can check the mode at any time by
pressing the 3 keys and releasing them before
5 seconds has passed without changing anything.
Note: When you change modes, all the defaults are
4
reset to factory values so these will need to be set
properly for the machine. Also area accumulated
in one mode is not converted. It is reset to 0.

Pulses per 400 Feet of Travel
Press thebutton until the “PULSES” LED is lit. The
number in the display indicates how many pulses are
generated for every 400 feet (122 meters in “E” mode)
driven.
Note: If a passcode is set, it must be entered to adjust
the pulses per 400 feet (122 meters) of travel.
There are two methods to enter the pulses: known pulse
value and calibrating pulses per 400 feet (122 meters) of
travel.
Known Pulses Values
Refer to Figure 5
1.If you know the number, select it using the UP and
DOWN buttons. When you press thebutton, the
controller accepts the number in the display as the
new pulses per 400 feet (122 meters).
EXAMPLE:

Calibrating Pulses per 400 Feet of Travel
Note: Calibration is not recommended for the 2S-2600,
3S-3000, 3S-4000, or 3S-5000. Any value other
than 17 pulses per 400 feet results in reduced
accuracy of area measurement.
Refer to Figure 6
The acremeter can count pulses, and if the distance
driven is known, the pulses per 400 feet of travelbmay be
entered. Run the test with the drill unfolded, and the
openers raised.
Pulses Per Mile
Note: If you have documentation yet from a past design
of acremeter listing the pulse value stated as
pulses per mile, divide that value by 13.2 to arrive
at a new number. (5280 feet per mile/400 ft =
13.2). If you get a fraction round up to the next full
digit for the best accuracy.
To calibrate the pulses per 400 feet of travel, press and
hold the UP and DOWN buttons until “0” appears in the
PULSES display. The acre counter is now ready to count
shaft rotations.
Enter the tractor cab and drive 400 feet.
Press thebutton to wake up the acre counter. The
“PULSES” LED will again blink. The number displayed is
the pulses per 400 feet. Press thebutton to accept the
setting. The “PULSES” LED will stop blinking and remain
on.

Battery Replacement
The battery operated acre counter uses 3 AA-size
alkaline batteries. Although the batteries typically last
between 5 and 10 years, they should be inspected
annually, as low batteries can leak corrosive chemicals,
and damage the electronic acremeter.
If battery replacement is needed, the acre counter
displays “LobAt” (low battery).
For battery inspection or replacement, dismount the acre
counter from the implement and remove the 4 screws on
the back of the case. This will separate the housing from
the rear plate. Replace the batteries with 3 high quality
AA alkaline batteries.
Note: The module is dust and splash resistant, but under
no circumstance should it be submerged in any
conductive, corrosive or flammable liquid.

Reference Information
Accuracy Considerations
Many factors can affect the accuracy of your electronic
acremeter:
•Tire Size and Tire Pressure
•Seeding Overlap
The area reported by the meter will be higher than
the actual field area if passes overlap.
•Soil Conditions
The meter configuration was programmed for nominal
tire slippage. Extreme conditions, wet or muddy
conditions, min-till/no-till conditions and some native
grass conditions may change wheel slippage,
resulting in slightly inaccurate area tallies.
Display
Liquid Crystal Displays (LCDs) do not function optimally
in extremely cold conditions (conditions colder than you
are likely to be planting in). If the display is blank, hard to
read, or sluggish, and the weather is near freezing, the
LCD is likely responding to the temperature.
The battery, rotational sensor and computer electronics
are still operating, however, and read-out will be possible
once the meter warms up. Do not use direct application
of hot air, fluids or metal to warm up the meter, or you
may damage it.
