General Information

These instructions include both operation and installation

of an Electronic Acremeter.

Installation

• If installation is necessary, order the appropriate kit

(see “Acremeter Kits”, page 29 through page 33).

• Consult your Great Plains dealer for speciﬁc ordering

information.

• Each acremeter upgrades one drill.

• Installation instructions start at “Acremeter Installa-

tion” on page 13.

Programming the Acremeter

• If your drill was equipped with this acremeter from

production, it will have been supplied already pro-

grammed.

• If you ordered your acremeter and install it yourself, it

will need to be programmed.

• If your new Great Plains acremeter is not prepro-

grammed to your drill, see “Acremeter Operations”

on page 2 of this manual.

Reference Information

• Find “Calibration For All Drill Models”on page 4.

• FInd “Drill Width Charts” on pages 7 and 8.

Tools Required

• basic hand tools.

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.

Great Plains Mfg., Inc. 2 Electronic Acremeter Acremeter Operations 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.
PAGE 3
Great Plains Mfg., Inc. Installation Instructions 3 Field Acres Refer to Figure 3 Press the button until the “FIELD” LED is lit. The digits indicate the acres covered since the field acre counter was last cleared to zero. To clear the field acre count, depress the UP and DOWN buttons for 2 seconds. Note: If a passcode is set, it must be entered to clear the total acre count. Field acres count in tenths of an acre up to 9999.9 acres.
PAGE 4
Great Plains Mfg., Inc. 4 Electronic Acremeter Pulses per 400 Feet of Travel Press the button 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.
PAGE 5
Great Plains Mfg., Inc. Installation Instructions 5 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 travelb may be entered. Run the test with the drill unfolded, and the openers raised.
PAGE 6
Great Plains Mfg., Inc. 6 Electronic Acremeter Width To correctly calculate acres planted, the acremeter needs the swath width of the drill. Note: If a passcode has been set, it must be entered to adjust WIDTH. Refer to Figure 7 Press the button until the “WIDTH” LED is lit. The number displayed is the swath width of your implement in feet (the span between end row units, plus one row unit spacing). To adjust the width, press the UP and DOWN buttons. The width can be adjusted from .1 to 99.

Great Plains Mfg., Inc. Installation Instructions 9 Passcode The “P-WORD” function allows you to protect: - the total acre count, - pulses per 400 feet and - width settings with a 4-digit passcode. This prevents accidental and malicious changes to those settings. As provided by the factory, the passcode feature is disabled, and you can modify those function values at any time. Press the button until the “P-WORD” LED is lit.
PAGE 10
Great Plains Mfg., Inc. 10 Electronic Acremeter Changing the Passcode To change an existing passcode, first enter the existing password as described in ““Using a Passcode””. Refer to Figure 10 While still in the P-WORD function display, select a new passcode using the UP and DOWN buttons. Press and hold the button until the “SEt” (setting password) appears in the display. Release the button. The number in the display is your new password. Be sure to record it.
PAGE 11
Great Plains Mfg., Inc. Installation Instructions 11 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).
PAGE 12
Great Plains Mfg., Inc. 12 Electronic Acremeter 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.

Great Plains Mfg., Inc. Installation Instructions 13 Acremeter Installation Prepare Drill Note: The following examples and instructions are for the 2S-2600. Use the instructions as a guide while referring to the illustration for your specific drill’s acremeter placement starting at “Acremeter Diagrams” on page 16 through page 28. The following installation instructions for installing the sensor, actuator and meter also use the 2S-2600 for the example and assembly steps.

Great Plains Mfg., Inc. Installation Instructions 15 Install Actuator Refer to Figure 15 (this example depicts the 2S-2600) 8. Orient the actuator 30 so that the snap tabs cannot entangle debris during rotation (which is top-of-shaftforward for the enumerated drill models on page 1). Note: The acremeter counts rotations of the ground drive shaft, this is field travelled acres not field planted acres. 9.
