MAINTENANCE & ADJUSTMENT
Acre Meter Troubleshooting
IMPORTANT
Acre Meter is dust and splash resistant, under no
circumstances should this unit be submerged in any
conductive, corrosive, or flammable liquid. At no
time use high pressure water or air to clean it, as this
can damage the unit.
Figure 4-8: Acre Meter
NOTE
The ground wire is for static discharge protection and has
no effect on the ability of the sensor to function properly
under normal conditions.
The battery operated Acre Meter uses 3 AA batteries.
The Acre Meter will display "LObat" when the batteries
require replacement. Remove the Acre Meter from the
implement and then the 4 Screws on the back of the
case. Separate the housing from the rear plate. Replace
with 3 quality AA batteries.
Acre Meter does not count pulses during calibration
or does not count acres during operation.
1. Check the position of the Magnet Wheel Assembly
and Pick-up Switch against the set-up instructions in
this manual. See Figure 2-22.
2. Verify that the magnet in the Magnet Wheel
Assembly has not come out.
3. Place the Acre Meter display in "Calibrate" mode by
pressing the *(FUNC) key until the P-Word indictor is
lit and then press the up/down arrow keys until the
display shows 0 and the LED is blinking. Break the
connection between the display and the Pick-up
Switch and short between pins A and B on the
display harness connector. You should see the
display increment +1 with each contact of the
connector terminals.

4. If step 3 works then wave a magnet in front of the
Pick-up Switch face with it re-connected to the
display and see if the display increments up. If not,
put an ohm meter or continuity tester on the contacts
of the Pick-up Switch harness and place a magnet in
front of the Pick-up Switch face. The Pick-up Switch
should show continuity or near 0 ohms resistance.
Acre Meter can not change the width or pulse count
settings or clear the field and total acres.
1. Check to see if a password needs to be entered by
pressing the *(FUNC) key until the P-Word indicator
LED is lit. If "dIS" is displayed (password disabled) no
password is set.
2. If "Ent" is displayed a password must be entered to
change the settings or the password must be
disabled as instructed in the setup section of this
manual.
Storage
1. The service life of the Seeder will be extended by
proper off-season storage practices. Prior to storing
the unit, complete the following procedures:
a. Completely clean the unit, blow all seed out of
meters.
b. Inspect the machine for worn or defective parts.
Replace as needed.
c. Repaint all areas where the original paint is worn
off.
d. Apply a light coating of oil or grease to exposed
cylinder rods to prevent them from rusting.
e. Lubricate each point of the machine as stated in
"Lubrication" on page 4-3.
2. Store the unit in a shed or under a tarpaulin to protect
it from the weather. The ground tools and tires
should rest on boards, or some other object, to keep
them out of the soil.
3. 3Pt Hitch Models, raise track removers, lower
Parking Stands, and insert Parking Pin before
unhitching from tractor.
4. Pull Type Models, raise the machine and install
Transport Locks. Lower Drawbar Jack.
a. Relieve Hydraulic Pressure in hoses after locks
are installed.
b. Block wheels before unhitching from tractor.
