Acremeter Installation
Refer to Figure 99
The acremeter
is factory installed. It is located on the
left end of the left main drive shaft .
If the acremeter has been removed, screw the threaded
end of the meter into the
1 ⁄
2
-20 tapped hole in the left
end of center main drive shaft.
Tighten the threaded end only enough to prevent it from
working loose from normal vibration. In use, there is no
torque or tension that might tend to unscrew it.
The acremeter counts shaft rotations whenever the shaft
is rotating - normally this is only with the drill unfolded,
the opener sub-frame lowered, and the drill in motion.
The meter is geared to display rotations as acres, when
using factory-specified tires and inflations.
Tally field acres by noting the meter reading prior to, and
after planting. Subtract the starting from the ending read-
ings.
See “Acremeter Operation” on page 112.
Acremeter Operation
The acremeter, located on the drill clutch shaft, counts
shaft rotations whenever the shaft is rotating - this is with
the drill lowered and in motion or during calibration crank
operation. The meter is programmed to display rotations
as acres or hectares, when using all rows, factory-speci-
fied 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 counts rotations during drill calibra-
tion (and if so, can be useful for calibration, al-
though the meter must be on, or moved to the shaft
being cranked).
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 cor-
ner is the number of revolutions per acre for which
the meter was factory-programmed. If the display is
blank, see “Dormant Display” below.
2. Lower drill and plant. Acremeter counts shaft rota-
tions, calculates acres or hectares, and adds to the
running grand total.
