Acremeter Operation
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.
Note: Unusual conditions and/or non-standard row
spacings can cause the acremeter tally to vary from
actual acres planted.
Normal Operating Sequence
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).
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. If the display is blank, see “
” below.
2. Lower drill and plant. 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.
Disc Blade Adjustments
(as blades wear)
(page 34)
As blades wear, the diameter of the discs, and their
contact gap, changes. Seeding depth will also
change (or become irregular), unless adjustments
are made to blade spacing and the T-handle setting.
Generally, the blades need to be replaced com-
pletely before coulter height adjustments would be
needed.
