Acremeter Installation
Refer to Figure 44
The acremeter
is supplied from the factory in a sepa-
rate carton, to minimize risk of shipping damage. It is
installed on the left end of the center main drive shaft.
Screw the threaded end of the meter into the
1
⁄

-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
readings.
