Opener-Frame Clearance
Refer to Figure 43
When fully raised, top of opener mounts should clear
bottom of drill frame tube by at least 1 ⁄
2
inch (12.7mm).
To adjust opener frames so all openers have the same
clearance, loosen jam nut
on opener lift cylinders and
turn adjustment nut. When openers are at the correct
height, retighten jam nut. Repeat at each opener lift cyl-
inder if necessary.

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 ⁄
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
readings.
