Opener-Frame Clearance
Refer to Figure 38
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 cylin-
der if necessary.

Acremeter Installation
Refer to Figure 39
The acremeter
is supplied from the factory in a sepa-
rate carton, to minimize risk of shipping damage. Check
to see if it has already been installed by your dealer. It is
located on the left end of the center main drive shaft.
If not already installed, screw the threaded end of the
meter into the
1 ⁄
2
-20 tapped hole in the left end of cen-
ter 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 end 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.
