Install Discs
Refer to Figure 25 (which depicts the left arm, folded)
If the discs are already installed, continue at “Set Initial
Extension”.
If the markers are being installed as part of export
pre-delivery, you may wish to defer disc installation until
all above-frame components are installed. This
minimizes sharp object hazards during work on top of
the frame.
Start with the left side of the planter. The 113-563S disc
assemblies
use identical parts, but are normally
pre-assembled in mirror-image for left and right use.
112. Select one new:
113-563S MARKER DISC & HUB ASSEMBLY
Choose the assembly that matches the image in
Figure 25 for the left arm, or matches the image in
Figure 26 for the right arm.
113. Select two new:
804-017C WASHER FLAT 1/2 USS PLT
and four sets new:
802-039C HHCS 1/2-13X3 GR5
803-019C NUT LOCK 1/2-13 PLT
114. If the arm is folded, orient the disc assembly on
top of the arm tube .
If the arm is unfolded, orient the assembly on the
bottom of the arm tube.
115. Attach the arm to the tube with a bolt and lock
nut at the outer holes. Tighten only to snug. The
weldment must pivot for field adjustment.
116. Place a washer on the other bolt . Insert it
through the assembly adjustment slot, then the arm
tube. Add another washer
and add a lock
nut . Set the adjustment angle to centered in the
curved slot. Tighten nut. Final disc angle
adjustments are made based on field conditions.
Refer to Figure 26 (which depicts the right arm, folded)
117. Repeat step 112 through step 116 for the right arm.

Wear gloves when working with or near the marker disc. The
edges are sharp. Lift the assembly at the hub or adjustment
mount. The disc rotates freely, and it is easy to lose a grip.
A falling disc could inflict serious injury.
