MARKER ADJUSTMENTS
STORAGE SADDLE ADJUSTMENT
When folding the marker for the first time, it may be necessary to move the marker storage saddle, Transport Carrier
Mounting 24’ Drill (#50) into alignment with the 2nd section of the marker arm. Slowly fold the marker(s) and stop when
the marker is just above the storage saddle. Adjust the bracket(s) in or out as needed.
TRANSPORT CARRIER ADJUSTMENT
After centering the storage saddle(s) and folding the marker(s), visually check to see if the height of the transport carrier
is correct. Transport Carrier Mounting 24’ Drill (#45). The 2nd section of the marker should appear parallel with the top
of the drill box. If not, loosen the transport carrier u-bolts (#47) and adjust the carrier up or down.
MARKER CHAIN ADJUSTMENT
There are two basic adjustments needed on the marker chain, especially in new installations. They are interrelated, and
should be done in the following order:
1. Lifting Slack. Start with the marker in the unfolded position. Back the full threaded adjustment bolt Fig. 2 on page 1-
4 (#21) down until the head extends as little as possible. Slowly fold the marker, observing the motion of the disk. If the
marker disk slides across the ground more than about one foot before the chain and linkage lifts it up, the chain is too
slack. Tighten the chain by moving the clevis one or two links at the inboard end of the chain. Recheck by repeating step
1.
If the chain does not have enough slack when the marker is in the unfolded field position, the chain will prevent the end
of the marker from dropping down to follow a depression in the field. Correct this condition by moving the utility clevis
one or two links, giving the chain more slack.
2. Folding Slack. After the adjustments in step one have been completed, fold the marker(s). The full threaded adjust-
ment bolt Fig. 2 on page
1-4 (#21) is provided to take the slack out of the chain while the marker is in the folded position.
Extend this bolt until the slack is out of the chain. Lock the bolt in this position by tightening the nuts on either side of the
upright channel on section 1.
DISK ADJUSTMENTS
The aggressiveness and the mark left by the disk may be changed by two methods:
1. Disk Angle. To change the angle of cut, loosen the two bolts (#41) Fig. 5 on page 1-6, rotate the disk assembly and
retighten.
2. Direction Of Cut. The disk may be mounted to throw dirt either in or out which will give different marks in different soil
conditions. To change the direction of cut:
a. Reverse the blade and depth band by remounting the four lug bolts on the disk hub.
b. Reverse the angle of the assembly by removing the adjustment bolts (#41) Fig. 5 on page 1-6 and turning the
spindle assembly one half turn. Reinstall and tighten all bolts.
