2. Insert the Nut Bar lengthwise into the Main Arm as
shown in Photo 5. Continue to slide the bar in until the
two tapped holes in the Nut Bar are aligned with the
two holes at the end of the Main Arm. When the holes
are aligned, and the Extension Arm is at the length you
want, then secure the arms together with two 1/4”-20 x
1/2” long thumbscrews (see Photo 6 inset) turning
them until they’re tight.
Note: To adjust the Marker Extension Arm in or out to suit
a row width for your application, simply unthread the
thumbscrews one full turn, then adjust the arm length
before retightening the thumbscrews. Fully extended, the
Row Marker is 49-3/4” long; fully retracted, 28”.
Step 4: Attach Main Marker Arm
to the Main Support
The Main Marker Arm connects to the Yoke at the top of
the Main Support with a quick-release pin.
1. Align the sleeve located at the end of the Main Arm
between either the top set or bottom set of holes on the
yoke sides. See Photo 7.
2. Once the sleeve is lined up, insert the quick release pin
(Photo 8, Inset). At this point, the Main Arm rests on
the Stop Bar and points straight back from the rear of
the tiller.
IMPORTANT: The top and bottom sets of holes on the yoke
sides allow the marker arm to rest on the Stop Bar at the
proper angle regardless of whether the Extension Arm is
fully extended or retracted.
When the extension arm is
more than 50% extended, use the bottom set of holes,
otherwise use the top set of holes.
3. Pivot the Marker Arm from its “straight back” position a
full
90
°
to either the right or the left in order to get the
Marker Arm to point out to the side of the Tiller.
Whether you decide to pivot right or left, just
be sure
the points of the Marker Blade face back toward the
operator after the arm has been pivoted
. See Photo 9
and Photo 10 for the correct in-use position.
