GANG POSITIONING
1. Mount the tubular gang hangers, Ref. 1, Fig. 2, to the
gangs at the bearing housing using the ½ “ x 3 ½ “ Gr.
5 hex bolts, Ref. 2. Be sure the “lean” of the hanger is
with the concavity of the blade. Lift the entire gang (with
hangers attached) underneath the gang beam until the
top of the hanger is flush against the bottom of the gang
beam. Place the U-bolt, Ref. 3, over the gang beam and
into the tubular gang hanger and tighten loosely. Do not
fully tighten these U-bolts until all gangs are mounted
and properly spaced.
2. Install the rear gangs first since it is easy to hoist the
tongue and lower the rear of the harrow down to the
gangs. Space the rear gangs so that the inside blades
are equal distances from the center of the main frame
and so that the rear edges of the blades at the closest
point are about 2” less than the diameter of the disc blades. For example, 22” blades
would be spaced 20” apart on the rear. See Fig. 3.
3. Space the next gang out so the space between them is the same as all the other
blades.
4. To install the front gangs, you will probably have to adjust the wheel carriage and
lower the tongue, Space the inside front blades so that they just clear each other
(about ¼ “ to ½ “) and are perfectly center under the main frame at maximum gang
angle.
5. When all gangs are in place and properly spaced, tighten all U-bolts.
