ASSEMBLY
5 and 7 Shank Manual Coulter
Assemble the Spring Bracket Assemblies to the frame.
(Two on 5-shank models; four on 7-shank models.) Using
5/8-11 x 3-3/4” bolts, lock washers and nuts. Note that
they are to be assembled to the frame members that
have holes for the coulter gang bearing castings. See
Figures 2-5 and 2-6. Locate the center of the spring
brackets 19-3/4” from the front of the frame. See
Figure 2-3.
Next, roll the Coulter Gang Assembly/Assemblies under
the frame. On 7 shank models roll the gang with the most
coulters under the left side of the machine; slotted nut to
the outside. Roll the other gang under the right side of the
machine, slotted nut to the inside.
Then lower the machine and install the axle bearings to
the coulter gangs and to the frame. See Figures 2-5 and
2-6. Use the 5/8-11 x 10-1/2” long bolts, lock washers
and nuts. Next, attach the spring rods to the Coulter
Gang Assembly/Assemblies with the 3/4” x 2 1/2” long
clevis pins, flat washers and 1/8” x 1-1/4” cotter pins.
NOTE
Use the upper most hole in the spring rod straps for
normal conditions. Where more pressure on coulters is
desired, change to different setting accordingly.
