Note: Check gang angle adjustment when machine is new
and annually after, as wear may occur.
20. With front gang adjusting cylinders in the full retract
position the gang bar should be 1/8” from tubes .
21. If gang bar is not 1/8” from tubes loosen allen
screw on clevis on rod end of cylinder (there are two
flat spots on rod to get wrench on to adjust) and shorten
cylinder rod
by turning cylinder rod to bring gang bar
closer and lengthen clevis to get cylinder to retract all
the way.

rocker between two turnbuckles and the other has just
one turnbuckle between the front and rear gang bars.
They both adjust the same way.
23. When the front gang adjusting cylinders , have been
adjusted and are in the full retract position the rear gang
bar
should be parallel to back frame tube.

remove pin from turnbuckle end and shorten turn-
buckle end by turning clevis to bring gang bar closer and
lengthen clevis to get gang bar to retract all the way.
25. Re-install pin when adjustment is made.
