Operating the Machine REAR GANG SIDE ADJUSTMENT The rear gang of the disk harrow can be adjusted from side to side. If the rear gang is moved to the left, it increases the amount of soil being thrown into the furrow. If the rear gang is shifted to the right, it will decrease the amount of soil being thrown into the furrow. In order to shift the rear gang to the right or left, loosen the gang carrier mounting bolts on the gang carrier brackets that are slotted. Now remove the bolts that are in the brackets without slots. Then reposition the gang carrier on the frame by pulling the harrow forward or backward while the disk blades are resting on the ground. This action will cause the gang carrier to shift to the right or left as desired. Finally, align bolt holes and replace bolts. Be sure to torque all bolts securely.
