4-26 DRIVE SHAFT – COUPLER ALIGNMENT
The center box seed shaft is driven from the
drive wheel on the right wing. The drive shaft con-
nects via a coupler when the grain drill is unfolded.
The drive shaft coupler should be in alignment
when the drill is unfolded and in the planting posi-
tion.
4-26.1 To align the coupler, loosen the adjust-
ment bolts A, B, and C (See Figure 4-34).
4-26.2 Loosen any setcrews at the seed trans-
mission bearings on the center section. The
center frame drive shaft should now be free
to slide side-to-side.
4-26.3 Unfold the drill and lower the openers to
planting position.
4-26.4 Rotate and align the male and female
couplers teeth and slide the center drive
shaft to the right until the teeth fully engage.
