Refer to Figure 8-2:
Native Grass Seed Main Drive Chain (#1)
1.
Check take-up of chain (#1). If needed, loosen
1/2"-13 nuts on bolts (#2 & #3) and adjust
sprocket (#1) by rotating bearing mount (#4) to adjust
chain take-up. Tighten nuts on bolts (#2 & #3) to the
correct torque.
2.
Check chain (#1) to ensure it is not over-tightened.
Native Grass Seed Gearbox Drive Chain (#5)
1.
Check take-up of chain (#5). If needed, loosen
1/2"-13 nut (#6) and adjust sprockets (#7 & #8) to
adjust chain take-up. Tighten nut (#6) to the correct
torque.
2.
Check chain (#5) to ensure it is not over-tightened.
Native Grass Seed Cup Drive Chain (#10)
1.
Check take-up of chain (#10). If needed, loosen
1/2"-13 nut (#11) and adjust sprockets (#12 & #13) to
adjust chain take-up. Tighten nut (#11) to the correct
torque.
2.
Recheck chain (#10) to ensure it is not over-
tightened.
Native Grass Seed Agitator Drive Chain (#14)
1.
Check take-up of chain (#14). If needed, loosen
5/16"-18 lock nuts (#15) and adjust bearing (#16)
vertically to adjust chain take-up. Tighten lock nuts
(#15) to the correct torque.
2.
Check chain (#14) to ensure it is not over-tightened.

Grass Seed Reduction Drive Chains
Refer to Figure 8-3:
1.
Check take-up of chain (#1). If needed, loosen
3/8"-16 hex flange nut (#4) and adjust sprocket (#5)
in bearing mount (#6) to adjust chain take-up.
Tighten hex flange nut (#4) to the correct torque for a
grade 5 bolt.
2.
Check chain (#1) to ensure it is not over-tightened.
3.
Check wear in chain (#2). Replace chain (#2) if it is
worn and does not engage properly with the sprocket
teeth.
4.
Check take-up of chain (#3). If needed, loosen
5/16"-18 lock nuts (#8) and adjust bearing (#7)
vertically to adjust chain take-up. Tighten lock
nuts (#8) to the correct torque.
5.
Check chain (#3) to ensure it is not over-tightened.
