sprockets located above and behind the Drive Type
sprocket.
Refer to the Fertilizer Rate Charts (pages 19, 20, 31 and

between shafts).
To change the transmission setting:

2. Remove pin from vertical storage tower , and
retrieve new sprocket(s) required. Return other to the
storage tree, but leave pin off.
3. Remove lynch pins from Driver and/or Driven
sprocket shaft to be changed, and remove
sprocket(s).
4. Place correct Driver and Driven sprockets on their
respective shafts.
5. Store removed sprockets on storage tree.
6. Re-install all pins.
7. Reinstall chain and engage idlers, allowing 1 ⁄
