Planters J D 71 planter gears

[deere755]

Can anyone tell me how many gears in a full set for a model 71 planter. Mine has 4 per row unit. I would think there should be more then that. I am trying to find something in my owners manual but I think it is missing a few pages. Thanks for any help on this in advance.

There should be a total of 4 sprockets per row unit. 2 mounted in place and 2 more stored in the chain enclosure.

Here's the YETTER #71 manual you can download. It's the same EXACT planter as a Deere 71. Parts are interchangeable. Manual will give you ratios with all possible combinations.
