 Topic: AC 1 row Planter - Sprockets
Posted: 01 Sep 2010 at 11:48am |
I have a AC 1 row planter that was made from a larger planter. I have a 28, 24 and 20 tooth sprockets. This year I used the 24 tooth with a 24 cell plate to plant sweet corn. Spacing was too far apart, 15 inchs, prefer 9 inches, I will be getting a 16 cell plate from Lincoln Ag Products, but still need help with the sprocket set-up. Do not have a manual. Any help with the setup would be appreciated. The circumference of the drive wheel is 60 inches.

Looks like you used a 20 driver and 24 driven. and you got 15 inch spacing or 8 plants per 10 feet of row. So that was with a ratio of 1:1.2 or .8333:1.
For 9" spacing you wish 13.3333 per 10 feet and that would take a ratio increase of 13.333/8 times .8333 or a ratio of 1.389:1. If you use a 28 driver and a 20 driven you get a drive ratio of 1.4:1 and that will get you 13.44 plants per 10 feet or a plant spacing of 8.92".

Thanks Gerald J. Just so I am clear, the driver sprocket is on the back drive wheel and the driven is controling the seed drop, correct? Again, thank you

Does a 16 cell or 24 cell plate drop seed closer?

24 cell if the chain sprockets are the same. The rate is the same if you turn the 16 cell 50% faster than the 24 cell. Likely big seed won't fit the 24 cell, and two small seed might fit the 16 cell which affects your choice of plate and seed.
