Mail us a seed sample and we’ll match it to the right plate before you order.

How to send a sample

Massey Ferguson owners: our 4 Massey Ferguson plates are for planters that use flat-drop cells (fully enclosed, roughly 8¼” overall diameter). If your MF planter uses edge-drop plates, ours will not fit. Check your planter’s plate style before ordering. See Seed Sizing Guide: Massey Ferguson.

COMMON QUESTIONS

Check your seed bag for a plate size recommendation first. If there isn’t one, see our full Seed Sizing Guide for how to measure your seed against a plate, or just send us a small sample.

  • John Deere plates (part numbers starting with B) are 6-15/16″ overall diameter. They fit the John Deere 71 and similar JD gravity-fed plate planters, the Yetter 71 Series, and Allis Chalmers gravity-fed planters when paired with our AC-Adaptor.
  • International plates (part numbers starting with C) are 7-5/8″ overall diameter. They fit the IHC 56 and similar IHC gravity-fed planters, as well as 1968-and-later Case planters.

A 16-cell plate plants about 1/3 less seed than a 24-cell plate. 24-cell is the more common choice. Seed spacing also depends on your planter’s sprocket settings, so check your Operator’s Manual.

Not with every plate — but Sunflower and Sorghum single-drop plates are thinner than a standard corn plate and need a specific filler ring to fit tight in the planter bottom. Filler ring thickness is matched to a specific plate, so using the wrong one will throw off your seed drop even with the correct plate installed.

Yes. Send 10–20 seeds, including the largest in the sample, wrapped so they won’t get crushed by postage machines (a bubble mailer works well). Include your email address and the type of planter you have, and we’ll typically email a recommendation the same day we receive the seed.
