Corn Planter Showdown Study - Seed Size

The Story: The "Why" Beck's Tested This Every spring, Beck's gets the question: "Is this seed too big (or too small) for my planter to handle?" There is a long-standing debate over whether kernel shape and size affect singulation and, ultimately, your bottom line. Beck's put three of the industry's top planters to the test using Small Plateless and Large Round seeds to see if modern technology can maintain precision—and profit—regardless of what's in the bag. Key Observations Large Rounds Swiped the 2025 Lead: Across all three planter brands, large rounds consistently out-yielded small plateless seeds. The winning John Deere setup saw an 8.1 Bu./A. advantage with large rounds, proving that "difficult" seed shapes aren't a hurdle for modern meters.

Singulation Woes are a Thing of the Past: All three machines—John Deere, Case IH, and Fendt—maintained exceptional singulation, ranging from 96.1% to 99.2% . This confirms that you don't need to fear skips or doubles just because your seed size changes.

Closing Wheels: The

Secret to Emergence: The John Deere 1795 ExactEmerge™ was Beck's 2025 Champion. A key differentiator was its Yetter Poly Twister closing wheels , which provided a massive emergence advantage when a post-planting crust formed in the field.

Speed of Emergence Equals Bushels: Yield results followed 24-hour emergence data almost perfectly. The faster and more uniformly the crop came out of the ground, the higher the final yield. Uniformity is the true driver of ROI. 2025 Results 2025 Planter Showdown (Small Plateless vs. Large Rounds) - 24-Hour Emergence 2025 Planter Showdown (Small Plateless vs. Large Rounds) - Singulation 2025 Planter Showdown (Small Plateless vs. Large Rounds) - Acceptable

Spacing FAQs Q: Do I need to buy special plates or spend hours calibrating for large rounds? A: No. Beck's singulation data (96.1%+) shows that modern vacuum meters handle Large Rounds and Small Plateless seeds with high precision using standard setups. The machine technology has largely eliminated the need to "micromanage" for seed size. Q: Why did Large Rounds yield so much better this year? A: It wasn't necessarily the seed's genetics; it was the environment. In 2025, Beck's had post-planting crusting. The large rounds, combined with the John Deere's Yetter Poly Twister closing wheels, provided the "push" and soil-to-seed contact needed to break through that crust for better emergence. Q: Is the John Deere the only "right" choice for my farm? A: While the John Deere was the 2025 Champion in this test, all three planters showed they could maintain high singulation. The takeaway is to focus on your closing wheel setup and emergence uniformity . If your current planter struggles with crusting, an upgrade to your closing system might be a more cost-effective move than a new planter.
