Germinator® Closing Wheels

Our Story

The Germinator® Closing wheel is an innovative and modern closing wheel that has replaced the traditional and outdated rubber wheels. The Germinator® closing wheel is useful in promoting the successful and consistent germination as well as the emergence of the seed. It is made out of premium-grade steel which is helpful in reducing the risk of sidewall compaction. Utilize down-pressure as you have in the past. You may abe able to lighten it slightly (monitor results if making changes). It is suitable in all types of soil and tillage conditions including heavy soil with no-till conditions.

Recently a Midwest company conducting high-quality practical agricultural research reported that using a superior performing closing wheels such as Germinator® closing wheels was the most cost-effective solution with the quickest most immediate rate of return, for enhancing corn or soybean production and profitability. Their research showed, closing wheels such as Germinator® could increase corn production as much as 5.1 bushels per acre and soybean production 2.5 bushels per acre.

Over the last two years multiple on-farm tests have been conducted comparing the Germinator® closing wheel with its patent pending “inner-rim-shoulder-firmer” to competitors such as Furrow Cruiser and Twister. In every challenge, Germinator® showed the best success at closing the furrow, providing high quality seed-to-soil contact, even emergence; closing down the competition. Germinator® creates a vein of firm soil encasing the seed in perfect soil contact and enhancing the soil’s ability to wick moisture to nourish and germinate the seed.

“In the spring of 2022 two rows of nylon 6 Germinator® closing wheels were compared with Copperhead FurrowCruisers. In the initial 20 acres the nylon six wheels were experiencing a slight soil buildup which had no effect on their performance. This may be the result of semi marginal planting conditions and the manufacture suggested that they may have just needed a little polishing. When I dug behind both systems it was easy to see that the Germinators® were providing better seed-to-soil contact when compared to the Copperheads. With excellent early-season growing conditions providing around a 99% emergence with both systems it was difficult for either product to gain an advantage. With the excellent seed-to-soil contact Germinator® closing wheels generated (a trait they are known for), Germinators® would be one of my top picks out of the closing wheels and systems I have tested over the years.“
