All About Ninja Seed Flaps

Exapta’s Ninja flexible seed bounce flap keeps more seeds in the furrow, and is less prone to breakage in the field (less brittle) as compared to OEM or other aftermarket flaps.

Keep Seeds in the Furrow

Exapta’s unique forward bend puts more seeds in the bottom of the furrow.

Close the Gap

Straight, stiff plastic seed flabs (‘tabs’) such as OEM and competitors leave a gap through which seeds can escape.

Ninja: Down, Forward, No Gap

Our Ninja flap has a 20-degree forward bend to help close the gap, thus keeping more seeds in the furrow. The flexibility of the Ninja prevents it from riding up (lifting) on the sidewall like a stiff flap would, which makes the gap bigger on those flaps.

The flap, or tab on the seed boot is what keeps seeds from bouncing out of the furrow, and this is even more critical on air drills, since the air stream is also trying to escape and may carry seeds along with it. However, JD & aftermarket flap suppliers use a straight flap, made from materials that are too brittle—often snapping off in the field. The issue with straight flaps is that it leaves a triangular gap for seeds to escape, and this gap gets larger when the straight flaps bend upward during use, due to riding on the sidewall.

Our Ninja flap has a 20-degree forward bend to help close this gap, thus keeping more seeds in the furrow. The forward bend helps deflect seeds downward into the furrow bottom before dust and chunks of sidewall fall in ahead of the seed. The flexible material and tapered end prevent the Ninja flap from riding on the sidewall. The result is better seed placement. Ninjas also shed mud better than OEM and competitor tabs, and are proven to have superior wear characteristics — our Ninjas will last at least 5 times longer than OEM or competitors! (indeed, we don’t know of anyone who has actually worn any out!)

“The Ninja seed tabs have made a huge difference to our seed placement and accuracy—before, we had a lot of seed near and on top of the soil. Also finding we don’t need to run the discs as deep to achieve optimum seed depth and placement.”

Tocumwal, NSW, Australia, Exapta customer since 2015 (Ninjas on JD 1895 drill)
“The Ninjas hardly wore at all. They fit down in the furrow so much better than other flaps on the market. I really appreciate what you guys are doing for the farmer.”

“We’ve now got 10,000 acres on our Ninja flaps, and they look fine yet—very little wear. They’ll easily go another season, unlike the [competitor aftermarket] tabs that needed replacing every season [5,000 acres].”
Darin Brunk & Joe Swanson
Windom, KS, Exapta customers since ’99 (Ninjas on 40-ft JD 1890)
“The Ninja seed flaps are great. I put half Ninjas and half [competitor’s] on to start the 2015 season. Probably did about 3,500+ acres this year with 30′ drill. The [competitor’s] get pretty worn after a couple hundred acres, but I left them on all year for the PITA factor. Yours [Ninjas] are not near replacement yet.”
Jordan Reimnitz
Armour, SD, Customer since 2009 (JD 1860 drill w/ 90 series boots)
