Closing Upgrade Kit
Complete closing upgrade for planters. Fits most JD, Kinze, AGCO White, and Great Plains planters. Includes 2 Thompson wheels (T2X or T3X: metric or 5/8” sleeve/shroud) 2 wedges, and a medium closing spring.
Sizing Things Up
The bearing from a competitor’s wheel setting inside the Thompson wheel’s housing for its huge bearing. Our bearing features a triple-lip seal, as well as our unique, patented shroud to protect the bearing face from fertilizer and water. We’re so confident in our bearing arrangement, we guarantee it for 5 years.
The Thompson wheel’s high-carbon spokes resist wear and bending for an exceptionally long life.The thinness of the wheel allows it to easily enter the soil, for excellent breakage of the sidewall.
The blunt tip & tapering sides of the spokes further assist in crumbling the sidewall. The tapering sides gradually increase the resistance the spoke encounters while operating in the soil. This limits the depth, as does the overall length of the spoke itself (considerably shorter than some other designs on the market). So you get just the right amount of sidewall shattering, without digging too deep. The thinness is also what prevents mud accumulation on the spokes. It simply has nowhere to gather.
No-till seeding (also known as zero-till) is a relatively new phenomenon, and more effective methods are continually being developed. In the U.S. & Canada, most planters and “no-till” drills are ill-suited to the task from the moment they’re built (they were engineered for tilled seedbeds). For instance, the original smooth closing wheels on all planters and no-till drills can overpack the furrow, especially when soils are damp, causing poor emergence and poor root penetration of the sidewall. Because of the soil structure in no-till, the solid wheel is ineffective at closing the furrow. To avoid the packing problem, as well as the poor furrow closing by smooth closing wheels, several aftermarket companies began offering spoked wheels to replace the original closing wheel.

Toe-Out Wedge Makes Thompson Wheels Even Better.
The toe-out helps all spoked wheels to more actively engage and gather soil from the fractured sidewall and pull it back into the furrow—sort of the reverse of the opener blades prying apart the soil while creating the furrow. It even helps the beveled cast closers (non-spoked).

More on Toe-out Wedges
“We farm clay knobs, sandy loams, and high-organic muck soils, often all on the same day. We tried a number of different closing wheels and found the Thompson wheels performed well across all those conditions. I run them toed-out about 3 degrees.” (Mojos, T-wheels & toe-out wedges on JD 1700-series planter)Chuck Zumbrun
“In wetter conditions, the T-wheels help close up the seed furrow. They help break up the dirt to get better cover over the seed.”Howard G Buffet
“I’ve used the Thompson wheels and toe-out wedges for about five years. I’ve found them to be far superior to any other closing systems I have tried. They’re very versatile in the fact that they don’t wrap in tall cover crops like green cereal rye, and will close in hay sod where the furrow wants to open back up. Thompson wheels also shatter the sidewall, helping to reduce sidewall compaction in less-than-perfect conditions in corn or soybean stubble. They also work well in varying soil and moisture conditions in the same field. I would recommend the Thompson wheels to anyone who wants to improve their soil by using cover crops and no-till.”Chris Broyan
“The Thompson wheels are definitely better than the [competitor spike wheels]. I really like how the Thompsons break up the sidewall. My stand counts are 4 – 6% higher with the Thompson wheels, and with fewer ‘dink’ plants…. I’m concerned that I’ve been using the wrong closing wheels [competitor spike] for the past 10 years.”Tom Cannon
In The News
Almost to the Colorado border, these far western KS no-tillers credit some of their success to good seeding equipment set up—including Exapta’s Thompson wheels on their drill as well as their planter (although we do worry about theT-whls on their planter not being ran with a seed firmer).
