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. New ‘z’ series is even tougher, higher-carbon steel than our ‘X’ series — so tough, it’s actually used for armor plating by the military.
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.
“The smooth JD cast wheels won’t close the furrow when it gets hard and dry. But the Thompson wheels will penetrate and close the furrow. Crumbling versus smashing the furrow shut makes a big difference, especially if soils are wet.”
“I’m no-tilling with a JD 1890 in clay-loam soil. I tend to drive a little fast, 6 – 9 mph. The OEM closing wheels were in the air probably 50% of the time. The [competitor spoked wheels] are also heavy and tend also to bounce. I’ve got along best with the Thompsons. I ran all three side-by-side last year , and now have all Thompson wheels on my drill.”
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).
