Standard, rubber closing wheels have a tendency to press the soil closed causing a smooth effect, especially when the soil is wet. On a hot, dry windy day, the furrow will crack back open exposing the seed. Eliminate this problem with the Mohawk Closing Wheel.

About the Mohawk

The Mohawk is a 13″ angled spiked closing wheel designed to take the place of standard, rubber closing wheels. It works in all soil types, most notably in the toughest of no-till conditions.

The non-aggressive, 1″ angled blunt spikes on the Mohawk feather the soil in the furrow while simultaneously applying light pressure to ensure the furrow is stitched shut.

As the spikes close they create indentations which allow moisture to sink in, increasing seed-to-soil contact.

Mohawk closing wheels are angled so that when they engage the soil at the 5, 6, and 7 o'clock positions, they are breaking the side wall down over the seed plus compacting the soil around the seed. Then, when they exit the soil at the 8 o'clock position, they are angled such that they release the soil, leaving it compacted around the seed. Because of this, you will not need to drag a chain behind them.

Other closing wheels on the market are aggressive and have the potential of actually flipping seeds out of the furrow. You will not have that problem with the Mohawk.

Farm Journal agronomist Ken Ferrie conducted a three-year study examining closing wheel designs, including the Mohawk. He classified the Mohawk as a firming spiked closing wheel, which are designed to provide both crushing action of the sidewall and firming above and around the seed. Ferrie concluded that in the toughest no-till conditions, wheels like the Mohawk get the job done the best.

Benefits of the Mohawk

Mohawk closing wheels stitching the furrow shut while the G2 fertilizer disc places liquid 2x2 behind a John Deere planter


  • Stitches seed V shut
  • Uses existing wheels and bearings, and replaces tire with the Mohawk ring, saving you $$$
  • Breaks down compacted sidewall and closes the furrow at the same time
  • Longer wear, heavy duty cast steel spikes
  • Feathers the soil in the seed V with its wide track design
  • Designed to break up compaction without being too aggressive
  • 1″ spike will not get too close to or disturb seed
  • Allows for better seed-to-soil contact

Eliminates Common Problems

  • Compacts the soil better than straight-fingered wheels
  • Moves soil with minimal compaction into the furrow
  • Eliminates air pockets
  • On a hot windy day the trench will not break back open

Where They Work—Suitable for Many Soils

  • Made to work in tough soils
  • Works in no-till or conventional

Ease of Installation

In the Field Performance

Mohawks VS Standard Closing Wheels

This graph shows data from a field of soybeans planted on May 29, 2013 near Ponca City, OK with Black Machine tool bar equipped with John Deere 7200 Max Emerge II row units. Some rows had standard rubber closing wheels and some had Mohawk Closing Wheels.

2.5″ of rain fell on the field a week after planting, causing erosion down the rows even though the farm had not been cultivated in 5 years.

Stand counts were taken June 15, 2013 on varying degrees of slope down 36′ row.

The steeper the slope the greater the erosion of the soil down the furrow, and the less stand counts behind the regular closing wheels.

I purchased two rows of Mohawk wheels, and put them on my 16 row planter the same time I installed 14 rows of Exapta's Thompson wheels.

The Mohawk wheels have always left the row covered better, and did a smoother job. They were also about $20 per row cheaper. And while the Thompson wheels are worn out after 3 seasons, the Mohawk wheels show practically no wear.

The best addition I added to the planter this winter has been the Mohawk Closing Wheels.

Half of my planter were Copperheads and the other Mohawks. Both of these wheels do a better job than the stock closing wheels, but the Mohawks have a distinct edge.

The Mohawks sealed the seed slot better and with less pressure while crumbling the top soil. The Copperheads mostly pushed the slot together which made it prone to open back up with lack of rain. The Mohawks never had that problem.

In heavy residue, the Mohawks always sealed the slot while I had to crank down the pressure on the Copperheads to achieve the same results and sometimes still not seal the slot.

I do 50% no-till. I bought Mohawks 3 years ago and ran 1 rubber wheel and 1 Mohawk wheel. The Mohawk broke the seed wall better and helped it to not crust. It works good in conventional planting too.

In 2014, the Mohawk closing wheel versus JD rubber closing wheel performance was very evident. No side wall compaction with the Mohawk compared to a compacted side wall with the JD closing the seed trench.

I planted corn with one Mohawk Closing Wheel and one regular press wheel on each row.

The soil on the Mohawk side of the rows was soft, while the soil on the regular press wheel side was hard and compacted. When the seeds sprouted and grew, the plants all emerged through the softer soil on the side where the Mohawk wheels had gone.

Mohawk Distinct Features Over The Zipper

soil in and above the seed V. Mohawks (right) create a
flat ice cream cone shape.

  • Creates a flat ice cream cone shape with the soil in and above the seed V (the Zipper creates a more rounded ice cream cone shape)
  • The Mohawk takes a plastic rim while the Zipper takes a metal rim
  • Slightly less aggressive than the Zipper
  • Mohawks are more economical when using your existing wheels and bearings

I have used the Mohawk closing wheels, and more recently added some Zipper wheels, for several seasons now in both no-till and tilled ground, and have planted corn, soybeans, and milo with good results. I like how the wheels still maintain the same depth of penetration even if I’m a little too heavy on the down pressure. No flipping chunks of soil and seed out.

In watching the planter run this spring, it seems like the Zipper wheel might have a little faster “sewing” action than the Mohawk, meaning when the soil was a little heavy or no tilling into fall killed sod, the Zipper rows seemed to have a little more fluff to them.

In normal no tilling situations, both wheels performed great.

An advantage for the Mohawk is if your planter closing wheels are in good shape, you swap the rubber tire for the Mohawk and you’re ready to go at an attractive cost.

I don’t see how anybody can go wrong with either wheel.
