Angled spiked closing wheels

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. The Zipper Closing Wheel will eliminate this problem.

About the Zipper

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

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

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

Zipper 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 Zipper.

Benefits of the Zipper

Features—Design—Benefits

  • Longer wear, heavy duty cast metal rims & wheels
  • Breaks down sidewall and zips seed V shut at the same time
  • Tubular design of spike allows it to release soil and eliminate plugging while compacting the soil around the seed
  • Angle design doesn't flip or throw soil out; it allows for accurate release
  • As the Zipper closes it creates indentations which allow moisture to sink in
  • 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

  • More aggressive
  • Breaks up sidewall compaction better
  • Pulls more soil from the sidewall in over the seed because the spikes are angled out and down
  • Creates an ice cream cone shape with the soil in and above the seed V (the Mohawk creates a flat ice cream cone shape)
  • Less mud build-up
  • Because of its aggressive nature, the Zipper takes a metal rim while the Mohawk takes a plastic rim
  • Rocks or root balls will not stick

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.

Testimonials

We have ran the zippers on about 500 acres of no-till beans into corn stalks and are quite pleased with the results so far. I have attached some pictures I took of a wet spot that had last year’s grass matted down on it.

I believe that the crumbling action of the spikes combined with the firming action of the solid portion of the wheel is key in getting rid of air pockets in our soil conditions. This holds true in drier areas as well. The spikes tend to break up chunks that the no-till coulters throw out and move that soil back over the seed trench. The wheels then firm the soil without packing it over the seed.

Thanks again for a well-designed product and EXCELLENT service!

In 2014 I purchased 16 rows of Zippers for one John Deere 1770 planter. I planted cotton in one side (shown in left side of photos below) of the field with regular V closing wheels and the other side (shown in right side of photos below) with Zipper Closing Wheels.

We got a hard rain a day or two after planting. Normally with a hard rain, the cotton plants will have a hard time coming up or getting through the firmed soils. Cotton is very susceptible to crusting.

The Zipper Closing Wheels left the soil over the seed row mellower and more cushioned than the soil over the rows planted with regular closing wheels. After the hard rain, the mellower soil didn't crust as bad as the flatter soil surface left by the regular wheels.

Five days later, cotton began to emerge from the rows planted with Zippers (see photo below). It was not yet coming up in the other rows.

We later took an aerial photo of the field (see below). The stand was much better where the Zipper wheels ran. There were more skips in the left side where the rubber wheels ran. My son attributes this difference to quicker emergence and less crusting with the Zipper Closing Wheels.

This year, I equipped four more planters with Zippers.

I was having problems with rocks in the spiked closing wheels last year and was getting mad... Called Schaffert Mfg to get some more Rebounders and fertilizer tubes.

They asked if I would try the "Zipper" closing wheel. I was impressed with the Zippers and they didn't pick any rocks up. Problem solved.

We have three John Deere DB- 60 planters with the Zipper closing wheel on one side of the units. We like the condition of the sidewall behind the Zipper when we first start planting. When the ground is a little more heavy we see that the Zipper closes better. The furrow is closed better on top and eliminates air pockets around the seed.

We have used spike closing wheels in the past but they seemed to move the seed in the furrow, not allowing for proper seed placement. The Zipper won't do that. We believe we are getting better seed placement and better emergence behind the Zipper.
