Coil Closing Wheels for Single Disc Openers - a proven aftermarket part to improve productivity

The goal is to get the absolute best outcome in terms of time & money from your seeder… and you will using the RYAN NT Coil Closing Wheels. They have shown fantastic results for most single disc opener seeder brands, including John Deere and Serafin.

There are several reasons we can make this promise…

1. The wheels self-clean and close the furrows firmly, eliminating air pockets, enhancing seed-to-soil contact.

2. The wheels are made with spring steel meaning you won’t need to replace splitting or deteriorating rubber wheels.

3. The coil wheel is designed to make it easy to replace worn cast or rubber closing wheels while still using existing equipment and parts.

With a superb design you get many benefits from our single disc opener coil closing wheel

The key here is to consistently close the seed slot; if you can do this you get two critical productivity issues right – uniform emergence and maximised yields. That’s a promise.

3 reasons we can make this promise:

1. Conventional rubber, spiked or cast closing wheels too often result in poor germination due to reduced seed-to-soil contact or trench cracking…

👉 Not so with coil closing wheels – the auger action of the coil compacts soil tight, screwing the slot closed for a much better press.

👉 The coil shifts an excellent tilth across the soil surface, allowing furrows to retain moisture and avoid cracking.

2. Conventional closing wheels usually require chains attached to the row units to drag soil tilth across the top of the furrow…

👉 Chains tend to pull stubble out and drag it through the furrow pulling seed or drying it out.

👉 By using coil closing wheels, the coil will drag the soil over the furrow and won't pull out the crop residue, meaning you no longer need chains.

 

3. Different conditions may require you to have a variety of closing wheels on hand…

👉 The Ryan coil wheels allow you to close the furrow in all soil types and conditions.

👉 You can change the angle or aggression for the RYAN NT Coil Closing Wheel on single disc opener seeders with an easily adjustable adaptor.

This single disc opener closing wheel will break down sidewall compaction

Wet soils are easily compacted, a big problem during planting…and so is late planting! But no longer with the RYAN NT system. Here’s why…

1. Your patience can wear thin waiting for soils to dry; and worse if another rain is forecast in the near future! The yield penalty for late planting means it’s a balancing act, sometimes forcing you to take a punt and plant in less-than-ideal soil moisture conditions.

2. The next problem is sidewall compaction; seeder disc openers may create sidewall smearing when pushing the wet soil outward to make the furrow, even more so if you have too much down pressure.

👉 RYAN NT Single Disc Opener Coil Closing Wheels are highly effective in breaking down sidewall compaction in such conditions. Much like the spikes on a spiked closing wheel, the coils cut into the side wall and break it down. In addition to that benefit, the coils will then auger the fractured soil over the furrow, leaving the perfect tilth on top for optimum growing conditions.

More outstanding results can be achieved when fitting your existing single disc opener seeder with our RYAN NT Coil Gauge Wheels. The combination can help create the ideal seed environment, leading to even emergence and higher yields. The action of the gauge wheel screws away dry soil, leaving optimum conditions for the closing wheel to screw moist soil against the seed.

Comparison

RYAN NT Coil Wheels vs rubber gauge and spiked closing wheels in muddy conditions…

What our farmers have to say

“When we first tried them there was a huge difference. We only had two units with the wheels on, and the germination of those two wheels compared to the other five in our soil was tremendously better…”

– Tim Leifels of Moree (NSW)

Commonly asked questions from our farmers

Single disc seeder and double-disc precision planter row units use the closing wheels. Tine seeders use the press wheels.
