Coil Closing Wheels, a proven aftermarket part to improve productivity

The goal is to get the absolute best outcome in terms of time & money for your planter… and you will using the revolutionary RYAN NT Coil Closing Wheels. You will see fantastic results in most conditions, including cereal and corn crop residue. The wheels are in the USA and Canada and fit most well-known brands and products, including John Deere planter row units.

The Coil Closing Wheel was created from the continuous focus on evolving their coil packer wheel range for hoe drills and disk planters.

There are several reasons we can make this promise…

1. The wheels self-clean mud and residue build-up to keep you going in the field.

2. The coils close the seed-vee firmly, eliminate air pockets and enhance seed-to-soil contact.

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

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

5. The closing wheels provide excellent results for double disk opener systems.

With a superb design you get many benefits from a coil closing wheel system

The key is to consistently close the seed-vee, fracture the side wall and put loose soil above the seed; if you can do this you get two critical productivity issues right – uniform emergence and maximized yields. Our wheels will do that!

3 reasons we can make this promise:

1. Conventional rubber, spiked or cast closing wheels frequently result in poor germination due to poor 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 better emergence.

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

2. Conventional closing wheels on double disks usually require chains to drag soil tilth across the top of the furrow…

👉  Chains tend to pull out crop residue and drag it through the furrow, pulling out 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 NT Coil wheel gives you the ability to close the furrow and keep it closed in all soil types and conditions, even gumbo soils.

👉  You can be confident that all the seeds are at the bottom of the seed-vee, in good soil moisture, and will have uniform emergence.

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. Waiting for soils to dry could result in yield losses; even more so if another rain is forecast in the near future! The yield penalty for late planting is a balancing act, sometimes forcing you to plant in less-than-ideal soil moisture conditions

2. The next problem is sidewall compaction; planter disk 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 Coil Closing Wheels are highly effective in fracturing 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 crop production results can be achieved when fitting your existing disk opener planter with our RYAN NT Coil Depth Gauge Wheel. 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.

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 disk seeder and double-disk precision planter row units use the closing wheels. Hoe drills use the packer wheels.
