The RYAN NT Coil Press Wheel is answering seed-to-soil contact challenges when seeding.

The self-cleaning and self-closing action of the coil wheel has made it a revolutionary press wheel.

Rubber vs Coil Press Wheel

The unique action of the coil system enables superior germination as it presses out air from around the seed. The benefits of this action include better seed-to-soil contact and no compaction. These press wheels stop plugging, a hassle commonly seen with rubber systems. The press wheel plate comes in a variety of hole patterns to suit most bearing and hub stud patterns.


The Ryan family’s mission is to help farmers improve crop yields. Our wheels get air out of the ground in turn giving superior seed-to-soil contact. The wheels pack around the seed, NOT on top of it. That’s exactly what the RYAN NT Coil Wheel does! You will get amazing results; that’s our promise!

Move over rubber wheels. Farmers have tested the RYAN NT Coil Gauge Wheels in soils and conditions around the world.


The wheels have proven themselves in wet and dry situations and light and heavy stubbles. By using this system, you will have less downtime when planting.


Farmers can easily fit the RYAN NT coil wheel into their machine, which suits most disc planting units. The retrofit design means you can easily replace worn rubber gauge wheels using existing equipment and parts.


The coils flex to allow mud to pass through, usually stopping a disc machine using conventional gauge wheels.


The gauge wheels are spoked, further allowing mud to flow through in damp and sticky conditions. We have also narrowed the gauge wheel as wider gauge wheels often run on previous stubble rows.


Brett Ostberg of Red River Valley, North Dakota, states, “Well, we put your gauge wheels to the test in the heart of Red River Valley gumbo in the wettest spring in a century. They may have collected mud, but they kept the disc clean and never stopped turning. Very Impressed!”

The RYAN NT Closing Wheel is a proven retrofit upgrade for planters due to how well it self-cleans and closes furrows. These features eliminate air pockets and enhance seed-to-soil contact for even emergence and significant crop growth.


The wheels have shown excellent results for many well-known models, including single-disc seeders and double-disc planters. The auger action of the coil compacts soil tight, breaks down sidewall compaction and screws the slot closed for a better press than other systems on offer.


Conventional rubber spiked or cast closing wheels can cause poor germination due to poor seed-to-soil contact or trench cracking. The coil’s material is spring steel, which means you no longer need to deal with splitting or deteriorating rubber wheels. The design makes replacing worn cast or rubber closing wheels easy, as you can use your own existing equipment.

Evolution Of The Coil Wheel

Since planting first began, the priority has always been about seed-to-soil contact. Planting started with tine seeders and tine harrows covering the seed. Then came press wheels, steel, plastic, and rubber in various shapes and designs from V shape, flat, dome, pneumatic and semi-pneumatic. The constant aim was to get more productivity and better germination.


The RYAN NT Spring Coil Press Wheel has evolved from a Canadian innovation: the Coil Packer. Some 30 years ago, Austin Ryan found that the Coil Packer on his seeder was leaving his red soil too crusty. Being a creative thinker, he heated a piece of wire into a pig’s tail shape as the first prototype.


This prototype led to a gang model that could fit multiple wheels evenly spaced along an axle in line with the seeder planter tines. Demand then started for a single-press wheel model. The wheel further evolved into having different width models (2 and 3 coils).

As time progressed, there was the requirement for additional modifications to the coil wheel so it could suit other various seeders, parallelograms, precision planters and disc air seeders. Now, the RYAN NT Coil Wheel is working in a number of countries and soil types and conditions around the world.
