Coil Press Wheels from the No Till Retrofit Leaders in Ag – Ryan NT (formerly RFM NT)

Ryan NT (formerly RFM NT) has a long history of manufacturing press wheels in Australia. The CWS2000 Spring Coil Press Wheel is answering challenges found with seeding systems. The unique self-cleaning and self-closing action of the coil wheel has made it a revolutionary Australian seeder press wheel.

Get great germination

The Ryan NT press wheel is self-cleaning. It works in heavy trash, sticky soil conditions, and sand and it isn’t affected by small rocks. The unique coil design presses air from the soil around the seed, producing great seed-to-soil contact while maintaining precision seed placement at the desired planting depth.


The unique squeezing action of the coil self-cleans sticky soil and trash, avoids picking up the seed and outstandingly closes off the furrow. The coil wheel handles stubble exceptionally, which is essential to avoiding picking up seed from the furrow.


The coil wheels naturally squeeze the seed, which reduces putting too much pressure directly on the surface, which can lead to crusting or air pockets around the seed.


The good soil-to-seed contact created by the Ryan NT (Formerly RFM NT) press wheels allows seeds to germinate with ease. It creates an excellent loose tilth above the seed and a hard press, which gives farmers a better potential for a good yield. As the coil wheels do not build up with mud or trash, they allow for precise seed placement.

Options to suit your machine

The 16” coil press wheels are available with 2 or 3 coils to match the closing action needed.


The Ryan NT CWS2000 Spring Coil Press Wheel is available in:


  • A standalone rear mount press wheel assembly;
  • A simple retrofit upgrade to other press wheel models or;
  • A tyne mounted model.

The tyne-mounted model for precision seeding can come with or without a seeding boot. The Spring Coil Press Wheel is eliminating the hassles and pitfalls of conventional rubber systems. For instance, the material of the coil is spring steel, which means farmers do not have to replace splitting or deteriorating rubber wheels. It has been proven successful in most conditions from sticky trash to sand.


These drill press wheels have shown excellent results when planting cotton, small grains, canola, corn, soybeans and grasses.

What are the benefits to press wheels?

Using press wheels correctly, can significantly increase emergence and improve seedling durability.


The main benefits for using drill press wheels include:


  • Increase seed-soil contact
  • Maximise moisture retention
  • Increase local soil compaction, which restricts insect movement and consequent damage to seeds and seedlings
  • Reduce emergence depth by decreasing the distance between the seed and the soil surface
  • Improve uniformity of soil coverage across the width of a planting machine
  • Close the furrow to prevent surface light penetration, reducing the risk of premature sub surface leaf emergence
  • Concentrate rain into the seed furrow, promoting faster secondary root development

Ryan NT is a leader, in Australia and the world, in developing and manufacturing press wheels and other equipment for no-till farming. The company now offers several types of coil wheels including gauge wheels and closing wheels. The Ryan NT Press Wheels can achieve even greater success when used with the Ryan NT double discs.
