The RFM NT CWS2000 Coil Closing Wheel has become a proven aftermarket part for planters. This is due to how it self-cleans and closes furrows firm, to eliminate air pockets and enhance seed-to-soil contact for even emergence and significant crop growth. These closing wheels have shown great results for many well-known models, including John Deere Planters and seeders.
Ryan Farming Machinery created the coil closing wheel from the continuous focus on evolving their coil press wheel range for seed drills and planters.
The material of the coil is spring steel, which means you no longer need to replace splitting or deteriorating rubber wheels. The design of the coil wheel makes it easy to replace worn cast or rubber wheels using your existing equipment and parts.
The closing wheels are an effective system that has shown excellent results on both single or double disc seeders.
Conventional rubber, spiked, or cast closing wheels can cause poor germination due to poor seed to soil contact or trench cracking.
The auger action of the coil compacts soil tight and screws the slot closed for a better press than other systems on offer. Further to this, the coil shifts an excellent tilth across the soil surface, which means the furrow will retain moisture and avoid cracking.
Conventional closing wheels on double disc systems usually require adding chains to the row unit. This can drag the tilth across the top of the furrow. Another issue with chains is they can pull out stubble and drag it through the furrow. Which means it could pull out valuable seed or dry out the furrow.
The RFM NT Coil Closing Wheel offers an easily adjustable adapter for single disc seeders so that you can change the angle or aggression of the wheel. Furthermore, enhancing the ability to close the furrow based on soil types and conditions.
Consistently closing the seed slot is critical for uniform emergence in addition to maximizing yields. Open seed slots can cause cold temperatures to descend to the roots, which can result in losses.
Wet soils are easily compacted. As farmers know sidewall compaction can be a problem during planting. When waiting for soils to dry patience is required, but if the next rain is coming or the yield penalty for late planting is growing, it’s hard to wait. Which, in turn, forces farmers to seed their crops in higher than ideal soil moisture conditions.
When planting crops into these conditions, there is a high chance of sidewall compaction occurring. Planter disc openers may create some sidewall smearing while pushing the soil outward toward the furrow.
The RFM NT CWS2000 Coil Closing Wheels are highly effective in breaking down sidewall compaction caused by the smearing action of a disc opener in higher soil moisture conditions.
Furthermore, more, outstanding results can be achieved when fitting your existing disc opener planter with our RFM NT CWS2000 Coil 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 seed. These benefits are in addition to the self-cleaning system and not having to replace rubber wheels.
Natural flex of the spring coil allows the wheel to self-clean.
Keeps the dry soil away from the seed trench.
No more plugging and cracking
Better Germination.
Can change the angle or aggression depending on the seeder and soil type.
Easily retrofit for single disc airseeders.
Ideal for gassing.

Paul Ryan explains, “Whilst building a great product that’s helping feed the world, we’re also making the farmer more productive. It’s exciting to see the growth and changes from expanding around the globe. In the end, it’s very rewarding to see the results after lots of hard work and taking many risks.”
