How to change from a tyne machine to a disc seeder | Farming Australia | RYAN NT Retrofit Discs

RYAN NT has been retrofitting seeders and planters for nearly 20 years now. With our dedication to helping farmers plant better, we have been set many retrofit disc seeder challenges. One of our main focuses is converting tyne machines into disc systems.

This drive to improve farming practices means we have got our hands dirty under many unique machines to get the design right. Below is some info about how we do it and our top rigs that we have upgraded in recent years.

Want a disc seeder? This is how it's done!

One of the unique features of the RYAN NT Retrofit disc seeder system is the ability to turn your tyne seeder into a disc planter quickly. Then, just as easily, convert it back if conditions require it.

We have designed the RYAN NT Retrofit Double Disc system to retrofit most frames and tine trips designed in the last 40 years. There are three main ways we retrofit based on what type of system farmers are using:

1. The RYAN NT Disc and Tyne Trip System. For instance, these are the typical scenarios when you may go with this approach if you’re looking to switch over to discs:

a. Your tine trips may be at the end of their life and need replacing with something more robust,

b. or you may already have Ryan Tyne trips with Tyne Shanks.

Our most common frame sizes for the tyne trips are 2.5×2.5(65×65), 3×3(75×75), 4×4(100×100) and 4×3(100 x 75) – other sizes can be made to order.

2. A uniquely designed leg that will slide into your current tyne trip. These legs could be straight, curved or something even more unique. Commonly this design is for Gason, Gyral, Gessner, Horwood Bagshaw, Bourgault Paralink and DBS machines.

3. Or an adapter that connects to your tyne trip, which allows you to slide the Ryan disc leg in there. We cater for all c-shank tines with an adapter that suits the tine trip, including Morris, Bourgault & Flexicoil systems.

Overall, once you have put the disc system together, it’s usually a couple of bolts or a pin to switch back to your old tyne system, should you need to.

The benefits of the discs will improve your productivity and profits:

You won’t need to buy a new machine; retrofit the current one.
Makes light work of stubble and trash in all soil types.
Plant early in dry conditions with no mess or blocking up in the wet.
Less fuel used and planting will be up to 30% faster.
Offset disc coulters mean no wedge effect leading to greater penetration.
No more hairpinning.
Perfect seed or fertiliser placement with our no-block front seeding boot.

A Strong & Durable Disc Seeder System

Most farmers view purchasing a seeding system as a long-term investment. With that in mind, RYAN NT makes the most robust and durable disc seeder retrofit products.

One of the RYAN NT Disc system’s standout features is a strong bearing and axle system that does not fail. This bearing system has been designed for easy servicing and maintenance, with only one grease nipple per hub that only needs to be greased once a year. Plus, the axles are heavy-duty 30mm axles, which utilise Timken tapered bearings.

In addition to this, the discs have been designed for longevity as they are 4 or 6mm thick, with an 18-inch diameter, as most other brands are 15 or 16 inches in diameter.

The disc legs (shanks) are thick and made of hardened cast steel, which can handle the largest side force pressure.
