Retrofit RYAN NT Small Drill Double Discs for Pasture Seeding and Cropping Farmers
If you’re considering upgrading the tines on your small farm seeder or pasture drill, the RYAN NT Retrofit Double Discs are the perfect option. Notably, we have recently released a system that fits the popular Duncan drills from New Zealand.
Our Discs are an alternative to buying a new machine, saving heaps of money in the process! And the good news, RYAN NT Double Discs work on just about any machine manufactured in the last 30 years, meaning you can get your small farm disc seeder or disc pasture planter today!
Discs are a preferred part for pasture cropping programs, when wanting to achieve minimal disturbance. Especially, when sowing your perennial grasses and winter crops for livestock.
It's never been a better time to use discs, due to changing cultivation practices, no-till equipment, heavier bars, interrow sowing and reduced livestock trampling. Togther, all contributing to higher productivity and profitability.
Our small farm disc seeder and disc pasture planter systems, includes disc coulters that make light work of stubble and trash in all soil types. This means you can plant early in dry conditions without making a mess; and you won’t get blocked up in the wet.
You'll have no issues sowing legumes and clovers into your grasses, even if you have thick grass country, you'll be impressed with the result.
And farmers find they can plant up to 30% faster than average as there is no draft – plus they also spending a lot less on fuel – up to 50%.
The big advantage with the RYAN NT Double Disc opener system is soil moisture retention, far more than using a standard tyne point system.
Get a small farm disc seeder or pasture drill with superior penetration & cutting
Standard direct drill disc systems often put the disc coulters side by side causing them to act as a wedge, making it harder to penetrate the soil. Our discs will outperform tynes in thick grass and won't rip up everything, rather rolling over obstacles easily. Plus there will be a perfect slot cut for seed placement.
The RYAN NT Double disc coulters are offset, allowing extra penetration, easier cutting and no hairpinning. This unique system works brilliantly because the lead or driving disc is on the ground, an inch forward of the plain coulter disc.
The plain and serrated coulters our small farm disc seeder system, mean you get good tilth with enough soil through for chemical incorporation.
Our small farm disc seeder and disc pasture planter systems includes a front seeding boot design. This design avoids blocking and gets perfect seed or fertiliser placement directly at the bottom of the trench; also, the spring-loaded scrapers will help alleviate blocking…and the system can Double chute.

Change from Tynes to Retrofit Double Discs on your small farm disc seeder... and back

It’s as easy as dropping the current shank out from the tine trip assembly and replacing it with our matching disc shank…a simple process involving a couple of bolts or a pin.
The bottom line: You don’t need to buy a new machine; rather, convert your existing planting tyne trip for dual purpose with the RYAN NT Double Discs.

Commonly asked questions from our farmers
Yes, they are greaseable Timkin tapered bearing. There are two bearings to each hub with a rubber seal on the inside. The bearings have the grease nipple positioned between them.
On average, you use 50% less horsepower than you would with a tyne machine. However, many factors influence this requirement, such as soil type, machine configuration, application and what you are trying to achieve.
Deep banding tubes are an option. We have achieved separation with them. It all comes down to soil types and speed.
Very minimal. We recommend that you check disc bearing in the first 100 hours and then grease every 100 hours from thereon.
Yes, they can. It comes down to soil types, speed, and conditions.
The lead disc at the front is always the notched disc.
We regularly plant into hard pastures. The results depend on soil types, speed and conditions.
We recommended starting with 3 spaces on each side. We recommend aiming for a 3-6mm gap at the leading edge of the discs for loam to heavy soils and no more than 1mm for sandy soils. The loam to heavy soils will close the gap between the disc coulters.
Yes, you can. We also stock adapters to suit other tyne models.
Yes, they can. It depends on underframe clearance.
