Retrofit RYAN NT Double Disks for exceptional Zero-Till Farming results
If you’re considering upgrading your hoe drill, the RYAN NT Retrofit Double Disks are the perfect option.
Our disks are an alternative to buying a new machine, saving heaps of money in the process! And the good news, RYAN NT Double Disks work on just about any machine manufactured in the last 30 years!
Discs are now an integral and preferred part of the best cropping programs. These, coupled with changing cultivation practices, no-till equipment, heavier bars, interrow sowing and reduced livestock trampling all contribute to higher productivity and profitability.
The system includes disk 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.
And farmers find they can plant up to 30% faster than average and are spending a lot less on fuel.
Another big advantage with the RYAN NT Double Disk opener system is soil moisture retention, far more than using a knife system.
You get superior penetration & cutting with our double disks
Standard disk systems often put the disk coulters side by side causing them to act as a wedge, making it harder to penetrate the soil.
But the RYAN NT Double disk coulters are offset, allowing extra penetration, easier cutting and no hairpinning. This unique system works brilliantly because the lead or driving disk is on the ground, an inch forward of the plain coulter disk.
The plain and serrated coulters mean you get good tilth with enough soil throw for chemical incorporation.
The system includes a front seeding boot design, so you avoid blocking and get perfect seed or fertilizer placement directly at the bottom of the trench; also, the spring-loaded scrapers will help alleviate blocking…and the system can double chute.

Change fast from knives to Retrofit Double Disks... and back
Quickly turn your conventional knife hoe drill into a highly versatile disk planter with the revolutionary RYAN NT multipurpose disk system.
Then just as easily convert it back if conditions require it.
The RYAN NT Retrofit Double Disk system easily attaches to existing tine trip assemblies.
It’s as easy as removing the current shank from the tine trip assembly and replacing it with our matching 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 Disks.
For even better results, invest in RYAN NT Packer Wheels that work in tandem with the revolutionary Double Disks.

What our growers have to say...
“They just cut straight through and sowed straight in. There was no blockages or anything like we had found in the past with our knife point system. The germination was very, very good”
– Ash Rowe of Ardrossan (SA)
Commonly asked questions from our growers
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.
Disk hubs come pre-greased. We recommend giving them their first service in the first 100-200 hours or after the first rain after the first 100 hours. It’s as simple as giving them a quick nip up (and making sure not to over-grease).
Then once a year after that.
On average, you use 50% less horsepower than you would with knives on a hoe drill. 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 disk at the front is always the notched disk.
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 0.12″-0.24″ gap at the leading edge of the disks for loam to heavy soils and no more than 0.04″ for sandy soils. The loam to heavy soils will close the gap between the disk coulters.
Yes, you can. We also stock adapters to suit other tyne models.
Yes, they can. It depends on underframe clearance.
