Retrofit Double Discs from No Till Retrofit Leaders in Ag - RFM NT

If you’re considering upgrading your tine machine, the RFM NT Retrofit Double Discs are the perfect double disc seeder conversion option. Around the world, the discs are proving to be a preferred alternative to buying a new machine. The changing practices of cultivation, heavier bars, interrow sowing and reduced livestock trampling the ground, has meant conditions for the usage of discs in cropping programs is much preferred these days.

The double disc system can convert most machines manufactured in the last 30 years into a disc seeder. This low-cost system makes light work of stubble and trash conditions in all soil types. It allows farmers to plant early in dry conditions without making a mess or blocking up in the wet.

Most importantly, this system allows you to retain more moisture when seeding than a standard tyne point system. Furthermore, with the disc system, farmers can get their crop in the ground 30 per cent faster than average, which in turn means they use 30 per cent less fuel.

Superior penetration and cutting

Standard double disc systems commonly have the disc coulter side by side, which can be prone to act as a wedge, making it harder for penetration.

RFM NT’s unique double disc opener system features unique offset disc coulters, which allow extra penetration and easier cutting, compared to the standard wedged designs. The lead disc is the driving disc on the ground and is an inch forward from the plain coulter disc. This allows for greater penetration and cutting and no hairpinning.

The plain and serrated coulters work together to give you good tilth and enough soil through for chemical incorporation. It also features a unique front seeding boot design which avoids blocking and gives perfect seed or fertiliser placement by placing it directly at the bottom of the trench. In addition to this, the unique spring-loaded scrapers can help alleviate blocking. Another notable feature is that the system can double chute.

QUICK CHANGE SYSTEM

This multipurpose system can turn any conventional tyne planter into a highly versatile disc planter. Farmers can quickly change over their machine to the disc system and easily convert it back, should the condition require it. The design of the disc system allows it to fit existing tine trip assemblies. They can remove their current shank from the tine trip assembly and replace it with our matching shank. For most setups to switch over, it only requires undoing a couple of bolts or a pin.

In conclusion, with the RFM NT Double Discs, you do not have to purchase an expensive new disc seeder. Instead, you can easily convert your existing planting tyne trip for dual purpose. Additionally, when using the double discs with the RFM NT Press Wheels, you will see another increase in results.

The idea for the double discs came from the Ryan family in around 1983, which means they have refined it for nearly 40 years. Across Australia and the globe, the double discs are proven; notably, programs in eastern Europe have successfully integrated them.
