Welcome to Ironstone Ag
The Australian Ag Technology Innovator
Introducing the Seed Smith Rate Controller
Seed Smith is now ISO
A true plug-and-play solution. Unplug Topcon. Plug in Seed Smith. Go seeding with Greenstar.
Built independantly from the ground up
Due to technical limitations and supply issues with the Greenstar rate controllers, we decided to make our own to better service the end user. Our two models are direct bolt-in plug-in replacements for Topcon CM-40 and EM-24 Apollo modules, utilizing all existing harnesses on your machine. Now you can run your air seeder completely through a John Deere display and acheive full integration.
We currently offer our product to suit Ausplow, Morris and Bourgault seeders, including varients with section control and tank scales.
Pricing
Technology is evolving rapidly in agriculture. We've all bought state of the art products in the past that have now been superceded. That's why we make our units available to rent, so you can keep your farm equipment up to date with the most current technology.
​
​SSRC-Main $2100+gst/year
SSRC-Aux $1800+gst/year
​​
The Ironstone Difference
Every 3 years we take back our units and completely rebuild them. Hardworking components are replaced, and physical upgrades are made on top of software updates. That means the risk of failure during seeding is minimized, you're always running fresh electronics.
​
A typical 3 bin non-section control machine requires just one SSRC-Main module.
A 4 bin section control machine requires one SSRC-Main and one SSRC-Aux module.
A 6 bin section control machine requires two SSRC-Mains and one SSRC-Aux module.

Our background
We're a small company with big ambitions. Founder Alec Wiles ran Marwonga PFS for four years, specializing in on-farm repair services for various agricultural electronics. During this time, he identified a gap in the industry for making Morris ICTs compatible with Greenstar. Starting with off-the-shelf circuit boards, electronic parts, and plenty of cables, we tested the concept on two machines over two seasons. That's how Seed Smith was born, and in 2023 Marwonga PFS morphed into Ironstone Ag to take it to a commercial level. Today we're proud to offer Australian farmers a proven and reliable professional product.
