Seed Smith

Introducing the Seed Smith Rate Controller
Seed Smith is now ISO
Unplug Topcon.
Plug in Seed Smith. Go seeding with Greenstar.


Built by us from the ground up
Due to feature limitations and supply issues with 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. As of 2025 our units are seeding on with Morris, Ausplow, Bourgault and Simplicity machines, including models with section control, tank scales and electric/hydraulic/ground drives.
Pricing
Technology is evolving rapidly in agriculture. We've all bought state of the art products in the past that quickly become obsolete. That's why we deliver our service as a rental model, 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/replace 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.
​​
For peace of mind we keep spare units all over the country. If you have a unit fail, it's on us to replace it ASAP. No warranty disputes, ever.
