Who is the GrassFarmer® Disc Drill Designed & Built For?
The GrassFarmer® is built for pasture-based livestock farmers working in tougher conditions who want to take control of their pasture management and get better returns.
If you’re running sheep, beef, or dairy, you know that timing is everything. Plant when conditions are right, and you get strong germination, better feed, and healthier stock. If you miss the right weather window, your germination suffers and you’re left short on feed, ultimately affecting your returns.
The GrassFarmer® is the entry level seed drill that hits the sweet spot: quality seed drill performance at an owner-operator price, giving you the ability to sow when you want to — not when the contractor is.
They vary in price, functionality, size and upkeep – Contact us and we’ll help you identify the right model for your requirements.

Why Choose a Disc Seed Drill? | The Concave Disc System
At the heart of the GrassFarmer® Disc Drill is a heavy-duty 350mm (14″) concave single disc opener, staggered for efficient trash flow. Each disc is individually sprung, meaning it can deflect independently over rocks and uneven ground without transferring shock through to the machine. As a general rule, Aitchison disc drills are among the best-performing seed drills available for stony conditions — and the individually sprung disc system is a big reason why.
These large 14″ concave discs are particularly effective in matted or dense pastures, cutting through where smaller discs bog down or clog.

Sponge Seed Distribution System
All GrassFarmer® models feature the unique Aitchison® sponge seed distribution system — a long-proven design trusted by farmers for over 50 years and used across both the GrassFarmer® and Seedmatic® drills.
At the heart of the system is a unique sponge metering unit that handles the selected seed gently and accurately, without cracking or damaging the product. Whether you’re sowing fine grasses, coated seed, larger legumes, or heavy blends, the sponge system delivers consistent, reliable distribution across the full width of the drill.
Sowing rates run from as little as 1kg/ha right up to 350kg/ha — the versatility you need when you’re dealing with different seed types. A variable gearbox (with two ranges) rotates the sponge disc to give you precise control over your rate, making it straightforward to dial in the right output for any job.
The system is gravity-fed, so there’s no complicated air system to maintain or troubleshoot. Simple, Effective & Proven for over 50 years.
