Disc Seed Drills

With better cutting and penetration when the going gets tough, the Seedmatic® Series Disc Drill is the only seed drill you will put out to pasture.

The 4000 Series Seedmatic disc drills are fitted with a large 406mm (16″) concave disc opener & heavy dragarm which are good for extreme stone or rocky situations, or difficult matting type swards such as Kikuyu and high crop residue situations like maize stubble.

The larger rolling circumference gives better cutting and penetration when the going gets tough. A spring-loaded vertical travel of 150mm allows the disc to follow the contour of the soil surface with a more even seed depth placement designed to deliver uniform plant emergence with optimum yields at lower costs.

The Seedmatic drills have a narrow 125mm or 5inch row spacing, giving the seed the ultimate secure opportunity to establish a great pasture or crop. The unique seeding system is extremely accurate, and the infinitely variable gearbox handles most seed volumes and sizes effortlessly.

Included are the Aitchison Electronic area meter for metric or imperial measurements of work done, and the Treadboard & safety rail for loading the Drill with seed or fertiliser.
