Coulter Drill
The Supreme coulter drill uses rotating disc coulters to slice through surface residue and hard ground ahead of the seed. Manufactured in Faisalabad by Supreme Agri Implements, it sows accurately in conditions where a conventional tine drill would block, ride up or smear.

What does a coulter drill do?
A tine drill needs relatively clean, well-worked soil. Put it into a field carrying heavy stubble and the tines gather trash until the drill blocks; put it into hard, dry ground and the tines ride up out of the soil instead of cutting in, leaving seed on the surface.
Disc coulters solve both. Each rotating disc cuts cleanly through residue rather than dragging it, and its rolling action penetrates hard ground where a dragged tine skids. Seed then goes into a clean slot at the intended depth regardless of what is on the surface.
That capability is what makes this drill suited to minimum-tillage systems, where the aim is to reduce tillage passes and keep residue on the surface to conserve moisture and protect soil structure. It is the practical middle ground between full conventional tillage and true zero tillage.

- Coulters need sufficient down-pressure to penetrate; too little and they ride over hard ground.
- Keep disc edges sharp — a blunt coulter pushes residue into the slot instead of cutting through it.
- Residue tucked into the seed slot ("hair-pinning") stops seed reaching moist soil; check slots after the first few metres.
