Coulters

Coulters are castoring disc attachments fitted in front of the shank to assist pasture renovation and cultivation where surface cover is present. By opening the surface ahead of the shank, coulters help maintain the Yeomans philosophy of minimal soil profile disturbance, allowing the shank to lift and loosen the soil below while the surface remains comparatively intact. This makes coulters particularly suitable for pasture renovation, oversowing, and applications where surface structure is to be preserved rather than aggressively cultivated.

Coulters are recommended in:

• Densely matted pastures where grass roots spread laterally near the surface rather than penetrating deeply.
• Old or compacted grazing paddocks with a tight grass mat
• Irrigated or high‑rainfall pastures where surface root density is high
• Pastures with vine‑type or surface‑creeping plants, where coulters prevent material building up on the shank and frame
