PTÂ tine coulters are mounted in four rows on equal length arms. The top mounted coil spring delivers 60kg of pressure at the tip for improved penetration in min-till seedbeds or when drilling direct. The narrow (12mm) tip ensures minimal disturbance for improved weed control. The easy to replace tip has single bolt fixing and a tungsten carbide tip ensuring long life performance.
Solo drills with PT coulters feature 4 rows of coulters for maximum inter row clearance this allows the drill to handle large amounts of trash without blockage. Drills fitted with a cultivator have 3 rows of coulters to minimise the overall length of the drill.
