"CLAMP-ON" SPRING ADJUSTABLE DESIGN TO SUIT MOST BEAM SIZES.
The 580 tyne assembly is a clamp-on design, incorporating a shank to provide efficient trash clearance.

The adjustable single spring is standard at 70kg (155 lbs), however with the optional double spring loading, breakout force is increased to greater than 113kgs (250 lbs). For lighter soil conditions or stony ground, the spring pressure can either be backed off or the inner spring removed to provide an easier jump action.

The assembly features replaceable hardened pivot pins and bushes. The tyne foot will accept a wide range of ground engaging tools including super seeder points, ‘T’-boots & lucerne points. The Shearer ‘T’-boot is specially developed for sowing a range of pasture seeds.
