Automatic reset stone protection

The ST has been designed to cultivate in a wide variety of soils, including shallow, rocky and stony soils. A heavy duty spring mechanism protects the cultivator when encountering large rocks, and the pivoting geometry enables the tine leg to pivot upwards and rearwards to skim over the obstacle before immediately re-engaging at the preset cultivation depth. In addition to the spring mechanism, the leg is protected by a shear bolt – which may be fitted in two positions to provide differing penetration and tine operating angles – a real benefit in the hardest soils.

Advanced frame design

The main frame and brackets are produced from high grade 100mm square steel box section which provides exceptional strength and durability. The 800mm frame clearance and 1000mm distance between the main frame tubes has been designed to prevent trash blockages – and which also enables the ST range to operate at high forward speeds.
