The SPEC HD (heavy-duty) is the more robust version of the standard SPEC cultivator. This three-row cultivator is designed for stalk cultivation and ploughing. With double spring suspension and updated rocker arm geometry, it can withstand a much higher ground load compared to the standard machine. The minimum operating force is 550 kg per tine, which, once the movable wings have been removed, allows for aggressive ploughing to a depth of 30 cm. The range of rollers, different load-bearing points and profiled tines complement the features of this versatile and durable cultivator.
