The SEPPI STAR-FC hyd is a multi-purpose stump grinder and soil tiller for excavators from 15-35 tons [30,000-70,000 lb]. It is ideal to grind stumps and roots, but also to crush stones, even at depth.

With the aggressive patented rotor of new generation V-LOCK with efficient hammer combination of the new type, ULTRA MONO PROTECT + MONO & ULTRA MONO EXTREME with additional tungsten carbide tips STAR-FC hyd mulches wood up to 40 cm in diameter and crushes stones up to 15 cm, and tills as deep as 30 cm below the surface. Very strong frame, for a very long life made of wearresistant steel with tempered counter knives for a perfect mulching result.
