The SEPPI M. mulcher & shredder STARSOIL hyd is a multifunctional tiller-mulcher for above and below ground mulching of wood, stumps and roots, road maintenance and construction, tilling of soil, and stone crushing. It is designed for high hp tracked and wheeled prime movers. With dual parallel gear transmission, integrated cooling, variable speed motors, and carbide hammers, the SEPPI STARSOIL hyd works to a depth of 40 cm [16”], mulches wood up to 40 cm [16”] and crushes stones up to 30 cm [12”]

STARSOIL hyd features a reinforced frame made of wear-resistant steel AR 400. This versatile soil tiller is suitable for hydraulic machines, high HP track and wheeled carriers with power classes between 150 and 250 HP (200-350 bar / 3,000 – 5,075 psi). It is equipped with a hydraulic system with 2 hydraulic motors M-BOOST™ for high pressure and high oil flow. Speed adjustment & display in cabin. The drive design with integrated cooling (with panel to monitor and control oil temperature) and with spur gear motor is especially slim and space saving. Equiped is the STARSOIL with the new generation patented rotor V-LOCK with efficient tool combination of the new type, ULTRA MONO PROTECT and MONO EXTREM with additional tungsten carbide inserts at points most subject to wear. The STARSOIL hydraulic has versatility and high performance with minimum energy consumation thanks to its lightweight construction (2900 – 3500 kg / 6,500 – 7,600 lbs). Available with compacting roller with hydropneumatic levelling or with hydraulic guard frame.

The result of 75 years of innovation: more power, longer lifetime, more productivity!
