The SFM forestry tiller and soil stabilizer for tractors from 160 to 300 HP can mulch standing trees with a diameter up to 30 cm, stumps with a diameter of 45 cm and has a working depth of 30 cm. This combo machine has been designed to work at two distinct working speeds; high revolution per minute for grinding standing trees or low revolution per minute for stabilizing soils with high a presence of stones. The SFM can be equipped with three different options: a support roller that helps to adjust the working depth, a hydraulic pushing frame to mulch standing trees or a grading blade to level the ground.
