Stump grinder for excavators

The smaller version of SEPPI stump grinder KASTOR hyd is the MIDI-KASTOR hyd – a stump grinder for small and medium excavators.

SEPPI MIDI-KASTOR hyd grinds the stumps as deep as 30 cm [12 inch] below the ground. Any stump diameter can be eradicated, by swinging the excavator arm from one to the other side. The result is a fine mulch that may be easily incorporated into the soil and mixed with the ground, which fosters a fast decomposition. The stump has been removed completey, the soil is ready for new planting. The Rotor disc is equipped with very aggressive HRC-tooths. The specially developed angle of cut allows an ideal use of power.

Rotor disc width: 10 cm [4″], diameter 60 cm
