Get rid of the stump completely, in a short time!

KASTOR hyd grinds the stumps as deep as 50 cm [20”] below the surface and any diameter. 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 quick decomposition. The stump has been removed completey, the soil is ready for new planting. The Rotor disk is equipped with very aggressive HRC-tooths. The specially developed angle of cut allows an ideal use of power. The Interface for spider excavators, available as an option, also works as a shovel. It helps mixing the ground stump chips into the soil, so to completely cover the whole left by the removed stump.
