An important segment of the vast Seppi range is the excavator mulchers: 8 models, each of which is available in different working widths and with different accessories. This is completed by the new hydraulic stump grinder and site preparation machine, the Kastor hyd (pictured). The excavator-mounted Kastor hyd is based on the classical stump grinder Kastor, for PTO drive. The working principle of both Kastors is that a narrow-but-large rotor carves into the stumps and swings from one edge of the stump to the other. It does not matter what diameter the stump is, it can virtually be any size. The tractor mounted Kastor will work as deep as 14 inches, but this can be deeper, depending on the condition of the soil. The Kastor hyd on an excavator will work much deeper. For more information, visit www.seppi.com.
