- Model SG850 - Stump Grinder



The Dutch Dragon stump grinder has been specially developed for mounting onto mobile excavators.

The innovative grinding bit mountings mean the bits can be changed with minimum holdup. As an option the SG850 can be fitted with a slewing motor that allows the grinder to be rotated through 360° without the need to reposition the entire machine so that you can select the most optimum and safe position.
