Our machines have a large cutting head with sharp tungsten teeth used to grind away tree stumps. You are left with a nice pile of organic and very usable tree mulch. This can be put anywhere on your garden to create better quality soil. As you can see in these images one stump can create quite a large amount of mulch. This customer was wanting to replant in the same spot so we had to make sure we did a nice deep ground to remove all of the stump and root system out.
