Stump Grinding

Once a live tree is cut down, the roots soon stop growing. There is no longer the stimulation from hormones produced in the canopy to encourage new growth of roots. In most cases, the roots stop growing within a matter of days or weeks, and usually die shortly after that. Some tree species develop root sprouts, however, pushing out new stems from the root system. If allowed to grow, these shoots will produce the hormones and the carbohydrates the roots need to survive.

There are several methods of removing tree stumps. Mechanical routing is the quickest method. Stump grinding machines generally operate with a large flywheel equipped with cutting teeth. The operator moves the cutter head over the stump, grinding it away a little at a time.
