The materials you are breaking up and the size of the job are the primary considerations when choosing equipment. A gas-powered or towable chipper is ideal for heavy-duty jobs, such as large branches. Stumpers are also heavy-duty equipment, but they are used for tree stumps with large diameters. An electric chipper or shredder would be enough for smaller jobs like clearing small branches and leaves. Remember to consult the owner’s manual before operation as this machinery can be dangerous.
