While forestry mulchers are powerful machines, they do have limitations on the size of trees they can efficiently handle. Forestry mulchers can typically mulch down trees with a diameter between 6 and 8 inches. Any larger, and the tree can potentially do damage the machine. While some forestry mulchers can tackle trees larger than 6-8 inches in diameter, processing these significantly increases project time and cost. In these cases, traditional land clearing methods might be a more efficient solution.
