Forestry mulching is taking down underbrush and normally smaller trees up to about 5" in diameter. (In some areas this is known as forestry mowing.) Mulching cuts or tears underbrush and trees into small sticks or chips that is manageable by racking, burning or just leaving to decay back into the soil. This is somewhat similar to bush hogging weds and small bushes. The underbrush is taking down to the ground, normally leaving the stubble low and feathered so it can be immediately walked on and driven on. Trees are munched down close to the ground leaving a very low stump.
Mulching is best accomplished on smooth ground. For instance, whien mlching where large equipment has left ruts, or land that has been logged, leaving wind rows, and piles of dirt, this complicates and disrupts mulching.
Trachoe mulching helps to offset a lot of problems encountered with skid steer (often known as bobcat mulching. The trachoe booms out to mulch which minimizes damage to the soil and tree roots due to less movement and turning of the machine on the ground. The mulching head is shorter in width which allows it to get into ruts and depressions in the soil better than the wider skid steer heads, also it can detail in between and around trees better.
The trackhoe can mulch areas that a skid steer can not navigate as: banks, levies, ditch and some wet areas. Another advantage is the trachoe cuts from higher in the vegetation down toward the ground and not from the ground up. This allows the operator better contol and visibility. Also more of what will be non=supported limbs and small trees from above that will become over hangers in the road or trail can be taken down.
Various things effect the time involed in mulching. The density, height and trunk size of the vegetation determines the time needed to mulch a given area as does the topography of the land. Another factor is the number of trees that are being left and mulched around.
