By processing trees and other vegetation where they stand, mulching machines eliminate many of the steps involved in land clearing such as site prep, cutting/felling/hauling, and site cleanup. This also eliminates the need for multiple machines such as a bulldozer accompanied by some combination of excavators, tree shears, wood chippers or grinders, and hauling equipment. On simpler jobs only one mulching machine is required, reducing fuel requirements and emissions.
Some mulching machines also have the ability to operate on steep slopes and in small or tight areas, in poor ground conditions, and in wet or snowy weather.
Mulching machines are capable of clearing land of unwanted trees and brush with limited disturbance to soils or desirable vegetation.
