Substantiating optimum parameters and efficiency of rotary brush cutters

The problem of untimely forest thinning is quite common in today's society. It leads to the emergence underbrush, which negatively impacts growth and development young trees. Therefore, this work aims estimate feasibility applying a new rotary brush cutter model eliminate excessive vegetation. dependence tractor's speed when removing underbrush with different diameters tree trunks was established by performing mathematical modeling optimize parameters. Three types flexible inertia cutting devices were investigated: flat knives, sprocket chains, knife chains. Knife chains are most optimal choice as they cut plants efficiently (94.61% 92.5% for two-year three-year respectively). They also show lowest energy consumption trunk between 1 2.4 cm diameter. Further experiments required determine if developed can be used more neglected forestry stands.
