4. Familiarization
The Wallenstein BXMC3409B chipper / shredder is designed to
chip or shred small scrap lumber, small trees, brush, branches,
leaves, and other wood material.
When wood material is put into the chipper hopper, the rotor
pulls the material into the machine and cuts it into wood chips.
When brush, bark, or leaves enter the machine through the
shredder hopper, the shredder knives cut the material into
mulch. The machine then blows the wood chips or mulch out
the disharge chute. A Vanguard® engine provides power to the
machine.
