    How difficult is it to perform maintenance on the machine?

    ECHO Bear Cat products are designed with ease of maintenance in mind. Proper maintenance is vital and should be performed routinely with blades, belts and bearings being most important.

    How long will the chipper blades last on my chipper/shredder?

    Depending on the type of wood, age and cleanliness, chipper blades will work well for between five and ten hours. Dry, dirty wood will dull the blades faster.

    What are the chipper/shredders designed for?

    The ECHO Bear Cat chipper/shredders are designed to effectively reduce the volume of wood, leaves, and other organic material.

    What is the maximum size of material will these machines chip or shred?

    The ECHO Bear Cat 2" chipper/shredder will chip up to 2"and shred up to 3/4" diameter material. The ECHO Bear Cat 3" chipper/shredders will chip up to 3" and shred up to 3/4" diameter material. The ECHO Bear Cat 5" chipper/shredder will chip up to 5" and shred up to 3/4" diameter material.

    When should I chip?

    If you don’t plan composting the material, material is green and stringy or larger than 3/4" in diameter.

    When should I shred?

    If you plan on composting or if the material is smaller than 3/4", use the shredder. Shredding is also an efficient way to reduce the volume of leaves or prunings.
