THE FINN BARK BLOWER AND ITS FUNCTIONS
The FINN Bark Blower is an apparatus for conveying and discharging bulk materials, such as bark
mulch, at a fast and uniform rate while utilizing a minimum amount of manpower. The product to
be used is generally composted and processed, then used as a soil amendment, ground cover for
erosion, weed control, or for decorative purposes on landscaping (bark mulch).
This manual is intended to provide step-by-step instructions on the operation, care, and main-
tenance of the Bark Blower. In addition, it contains illustrations and a complete list of parts and
components for easy identification.
HOW THE BARK BLOWER WORKS:
The bulk material is loaded into the hopper by a loader or by an infeed elevator. Located at the
bottom of the hopper is a drag conveyor that conveys the bulk material to an opening containing
a feed roll. The feed roll and drag conveyor feed the bulk material into a rotary air valve. The
rotary air valve is specifically designed and built to handle tough, fibrous material. The function of
the rotary air valve is to take the bulk material into open pockets exposed to the outside air, and
to convey it to an area where the pocket is closed off. At that point, a high-pressure air stream,
created by the blower, is channeled through the pocket and carries the material through the hose
for discharge.
NOTICE
For best results and to ensure safe operation and long life of the equipment, please read
and follow all instructions carefully.
TOWING VEHICLE:
The truck used to tow the FINN BB-302 Bark Blower must be equipped with a 2-5/16 in. ball or
pintle-type hitch. This hitch should be mounted as near to the end of the truck bed as possible.
The tow vehicle should be fully wired for the following: trailer marker, turn, and stop lights as well
as electric brakes.
