Manual for
B-70 Mulch Spreader
INTRODUCTION:
This manual is designed for step by step instructions of the operation, care, and maintenance of the B-70
Mulch Spreader and, in addition, it contains illustration and descriptions of a complete list of parts and
components for easy identification. For best results and to insure longer life of the equipment, please follow
the instructions carefully. For your safety read the entire manual before operation of this unit.
DEFINITION OF MULCHING:
Mulching is the process whereby a vegetative mulch such as hay or straw, sometimes excelsior or other
wood product or other vegetative material is spread on previously seeded areas to promote germination,
while providing temporary erosion control.
THE FINN B-70 MULCH SPREADER AND HOW IT WORKS:
The FINN B-70 Mulch Spreader will apply vegetative mulch at a fast and uniform rate (with the specified
amount of adhesive material, if so desired) utilizing a minimum amount of manpower.
The baled vegetative mulch material is placed on the feed chute and separated by the bale feeder as he feeds
these bales into the shredder housing. In the shredder housing a combination of beater chains and air cur-
rents separates the mulch into individual fibers, which are drawn into the blower housing and blown through
the discharge assembly onto the seedbed.
TOWING VEHICLE:
The truck used to tow the Finn B-70 Mulch Spreader should have a bed large enough to carry the quantity
of mulch needed for economical operation. The truck must be equipped with a ball or pintle type hitch to
tow the Mulch Spreader. This hitch should be mounted as near to the end of the truck bed as possible. Use
a 2” ball rated 6000 lbs. (2721 kg). The tow vehicle must be able to support 600 lbs. (272 kg) down on its
hitch.
LOADING BALES:
Load the bales of mulch on the truck bed with binder twine or wire on top rather than on the side. This
makes it easier to grab the bales while the Mulch Spreader is in operation.
Place the first layer of bales “lengthwise” on the truck. The second layer of bales should be placed “cross-
wise”. Alternate successive layers lengthwise and crosswise in order to secure the load.
Leave enough room at the rear of the truck bed for the bale handler to stand.
