These tough units are built heavier than any engine-driven unit in their class and come in 3 sizes: as an implement, the BIO-80 unit weighs 135 lbs, the BIO-100 weighs 217 lbs., and the BIO-150 weighs in at 278 lbs. BCS has purchased the BIO-100 size from Caravaggi (and 2 other vendors) in Italy and marketed it as their own since the late 1980s. Currently, the BCS "branded" chipper/shredder is manufacturered by Del Morino of Italy. Although we can sell our customer the BCS "branded" BIO-100 model, we recommend the Carravaggi brand of chipper/shredders instead, primarily due to the fact that they come stock with sharpened serrated knives in the shredding chamber AND much nicer and wider wheels than the BCS "Branded" chipper/shredder. This allows for better traversing of rough ground AND for better chopping of material that is run through the shredder chamber.
All units feature Hammermill-type shredding chambers; the hammers are hardened steel and reversible. Unlike the units that BCS sells (which have square, blunt hammers), all 3 Carravaggi chipper/shredders come with sharpened, serrated hammers (they are actually heavy-duty sickle bar blades), so material put in the shredder is “chopped up” rather than “beat to pieces”. This makes the chipper/shredders we offer less prone to clogging when shredding wet material, since blunt hammers tend to make "pulp" out of wet material. The 80 and 150 models also have a “quick clean” feature which, in the event of a clog, allows the operator to use a lever to safely open the discharge screen on the bottom of the unit ***while the unit is running***...the clogging material is instantly discharged when the screen in opened. The lever can even be locked in a “half-open” position if conditions are such that the screen wants to clog repeatedly; the material will come out over the top of the partially-open screen without clogging, no matter how wet the material is. All units are equipped with a single hardened chipping blade mounted to the flywheel for the chipping action; this blade is removable for sharpening or replacing when worn out. The BIO-100 model has a 37 pound flywheel, and the 150 has a 42 lb. flywheel…this gives these units amazing power to handle large woody material through the Chipper (although if you’re using a minimum-size engine to run it [for example, an 8hp engine to operate a BIO-100], you will run out of power eventually and have to back off feeding it and let the engine ‘catch up’.) Essentially, while all 3 units perform both Chipping and Shredding functions, the 80 is a GREAT SHREDDER and a good chipper, the 100 is a GREAT CHIPPER and a good shredder, and the 150 is excellent at BOTH. All do the ‘other’ job well enough, but they shine in the highlighted capacities… So, choosing your model is not so much based on tractor size, but what job you will primarily be doing. For example, some customers who have a 14hp tractor purchase the BIO-80 chipper/shredder, because they were primarily shredding material for compost and don't "need" a larger model. Conversely, if your main task is wood chipping and not really much shredding, the 100 is the best economic choice… and for applications where BOTH functions are desired in equal parts (and you have the tractor HP to run it), the 150 is the unit of choice.
The discharge screen is located on the lower quarter of the shredding chamber, and the screens are available with hole sizes from 1½” down to 5/16” on some models (this small size is effective for cracking corn for feed). Changing screens is a matter of 5 to 10 minutes on all models. Each unit comes with one screen, BIO-100 also comes with “rods” to replace screen if desired (the resulting ‘slots’ allow larger openings for wet material to come out without clogging, since the BIO-100 does not have the “quick-cleanout” feature). BIO-80 has adjustable-height skid/stand for transport and to support the unit when off the tractor; larger units have adjustable-height caster wheels with legs that drop down to support the unit when detached from tractor. We also supply the BIO-100 with an extended-width axle bracket, which can be installed with 2 bolts to better stabilize chipper/shredder on slopes; caster wheels then mount to the ends of this bracket. (leaving this bracket off results in a narrower machine that will fit easily through as little as a 25” opening).
NOTE: The chipper/shredders will chip both green "new/fresh" wood and dry wood; However, when chipping dry wood the chipper blade will dull faster and will thus need to be sharpened more often.
