DO YOU CUT WOOD IN DIRTY OR ABRASIVE CONDITIONS?

If you cut abrasive woods such as railroad ties, or if you cut in the following kinds of locations: sandy areas, partially logged areas after skidder extraction, fire-damaged areas, or any place where the wood has become dirty

™

– then you may prefer the MultiCut

versions of Oregon® chains. MultiCut™ chains have extra-heavy-duty chrome plating applied with an advanced plating process to withstand these kinds of tough dirty conditions. Contact

Oregon MultiCut

or your authorized Oregon® distributor for further information on
