When professionals need to fell large trees, in large quantities, they reach for the saw they know has the power to get the job done —the MS 661 C-M.

Other features include a long-life filter system using HD-2 filter elements to provide longer run times between maintenance, an ElastoStart™ handle, and a high output adjustable oiler.
