This is STIHL's MS 461 R and is a great all-around professional forestry and tree care chainsaw. With the same power and weight as the MS 460, it offers up to 20% less fuel consumption, meaning you can spend less time refueling and less money on fuel. The durable chainsaw also features a wrap-around handle for use in multiple positions for felling or limbing with hands in the proper positions. The heavy-duty HD-2 filter element provides longer run times between air filter maintenance.
