This is a “top handle” saw, which is typically used by arborists while climbing trees. Climbing saws are built for professionals who may cut many hours per day, every day, rather than homeowners who may use a saw for a few hours 3 or 4 times per year. Also, because they are intended for use while climbing they are as light as possible. Light + tough + durable + powerful = expensive.
I comes with a 3/8 low profile, low kickback chain.
The dry weight for ECHO's CS-271T is, 6.6 lbs.
Hi Michael! Thank you for your inquiry. All of ECHO's top handle chain saw models, CS-2511T, CS-271T and CS-355T all have a ring on the back of the saws.
Even if you could it would be underpowered for a larger bar.
Hi Joe! The dry weight (without the bar and chain) for the CS-271T is 6.6 lbs.
Hi Homeowner! The CS-271T only accepts a 12" bar and chain.
