I have a Stihl 362 and a 271 both are pro grade (which is worth doing).
You’ll notice that there are 3 different chain thicknesses on saws, the smallest is just about worthless so stay away from those..
the second wide vs. the 3rd is a HUGE difference,
At the end of the day a 440 is the biggest saw and it’s for cutting the stump (huge [bleep])
the 362 is for cutting huge branches, and the trunk - but NOT limbs...
The 271 (MS271) is a lighter strong saw used to cut the limbs to leaves.
Okay,...so what chain thickness do you recommend for 10' diameter cuts and under?
3/8 x .050
The saw you buy will generally determine the chain size (don't confuse that with length--the bar length will determine the chain length). Most saws in the 50-60cc range use the 3/8 x .050 chain.
