the OP wants to run a 20" bar in hardwood. Think a 7900 will pull it
Whats a CM? hey if I don't ask I won't know...:confused2::confused2:
A 441(CM)
A stock 7900 will easily pull a 30" bar in Yellow or White Box, trees in the past that needed 056 or 660 size saws at a minimum to deal with.
Box is a type of Euc and harder than concrete, it makes Oak, etc look like Pine.
