Twenty inches of bar on a 40-volt pack is an aggressive proposition, and Ryobi is straightforward about what it costs: the runtime figure they publish — over 100 cuts — is quoted against an 8.0Ah battery, not the 4.0Ah most owners have. Buy this one bare at $349 and budget for a big pack, or the saw spends its life half-fed. What you get for that is the largest cut capacity in the Ryobi range, 36 inches with a bore cut, and a 52cc-gas equivalence claim backed by full 3/8-pitch .050 chain rather than the low-profile chain on the smaller models. Thirteen pounds bare puts it at the top of what is comfortable to hold out at arm's length, so it is a bucking and felling saw rather than a limbing one.
Best for: Ryobi 40V owners with high-capacity packs who need to buck real firewood rather than clear brush.
