Think someone mentioned the battery saw weights were with batt installed and b+c attached?
If that is true then totally understand why they show so heavy.
That was me. Yes, of course pro gas saws are all power head only, no bar, no fuel. The older (1990-2010) 50-70cc variants run about 1.6 to 1.8 kg/kW, with newer EFI saws sometimes running even lighter than that.
The battery saws from Greenworks list their weight with a 4Ah battery, even though they sometimes give performance spec’s with a 6Ah battery.
They do not state whether the given weights are with or without bar, but since they are sold pre-packaged with a bar, it seems reasonable to assume the weights
might be with bar installed.
Either way, even if battery saw weights are with bar, that’s not nearly enough to close the gap.
I find that the battery saws are not any heavier than the near equivalent gas chainsaws. Depends on the brand I suppose in some cases it might not be true.
Let’s look at hard numbers: The Greenworks 82CS34 has power (2.9 kW) comparable to any 55cc saw, comes with a 20” bar, and is listed at 7.8 kg, which
might include weight of the bar. Stihl 20” Rolomatic ES sprocket nose bars run right around 1.3 kg in standard weight or 0.9 kg in lightweight variant. But 55cc gassers will run around 5.0 kg without bar, so we’re looking at 5.9 to 6.3 kg, depending on 20” bar type. Fill it with 14 - 16 oz. of fuel mix, and you’re adding another 0.35 kg, so perhaps 6.25 - 6.65 kg at full tank.
If the Greenworks numbers indeed include the bar (not clear), and if you only use the 4Ah batter (never upgrade to 6Ah), then
the Greenworks saw is 25% - 32% heavier than a comparable Stihl gasser with an ES Light bar. If the Greenworks numbers do not include the bar, or if you upgrade to the 6Ah battery they actually used in the article that started this conversation, then the gap widens further.
