Speedy I doubt there is any trees left that need a saw that big anymore, and if they were that big you certainly would not be allowed to cut them down

Wish they would hold one in NSW within acceptable driving distance of Newcastle or Sydney.
I love old chainsaws.

Good post there, speedy.

These were the 'first generation' of chainsaws, back in the 1950s; they were 'two man' operation, as the engine had to be kept upright, due to the float type carburettor. Some models were built for sawmill use, with 3-phase electric motors, and bar lengths up to 8 feet, at least!

These petrol powered units most often had a gear drive to the chain drive sprocket, so as to allow the bar to be rotated to the horizontal plane, for falling cuts.

Tillotson's invention of the diaphragm carburettor in the 1950's was the game-changer for chainsaws; it made the one-man chainsaw a reality.

It did take a few years for really workable lightweight chainsaw models to be developed though, so the early 1960s was when the one-man saws really took off here.

I got one dead one on the back my property that had a 48 diameter. And I found one that was over 72" while hunting. I worked a over 8 foot diameter Bodock (Hedge Apple) that someone had dumped in a landfill for firewood and lumber. A shame that someone had to cut it just for a parking lot.

What's the biggest cubic capacity for a one man operated chainsaw?
I got a gardenline 46cc model from Aldi at 1/2 price for $80 at Aldi last year. I have used it once so far briefly to prune a couple of branches.
It worked alright.

Well, the largest capacity model in the current Stihl lineup is the MS880; 121.6cc.

But one of their past models [a mate of mine owned one of these - it was huge] was the 090; 137cc.

Its weight [~14kg] made it really awkward to use for falling cuts; it was great for cross-cutting the felled trees though.

Apparently there was also a limited-production 159cc version of the 090, sold in small numbers only in Oz and the US.

On YouTube there is a video of a 1970s Dolmar with rotary engine. Sounds the same as any chainsaw when it is revving but when it idles a Mazda Capella comes to mind.
