In 1977 an old working chum named Jim Furgusson sold me an old relic Homelite for $35.
It run, and it had a 60 in bar with half inch round chain, a 2 speed transmission and no muffler.
I fell only one tree with it. A 7 foot Monterey Cypress. Local traffic was stopped during the grand finale.
I had to drop the transmission low gear to finish the back-cut. There was a 3/8 steel spike in tree. Cut right through it. Not straight through but at a diagonal.
Made 500 bugs on that tree, and 3 months later I sold the old Homelite back to Jim Ferguson for $35 bugs.
Having no muffler the blast of that saw echoing off the trunk of that tree, while leaning on the saw to cut through that spike killed my ears.
But it was a glorious ending.
No clean up.
