Perhaps more so than with most things in life, you get what you pay for in lawnmowers. There are just so many (insanely) cheap rotaries that do a faultless job for several years, and then fall to bits.
As for the decks - pressed steel - stamp a blank from a roll of steel, place in press, whack, job done, although it will be painted/coated. Cast aluminium or moulded plastic, both way more expensive options.
Really the fault of the actual engine???? More likely a fuel leak that reached something hot. I have the occasional fire when the grass has had lots of light dry stems in it that fly everwhere and get stuck behind, usually, the exhaust.

our old rotary went up in smoke.
