As a very broad rule-of-thumb on Lawnboy 2-cycle mowers (all)..the Cast Aluminum decks are the premium line, the Steel decks are the big-box store lower priced models. Of course even a steel deck Lawnboy was more expensive than the competition steel deck mowers. The engines and-if self propelled-the transmission was the same on both types, and varies with the year produced. The so-called "commercial" lines often added bigger fuel tanks and more robust wheels, steel instead of plastic. I think the Scamp was the lowest priced Lawnboy during the time it was produced. All the engines are the same regardless of what type of deck they are on. A DuraForce, a "F" or "V" engine would be the same on any deck lawnboy put them on, and with any transmission. So, for example you could have an "F" engine on all the various Lawnboy models made during the timeframe of "F" engine production, from the cheapest to the most delux, but the difference was not in the engine, but rather the deck, wheels, and gas tank size mostly.
