What kind of engine did the lawn mower have? All together now: BRIGGS AND STRATTON. That was the gold standard, it seemed. A critical selling point. For good reason: B&S specialized in lawn-mower engines, having apparently perfected a motor that could run without oil, covered in grass clippings.
According to their site, the company was formed in 1908 when an inventor named Briggs made a deal with an investor named Stratton, bonding them down through history. Anyone who's ever yanked the cord to get the damned thing to start can't think of one without the other.
They'd be pleased.
