How many horsepower is a Briggs & Stratton 190cc 675ex Series engine?
It seems as if every time I want to use a lawnmower, I have to get it tuned up. (I exaggerate. In reality, I think they're hard to start because gas only lasts a few weeks before it 'goes bad' unless I remember to put stabiliser in it.) So one of the Craftsman 6.5 hp mowers in getting a tune-up. Since everyone is having their mowers maintained right now, I've waited two weeks to get it back and I likely won't get it back until sometime next week. So I borrowed a mower from the shop.
The SO has said on several occasions that I need to get a self-propelled mower. The yard isn't exactly level, and the back yard never really dries out in this climate. Turns out, the mower I borrowed was a well-used self-propelled Snapper of 6.5 hp. (I think it used the same Briggs & Stratton engine as the Craftsmans.) I have to admit, I liked it. So I'm browsing self-propelled mowers.
One of these mowers uses a Briggs & Stratton 190cc 675ex Series engine. I wanted to know how many horsepower the engine is, but it's not in the specs. I went to a website that sells this engine, and it says: Rated Power (HP): Manufacturer no longer rates this engine by HP. Apparently it has 6.75 ft/lbs torque. An online calculator says that 6.75 hp at 2,600 RPM is 3⅓ hp. That seems a little anemic, especially considering that the wet grass in the back yard chokes the mowers with double that. Is the calculator correct?
