I'm planning on buying a new lawn mower shortly with Spring coming sooner or later.
My question is, today's mowers are not rated with a horse power rating ? Everyone I look at has CC's on the motor. Is there an easy CC to HP conversion ???
Thanks

 

CC's could convert to CI but not HP

 

Thanks for the speedy reply TomsHHR.

Then if CC's go to CI is there a way to go to HP from there ??

Thanks

 

well, just an example would be a 50cc engine might be 5 hp in one version but it could be 7 hp in another version..

Try looking at briggs and stratton motors or techumseh mowers and compare.

 

Thanks

 

What kind of mowers are you looking at? Most consumer-grade mowers still use HP ratings.

Ok, weird. I just went to Sears' website and all the Snappers have 190 CC Briggs engines on them. Those same engines make about 6-7 HP on the Craftsman mowers, so that's probably what they're making on the Snappers. Then again, I know they've had to do a lot of modification to the engines for emissions standards, so power may be down to 4-6 HP now that some of the ratings are for torque.

 

I can't answer your Question to what CC's Equal. Personally it was stupid to change when everyone know's HP. Then again that's some Moron in a office making a decision.

Anyway i would go with a Craftsman with a Briggs Motor. They seem to last forever and when they break are easier to fix then others. Biggest complaint people have is they don't like to start in the Cold weather. Simple fix Mobil 1 fire's every time.

Mine is going on 10yr's old. Which reminds me i need new tire's.

 

There was actually a complaint (lawsuit) filed against several mfg because they rated the HP at a higher rpm than the mowers actually achieved in operation. Maybe that has something to do with the lack of specifics on the HP. Stick with a brand you like and keep in mind you get what you pay for. My latest favorite is Honda, and I love it, but it was expensive relative to my past mowers.

 

Honda and Kawasaki probably have the quietest, easiest to start engines on the market and the mower will rust around the engine before it dies. But if you're not going to do the yearly maintenance or spend the extra money and want something to bust around for four or five years, buy a Briggs. I live in a town where one of the major employers is Briggs. While most of their employees use their paychecks to buy meth, they just get more productive the more they tweak out.

Avoid Tecumseh like the plague. I used to work for Sears selling mowers a few years back and their lawn mower engines are crap. Specifically, the carbs seemed to clog every season, which now results in a complete carb replacement, and the lower HP models had a tendency to throw rods out the side of the engine case. Tecumseh makes a great electric start snow thrower engine, but it's set up totally different for the winter.

 

CC = cubic centimeters or the volume displacement of the engine. No way to convert CC to HP. Think of any car engine : a 350 CI chevy engine can have anywhere from170 HP to 350 HP all depending on the internals and carburation.
