Lawn mowers are small. But we operate them only in one place. So, pollution happens only in that place. I think home owners should be the one complaining. Did your EPA conduct survey among home owners? Just wondering
Air moves. We have to be as conscientious as possible. To say something is just our backyard isn't accurate. Even small things combine to be big things.
I definitely agree that every little bit all combined can make a big difference. Some people don't think that global warming and its effects are real. I think there is too much science saying otherwise.
I can see regulating new equipment as it's sold, but how are they going to regulate all those mowers (and other lawn equipment) that are out there, chugging away with their old engines? Will they have incentives for ratting out your neighbors?
No ....
just like it has always been ... old stuff (and people), eventually get replaced with new... It will take care of it self, just takes a little time... and that is what it's all made of... Time. :smile:KennyV
Yeah. Sometimes I think small. But dirty air from many small mowers is a big issue when taken together. There are many lawn mowers in America and the world. How do we make smoke from small engines clean? Filter is ok? How about carbon monoxide?

The thing that gets me is the fact that lawnmower engines are getting bigger. What use to a 3 hp push mower is now a 5-6 hp. Riding lawnmowers used to have 10-12 motors for a 42-48 inch deck now have 22-26 hp engines. I can't believe that an old 10 hp engine creates more emission than a new 26 hp engine on that rider. And the older engines had more torque than the new ones.

The faster you mow the lawn........Speed and width the less pollution and motor in good repair.:biggrin:
You got that right...........todays Horse Power is actually Pony Power...........Remember the saying.....There is no substitute for Cubic Inches..............better a Lugger than a Screamer.

Todays engines use a shorter stroke with a light weight piston than engines built 20 years ago. Some of todays pistons don't even have a true skirt. older engines used a longer stroke to get horsepower so they had a higher torque output.
