Weight. Cost.
Micro fuel injection systems are being introduced on small engines now. (Just looked at a snow blower so equipped)
That should go a huge way to cleaning them up. Also catalytics. They are tremendously versatile on a host of equipment in extremely demanding applications.
Battery power will have to come a long way to replace them.

Depends on what one means by pollution. Excluding CO2 and H2O (these are natural products of combustion), the other gases like nitrous oxide, CO, and unburnt fuel are considered pollutants.
Cars have catalytic converters, which burn up those nasties and emit very little other than CO2 and H2O. Small engines don’t have catalytic converters - or the combustion mixture controls that modern fuel injected engines have. As a result they emit, raw, what exits the combustion chamber.
When they want to ban your lawnmower, they talk about NOx
Most people, these days, are worked up about Global Warming, which has nothing to do with lawnmowers. It has everything to do with the amount of fuel burned, which for lawnmowers is very little.
Your lawnmower produces a minuscule amount of CO2 compared to your car. So, when it comes to talking about lawnmowers, we are going to ignore CO2 and worry about smog-forming pollutants and particulate, instead.
I did ditch my gas mower for an electric battery one. It was on it’s last legs and a pain to keep running. Got the electric on sale in fall after the season was over and they were dumping inventory.
No gas, no oil, no filters, no gaddam pull cord - pull cord - pull cord... One button push, battery charge is good for an hour. I have to admit, it’s very convenient.
Because of the Yuge push/lobbying by electric mower manufacturers I presume. Wizards of OZ don’t want you to see behind the curtain though to see what actually powers them:-)
That’s why I take my grandkids for rides on my lawn tractor.
Fun and emissions in one package.
Cars and trucks have sophisticated fuel delivery systems that allow the fuel injectors to deliver precisely the right amount of fuel into the air stream to burn cleanly and efficiently. They also have a catalytic converter to take care of most of the NOx and CO emmissions. So to get a lawnmower to run as cleanly and efficiently as a car engine you need 1)a catalytic converter, 2)mass airflow sensor, 3)temperature and pressure sensors, 4) electronic fuel injectors, 5) Oxygen sensors, and 6)a computer to run it all. And this is a minimum.
The statements are based on different measurements of “pollution”. In one CO2 is not included, in the other, it is.
CO2 “pollution” is determined nearly completely on the volume of fuel consumed over time. Automobiles burn far more fuel than lawnmowers or golf carts when measured for a year in a country. Thus, by the CO2 measurement, they produce far more “pollution”.
However, when measured by other methods, looking at nitrous oxides, CO, and unburned hydrocarbons, automobiles use three-way catalytic converters which eliminate nearly all of these pollutants. Thus, in comparison, your lawn mower, or any other internal combustion engine, with no three-way catalytic converter, produces much more of these.
Thus, the authors of this lie are comparing apples to horse manure.
> CA wants to ban all gas-powered lawn tools
Gotta keep the demand for illegal immigrants to boost Democrat votes.
COOL! Where can I get one?
I’ll run it all day for Earth Day!
Maybe their ultimate objective is to ban personal electrical generators for the home.
I don’t understand the reporting, but battery-powered lawnmowers are a LOT quieter, are cost-competitive, and you don’t have to worry about keeping a gas can or getting a blast of pollution in your face. I really don’t know why anyone would buy a new gas-powered lawnmower.
CA wants to ban them so as to increase their power over the public. It’s one thing at a time. Straws. Plastic bags. Natural gas for heating.
Do not doubt that they are targeting the private car that is powered by a gasoline engine. They WILL, given enough time, force us to ride in a community vehicle that runs on electricity and is monitored and controlled by a Central Computer System.
At home I use a Ryobi 40V battery-operated mower, not because of silly climate change BS but because I hate the smell of gasoline that I’ll invariably spill when reloading.
The battery unit is more than good enough for the 7000 sq feet that I have to mow, front and back.
It’s like the light bulbs all over again
There’s no need to get the government involved when there are technological solutions coming.
For most postage stamp suburban lots less the an acre, battery powered lawn mowers are already superior to gas ones. No smelly gasoline, no oil changes, no pull chains, less noise.
Don’t do anything and electric mowers will replace most gas powered ones just like LEDs are replacing most incandescents.
For larger lots and lawn care contractors they will still rely on gas powered lawn tractors, but who knows, technology is improving in those areas also.
Is this article fat shaming congress :D
What will drive liberals crazy is to ask why all of the climate refugees from Latin America mow dead yards all winter and help to kill Mother Gaia. Or blow the leaves from one yard to the other for something to do. I see it all winter long in Texas.
I’m not proud of it, but my lawnmower produces as much pollution as 43 cars. 1985 POS, but get the blade sharpened every year and it keeps working. Never have changed the oil...ever! It likes oil.
