Alot of states have emissions test for vehicles, what about lawn equipment?

every time the dude next door is using his weed wacker and lawn mower my house smells like exhaust for like 45 minutes.
in the winter, the snowblower does the same.

Yeah good point, what about farm/ranch equipment?? Chain saws for the loggers, or they should also make sure all older vehicles are safe for emissions. I think in the end there are lots of things that should be looked at :).....
I agree, at least for the professional lawn care people that run their equipment every day during the season the grass is growing. I guess the reasoning is that its easier to monitor because you get a sticker that goes on the windshield. It would be harder to catch you in your yard working with an illegal emission coming out of your equipment. BTW I use electric weed eater, edger and blower for that very reason. :)

emission laws exempt engines under a certain displacement. that include lawnmowers and leaf blowers, as well as hedge clippers and other small engine appliances. the other thing is that these engines are not run long enough to have any real impact on the environment, other than exhaust fumes.
Unfortunately not, and you are correct that those two stroke engines are very dirty and bad for the environment.
Lawn equipment is not regulated for emissions. People can however elect to use electric equipment, manual equipment, or a model that doesn't emit so much pollution. Weed trimmers come with different types of engines. The ones that don't use an oil/gas mixture don't give off the fumes like the others do. These cost more but it might be worth it to you for the sake of not breathing that stuff in and being sick from the odor.
Actually, while there are no inspections for individual units, there ARE pollution standards for this entire class of equipment -and they're strictly enforced and observed, despite what one respondent has said.

First of all, most equipment was, at one time, all based on 2 cycle engines; the kind where you mix oil and gas together. That method is inherently polluting, because the heavy oil gets burned up and becomes part of the exhaust. Furthermore, tuning such engines was neither really possible nor necessary. What is needed is RAW power to apply under conditions that are so variable it is difficult to build equipment at reasonable cost that will self adjust to the circumstances. Nonetheless, the power plants are all built to use unleaded gasoline, and the oil additives are refined to keep pollutants as low as possible. And the engines themselves are built to run HOT, so they are efficient. These controls are not ideal, but they are the best that can be done -at reasonable cost- given the technology as it is.

You may have noticed, as well, that no lawnmower these days has a speed control, whereas at one time they ALL did. They are basically either full speed or NO speed. The reason for that is that the speed at which they run assures that the least contamination of the exhaust will occur. Actually, the mower doesn't run at FULL power all the time, because there is a reserve for heavy mowing in high grass, leaves etc. The idea here is that the mower will self-adjust to the situation an run at optimal speed in most all conditions. All of the EPA inspired.

You may also have noticed, that except for the smallest engines (weed wackers, chain saws, etc.) more and more equipment is based on a 4 cycle engine, which costs more than a 2 cycle, which is why its tough to find a mower for under $200 these days. The 4 cycle engines carries oil separately, just like your car, lubricating engine parts rather than making the gasoline itself "slicker." The 4 cycle combustion process is inherently less polluting than 2 cycle. Pound for pound, 4 cycles are less powerful than 2 cycles, which is why the engines themselves are bigger and heavier, and generally mounted on wheeled equipment which is either self-propelled or pushed and pulled around -as opposed to being carried.

That leaves the class of 2 cycle small engines used for chain saws, small tillers, weed wackers, etc. These DO have speed controls, because they are not always working against a load: resistance of timber, garden soil, weeds and brush. Thus, if they had just ONE speed, which would need to be the fastest so they could get through the tough stuff, they'd run themselves to destruction when NOT so applied or need to be constantly tunred on and off. Even so, many of these engines have passed EPA certification -the Red Max, for example.

Because there are millions of these little demons balsting away out there in yards and driveways across the world -and still many that are old and not compliant with current regulations, you have some real stinkers in the neighborhood, as you've noticed. And owners tend NOT to maintain them -they just keep adding gas and oil and doing little else. Obviously, the sheer number of them make it difficult if not impractical to individually certify each one. Therefore, the EPA has attempted to control them as a CLASS, at point of manufacture; same as Energy Star ratings for appliances, TV's, etc.

And, as a matter of fact, some commercial machines MUST meet EPA regs or the landscapers and maintenance people won't be allowed to bid on big jobs.

So...what can YOU do? If you think your neighbor really is fouling up the place, call your health department (who locally enforces EPA regs) and request an inspection and survey, if not for the stink, then for the noise. File a complaint. A white-lipped inspector will show up with various gadgets to document the problem, and probably attempt to get you and your neighbor to agree that the neighbor will only fire up his equipment when enough wind is blowing around to disperse his bad smells. Usually, that is what they try to do, as opposed to some fine or penalty -unless the situation is REALLY bad.

This may not be the answer you wanted, but it is what the government has come up with so far. I hope it helps set some context for you.
