Lawn mowers at least have four-stroke engines instead of two. Although, as you say, vastly more prevalent.

- toxik 6y agoHuh, I thought most of them were two stroke.
- Spooky23 6y agoNot for a long time. My cheap Walmart Murray was like $75 and is a fairly efficient four stroke, but is incredibly weak with the emissions tech and awful engine!
- toxik 6y agoI guess it’s a question of where you live. I meant the actual lawnmowers people use rather than what is on the shelves today - I have only seen oily old two-strokers around me. Also I thought low power gasoline engines were more efficient, but I guess they tend not to have any catalytic converters
- bostonpete 6y agoAll two-stroke engines require a gasoline/oil mix, AFAIK? I've used a dozen or so lawnmowers going back 40 years and don't think I've ever used one that required a mix...
- toxik 6y agoThat’s correct. I had a scooter in Asia that took oil in the fuel port just a couple years ago.
- ip26 6y agoI'm not certain, but I think the inconvenience of premix in two strokes tipped the market to four strokes mowers.
- AmVess 6y agoThey are 4 stroke, but they put small mufflers on them. Electric lawnmowers make a lot of noise, too. Not as bad as the droning of a 4 stroke at full throttle, but still noisy. I long for the day we ban lawns. Do that, and lawn mowers and weed whackers would vanish overnight.
- UweSchmidt 6y agoMy neighbor started a new lawn. The amount of water he has been using during the last few weeks with this automated sprinkling system is staggering. There should be a more natural and robust solution, some mix of weeds and small flowers that's also walkable, but also gives bees and other insects a place to live.
- ip26 6y agoI'm big into water wise landscaping, but there aren't really any species of groundcover that are both highly tolerant of foot traffic and also very water thrifty. Mostly shaded bluegrass actually uses less water than full sun buffalograss. (And buffalograss can't handle shade) So tree plus grass is actually pretty water thrifty as well as keeping your house cool...
- morsch 6y agoDepends on where you are. Lawnmower density decreases as population density increases. Scooter density is the other way round. I'd ban them immediately. The noise and air pollution is insane. Have the government co-finance replacement electrical scooters if it helps.
