In this video, I talk about some of the main differences between 2 stroke and 4 strokes small engines for powering lawn care, equipment, and machinery. There's a reason why lawnmowers almost exclusively, use 4 stroke engines. And why small handheld equipment almost exclusively, uses 2 strokes over 4 strokes.

Important note: I meant this video to be a general overview of the differences between 2 stroke and 4 stroke engines in the small engine world, and why they are typically used in certain applications. I was not trying to say that only 4 strokes are used on lawnmowers, and only 2 strokes on handheld equipment. There are exceptions that work quite well, as I mentioned in the video.

I’ve got a Troy-Bilt JumpStart TB625 EC weed trimmer that’s actually a 4 stroke, but it’s certainly not the norm for trimmers. That one has the ability to swap out the end for an edger as well which certainly can be handy. At one point my brother had about 30 different weed trimmers he had collected up to work on / people gave him / he found, but this was the only one he found that was a 4 cycle like this (as far as I know). It’s certainly on the larger side but I feel Iike I’ve used bigger / heavier duty trimmers than this before. It also does have an optional sling strap to help take off some of the weight but I haven’t always used that with it.

Honda makes a 4 stroke string trimmer that is well regarded. And the Stihl 4-Mix trimmers are 4 stroke engines but they use a 2-stroke style fuel/oil mix that lubricates everything the way a 2 stroke does.

Cool, I have never seen a 4 stroke trimmer in person, but I have definitely heard about them.

the only reason Lawnboy quite selling 2 strrokes was due to stricter emissions they were light weight and ran forever as long as you didnt forget to add the oil to the fuel .

Interesting, it would be cool to get one of those.

A popular 2 Stroke at one time was the Wisconsin Robin on Snapper Lawnmowers. They were offered on other applications with at least 4 Hp and higher.

Interesting, I have a Wisconsin Robin powered snapper but it is 4 stroke.

Lawnboy also made a 2 stroke mower in late 80’s and early 90’s

The 2 stroke Robin powered Snapper was awesome! Great power and very little maintenance (no oil changes) and they lasted for years!

@@Differentthings2006 They actually had both available over the years.

@@jamiewarner9101 not quite true. Lawn boy made mowers all the way from the early 50's to the mid 2000's. Engines include: Iron horse 'a' series engines, Iron horse 'c' serires engines, OMC 'c' series engines, OMC 'd 400' series engines, OMC 'd 600' series engines, 'f' series engines, 'm' series engines, 'v' series engines, and finally 'e' or 'duraforce' engines. Of course there are many before the 50's on rare reel mowers made by omc, but those are hard to come by and don't have a lot of information about them out.
