I had a lawn mower wheel height adjuster stuck hard a week or two ago. I bought it off a neighbor for $20, so I expected a few problems. I fixed it with a screwdriver and a hammer.
I’ve had such success with Marvel Mystery Oil in my lawn mower than I’ve gotten questions about Marvel Mystery oil in a snowblower.
Yes it will work. It will work in any gasoline-powered yard tool. And I would expect the same results. It works in small engines, it works in cars, and some pilots even use it in airplanes.
It’s very easy to winterize a lawn mower and I definitely recommend doing it–nothing gums up a mower like sitting in a garage for five months with a full gas tank. Taking fifteen minutes out of your day sometime in November can save you lots of heartache, and maybe 50 bucks, come spring.
Last year I didn’t winterize my lawnmower at the end of the season. Shame on me. So I took some extra precautions this year to avoid a $50 lawn mower repair, and got away with it. Here’s what I did.
An article on Lifehacker this week explained a lot about how I initially became a computer professional. Its advice was to fly by the seat of your pants, try things without guidance or manuals, not be afraid to fail occasionally, and learn before you go to sleep.
So when I spent many nights in my late teens disassembling and reassembling obsolete IBM PC/XT clones to learn how they worked, I was unwittingly doing all of it right.
I needed to change a lawn mower blade this weekend, which meant I had to remove the stubborn old blade first. That proved to be a challenge, but not an insurmountable one. I learned the secret of changing a blade without hurting myself, and without a torque wrench, even when the stubborn bolt doesn’t want to turn.
To remove and replace a lawn mower blade safely and easily, you need a length of 2×4 board long enough to stand on, a small plastic pan, the biggest socket wrench you can find, and a socket that matches the bolt on your mower. If you don’t have a socket wrench, you can use a regular crescent wrench, but you want the biggest one you can find. Longer wrenches give more leverage, and you need lots of leverage to free a stuck bolt. Read more
I’ve always hated my lawn mower. But once I started using Marvel Mystery Oil in a lawn mower, and putting synthetic 10w-30 oil in the crankcase, I’ve been much happier. It makes me feel like I discovered one of the secrets of the universe.
While you’re at it, check the air filter. You’re supposed to change that every year, at least. The combination of a fresh air filter, Marvel Mystery Oil, and synthetic oil gives me easier starts and smoother running.
