And they're quieter! God I wish my neighbors all had electric mowers. Sometimes it seems like they're invited to all the zoom meetings I attend.

If you never mow and grow insect friendly lawns...you wont ever have to buy a mower...fuck lawns.

My next mower will probably be a lawn service

Jokes on you, I never did most of that anyway.

Also still got the gas can from pre covid.

I expect they do need lubrication from time to time. I just bought an electric mower this year and it's pretty low power, so I predict that any amount of additional friction in the system is going to be too much.

I've owned a car like that. Drove that thing for years until the driver's side door fell off and I parked it.

I'm not sure you can even buy a two stroke lawnmower. Snowblower, maybe.

Yes, you need to have oil mixed with the gasoline in a two stroke, because the area under the piston (where the crankshaft is) creates the vacuum on the upstroke to draw in the next fuel charge. Lubrication of the crankshaft bearings, then, must come from oil that is in the gasoline, either by premixing it, or from an oil injection system.

A four stroke, on the other hand, uses the top of the cylinder, above the piston, to draw in the next fuel charge through an intake valve, and the area underneath the piston is bathed with oil. Over time, that oil (including its additives) breaks down and loses its lubricity, and must be changed for fresh oil.

Most lawn mowers are 4-stroke.

Look at buddy over here with the 1960s lawn boy

Never seen a two-stroke mower...

Only for some engines. Make sure you read the manual and the cap.

Sharpen/replace the blade. It's cheap and easy to do, and it will cut like a brand new mower.

Also, this is a PSA that you should sharpen your shovel. Makes digging way easier.

I also solved mine but by never changing the oil.

Flipping it over is often the correct way to drain the oil.

I wouldnt say most are two stroke. In fact most mowers available for purchase at your local hardware store are going to be 4 stroke if not all of them. 2 stroke lawnmowers are a thing of the past. Everyone wants 4 stroke and self propelling now.

Most mower engines are absolutely not 2 strokes… they are 99.99% 4 strokes.

Now strim trimmers are maybe 60/40 2s to 4s.

Too hard! I just use it until it explodes. Still lasts about 10 years.

Genuine question as I haven't actually thought about this, how does that work when you don't have a winter? Where I live it doesn't get below 40° ever, or above 85°. Those are literally the overnight low in Feb, and midday high in Aug/Sep. Do I still need to drain, or just treat it like changing the oil in my car? I.E.: Every 6 months or 3500 miles, whichever comes first.
