Putting Lawnmowers away for winter ? (How To)

I have read and heard conflicting advice when putting lawnmowers away for the winter.
Some suggest having a full tank of gas and add a stabilizer , Others suggest emptying
the gas tank for winter storage.. Any thoughts on this ?

Pros and cons of each. I store all my small engines with premium gas w stabil. I find it keeps gas related hoses and gaskets pliable and free from dry rot. In the spring that gas is dumped, fresh stuff put it. Oil gets changed in the spring too.

I learned many years ago to scape the underside of the mower deck and get it clean. Leaving old grass stuck to the underside can cause rust to start and weaken the deck.
As far as gas, I leave a small amount in the tank with stabil, and it always starts on the first or second pull in the spring, don't believe sitting for 3 or 4 months with gas in it hurts anything. I do change oil before putting away though. That prevents old oil with any contaminates in it, to do any damage to the engine.

I clean the bottom of the deck and paint it with a thin coat of used oil. Take out the battery and put it in the house. Then just park it for the winter. In the spring I start it up, never a problem, run it till warmed up, shut down and change oil. It must be working, mow an acre and a half each time and it's now 15 years old. Gas going bad is a strange thing. I've had engines that just refused to fire after 4 or 5 months. Change the gas and they fire right up. Then I've got chain saw gas that works in the saw and it's five years old.

Gas going bad IS a strange thing. I add sta-bil most but not all of the time. I put all of my seasonal toys away with the gas that's in them at the time and I've never had any issues in over 50 years of doing this! Only one time when I stupidly had some gas with the dreaded ethanol in it in a snowmobile for the last ride. The following winter when I went to start it - nothing. To make a long story short, it had accumulated a LOT of water so I had to drain it all out and add real gas and then no problems. I usually buy some regular 87 octane, no-ethanol gas in Oshkosh on the way up north (Townsend) and I also use it in all my small engines down here in New Berlin. I also have used gas 7 or 8 years old in chain saws with no issues, so who knows? (Your mileage may vary) I also use the cheapest 2 cycle oil!

Exactly. I do the same as you when storing anything with a small engine, and that is, nothing. As long as you have ethanol free gas in the tank, no problems. If you ever listen to hot rod owners and the use of ethanol gas, you will learn that it eats away at anything made of rubber and aluminum in the carbs. There's a very good reason why it is strongly recommended that you never use fuel with ethanol in your airplane. It's one thing when the engine stops on the road and another thing when it stops in the air.
