I'm trying to tackle my 300 feet of lawn with my electric mower, but I can't find a single 300-foot extension cord. I do have three 100-foot, 13-amp extension cords. Can I connect all three to safely mow my grass? I'd really appreciate any advice on this!

At that length, you'll want to ensure your cords are heavy-duty and equipped with locking plugs—they aren't cheap, but they're worth it. And trust me, dragging 100 pounds of cable is a real pain for an acre. Consider getting a battery mower instead if possible.
Have you thought about getting a battery or gas mower? A 13A extension cord is really quite thin for 300 feet. You might run into issues if you're drawing too much power. Plus, dealing with gas and storage at home could be a hassle if safety's a concern with kids around.
I’ll check the price on the battery mower options since those three extensions will cost me around $210.
If you're using decent quality cords, you should be okay for short bursts. Just run the mower for about ten minutes and then check if the cords are hot; if they are, you might be pulling too much power.

I looked into a battery one, but the battery lasts only about 10-15 minutes. With a whole acre to cut, I’m worried about running out of juice. Gas mowers aren’t ideal for me as I don’t have a garage and don’t want to store gas in the house.
