No. I had a plug-in electric mower once and did not like it because the blade was so thin to keep it light. The blade didn't hold up well, especially if one hit a root. Hopefully, the cordless mower holds up well and works well for you.

As for gasoline mowers, always buy no-ethanol gasoline and then add gasoline stabilizer to it. It makes all the difference in the world. I don't care that the manufacturers say that 10% ethanol is okay. Maybe until the warranty expires, but it will cause problems unless one drains the gasoline and runs the carburetor dry after every use. Ethanol attracts moisture which then promotes gumming up the carburetor. No-ethanol gasoline does not have that issue and if stabilizer is used, holds up well, even if it is left in the tank for extended periods. This applies for string trimmers and other 2 cycle engines that use gas-oil mix also. It really is applicable for gasoline powered generators also.

By far the best walk behind mower I ever had. I will never go back to gasoline, I honestly don't know why anyone would. Quiet, no gas to buy, no fuel contamination, no maintenance of any kind except the blades. Its so quiet I feel OK mowing at 7am when its nice and cool bc I'm not bothering the neighbors, 

I have a steep half acre to mow so I need self propelled. The mower runs longer than I do, I just put the batt in the charger when I take a break. I got the Ego string trimmer too. The auto rewind feature is fantastic. takes 10 seconds to install new string in it. First time I did it it was why didn't anyone think of that before, but you couldn't do it with a gas motor. 

I no longer have gasoline at the house at all except in my cars, my backup/rpod genny runs on propane, and all my power tools are electric. 

But for a half an acre in suburbia, absolutely its there. No reason for gasoline anymore. I have a nice electric chainsaw, slabbed up 3 large cherry trees this spring, no problem at all. If you haven't tried out the new electric trimmers and mowers and you're in the market by all means take a look. 

Have two EGO mowers and a leaf blower.  Love all of them...great the way the batteries work in any EGO product.  Ditto on the early-morning mowing...nice and cool out then.

The area around the house is 2-1/2 to 3 acres and is sloped enough to require a self-propelled mower. Can't do that yet with battery or corded, so we have a 36" dual-blade self-propelled mower we use for that. For the other 36 acres we use the tractor. I always add stabilizer to the fuel in the mower AND I run it dry every time I shut it down so there is nothing to gum up in the carburetor. We also brush cut along the driveway, which is about 3/4 mile long, so that is also tractor work.

The county hits it with a team of large Kubota mowing tractors, about once or twice a year. These guys have large articulating mowing decks with 'wings' that have hydraulics and they cut the 2-4 foot tall weeds on angled berms and culverts with no problems...but they are on some kind of contract with the county, and they are from Waco and...anyway....I need something that will work, in between the jobs that the 'pros' do once or twice per season.

The little cheap weed-eaters are just not enough hardware...I need something that is on a shoulder or body harness or sling, with a head that can be angled or twisted to get in and 'tear it up!'

Gonna cost money... I know that!

The slope to the south of our house is roughly 2-1/2 acres with a 45 degree slope (100% grade). It is approximately 24 hours of labor for someone in extremely good shape using one (or both) of our Stihl brush cutters. It is largely grass, but there are significant portions with Yellow Star Thistle, Italian Thistle, Bull Thistle, and Mustard. None of those can be cut with wimpy string trimmers. We use a heavy duty cord that is 0.155" diameter. We have to change line about once per tank load. A tank load will last between an hour and 90 minutes. The good news is it just needs to be done once per year if you time it correctly.

Next up: Julie Andrews in, 'The Sound of Mowing'...

I bet my local John Deere stealership has several on the showroom floor. I'll head that way next week.

When electric hits the point that I can pull that stump or split all that wood.. and still mow/plow, I'm interested. Well, cost comes into mind...

I'm at a kilowatt of solar and will not move further till it makes sense... 

I ran a residential solar company for many years. The two worst things we dealt with were (1) trees and (2) architects. Trees are really pretty easy, do a survey and the either cut down the offending ones or don't do solar. The architects were harder. They insisted in putting useless bric a brac like attic dormers and false gable ends on otherwise perfectly good south facing roofs. And they insist of putting plumbing vents and flues on the back roof even if that is south facing. 

Orientation isn't really the issue folks think it is. Generally, east or west facing arrays produce only about 20% less than south facing. We can almost always find a roof face that will work if its unshaded and doesn't have architectural junk all over it.  

Personally, I prefer ground mounted solar. I don't like ladders, and the electric code requirements are simpler for ground mounts. 

You can get a rough idea of tree shading impacts from Google Earth if you live in an urban area with detailed elevation data.
