I don't know how this relates to your question but when I read the subject header it made me think of this.
A few years ago I was watching the Today show and they were showing some new lawnmowers and one of them was a John Deere with an 110 volt A/C outlet built into it. I don't know how long this feature has been around but I thought that was a neat idea. Dad's new John Deere does not have this outlet. Maybe it's just available on higher end models or is an option. Like hour meters on Husquvarna riding mowers.
I got the bright idea of seeing if I could use an inverter on my Snapper so I could power my electric tree trimmer, and chainsaw. It didn't work.
I think the inverter was rated at 1000 watts. I'm not sure if the mower's engine wasn't powerful enough to power the inverter or the inverter didn't have enough power to power the tree trimmer. I do remember testing this same inverter on an old 13" tube type TV and you know those things have to pull a lot of power, surely if it could power a tube type TV it could operate a small tree trimmer motor.
Three years ago we had a wet snowstorm before Christmas which knocked out power and a lot of trees and to get my chainsaw just to get out of my driveway:

I live about 800 feet off the road and did not want to string together a bunch of extention cords and possibly create a massive power drop by the time I got down to bottom of the hill. I loaded up my 3500 watt generator in the back of my small yard wagon and pulled it to the bottom of the hill with my lawnmower and powered my tree trimmer with it. It was quite the setup!
