People do make such a big deal on electric tractors for some reason. I'll just ask, how long have electric forklifts been around? They work just fine. Heck, I have one from the 70's and had it for 30+ years. It used to run daily up until 10 years or so ago and now gets used like 3 or 4 times a year and it's a simple as connecting the Anderson plug, turn the key switch on and it's good to go and I don't even charge it as frequently as I should.
I agree with Fixastuff, the ones who complain the most are the ones who put the least hours a year on a tractor and could indeed do just fine with an electric tractor.
A Farmtrac 26G electric tractor was delivered on a small greenhouse farm a couple months ago to work the ground inside the greenhouses and to maintain the place. That's another great application for these tractors. Working in closed environments like greenhouses.
