I can not see it running all by itself in field work. Lets say the rake has a flat tire or sheers a pin and quits working, or what would happen when hooked to a disc mower and the mower picks up wire or plastic sack and clogs the mower. Will that thing stop or keep on dragging the broken equipment around.I watched the video and - electric motor and all that goes with it aside - I really liked some of the features. I'd love to have a tractor that could be programmed to mow or rake the fields. The "follow me" feature was really cool as well. And they said the tractors would run from six to ten hours per charge. At my age I'm very rarely on one for more than ten hours. They way they described it, about all you'd have to do is open the gate and the tractor would mow or spray or feed your cattle. If true, that sounds pretty good to me.
Now, how they perform in single digit temps or when you have mud up to your knees....who knows. And the real question is....Can they back a trailer?
