Yeah, I guess for some farms that size of tractor is a utility tractor. For field tractors used for tilling, planting and harvest, battery powered tractors don't make sense, there you need to make 200-300-400 HP for 8-10-20 hours at a time often out in the middle of nowhere and the tractor may not get near a plug in for a couple weeks... Liquid fuels make sense for that duty cycle and location...
The electric tractor makes sense for some farms as a utility tractor, which spends lots of time idling, warming up, etc... My dairy farm buddy uses his utility tractor around the barns, and I asked him how many hours he puts on it? Around a 1000 a year which sounded like a lot to me, "you drive it around for 3 hours a day on average?" He then said it spends about half that time idling, warming up, or waiting for the skid steer to fill the manure spreader, or just running bales or wagons in from the fields, and running to the end of the round bale tube to grab some hay, so he's maybe in the seat for a bit over half those hours... There his 100hp tractor uses maybe an average of 30hp or less for all its hours and probably never runs for a full day straight without going back to the farmstead. Probably it would be a bit annoying to have to park it near the charging plug at lunch, but diagnosing tier 4 emissions equipment on a tractor out of warranty can be very annoying too!
