Nothing about EVs is all that economical - today. The tech is new. The EV economies of scale are a fraction of what exists - today. The Infrastructure to provide large scale, stationary or mobile charging is not there - today. To be sure the battery weight issue is easier to to solve with a lot of ag equipment (exclude low ground pressure applications perhaps). Farming is all about logistics, so field swapping packs is just a thing.
