Battery electrification of industrial farm equipment and truck transport is quite unlikely to allow the same scale of production that is feeding the world now.

570 Liters of diesel per day = 5,700 kWh per day. Even if you cut that by2.5 for the extra efficiency of electric motors with round trip losses you get 2,300 kWh per day for a large size farm machine. 12 Tesla grid scale 200kWh powerpacks per day to hot swap in and out. for just one tractor. We are going to need to start making a lot of wire to get all of this power around.

Nitpick is not the word. I just wanted to make clear fossil fuel is not essential for modern agriculture.

You calculate diesel by its total energy content, but the heat produced gets lost anyway. You should calculate the power you get at the axle from diesel under ideal circumstances, then factor in a loss because farm equipment spends a lot of time working under less than ideal conditions. It needs power to deal with heavy conditions so it wastes efficiency under lighter conditions.
Electric motors don't get much less efficient under light loads, and do not idle at all.

Then, your 200 kWh pack is quite small for heavy equipment. Tesla semis will have a 500-600 kWh pack. A combine could have a bigger pack than that.

Anyway, agriculture makes for just a fraction of global fossil fuel usage. Whatever equipment cannot be electrified could be powered by biofuel. There's no need to wind down farming efficiency at all.
