Farms would have DCFC service if they had battery equipment. We're not talking about using battery tractors now, with existing infrastructure, we're talking about the future when such a thing might exist, and the practical infrastructure that might support it.

*and came up with approx. 116.683 kWh/hour load.

If we're looking at an autonomous,GPS-facilitated unit,operating continuously,24-hrs/day,we'd be looking at around 2,800 kWh/day.
A towed,'AG-PACK',2-wheeled trailer 'tender',with 5-Tesla Powerwall-2 units,At 3,701-pounds would suffice to provide enough power.
One operating,and a second,which with a 350kW charger,would come to charge in 8-hours,during off-peak demand,at discounted pricing incentive.Or during mid-day solar farm peaking,when renewables may have to be curtailed,due to insufficient demand,as is experienced in San Francisco,California' summers,where they lose about 850-million EV miles equivalent.

The numbers may be a bit loose,but hopefully in the ballpark.

Yeah, but where did you derive the average power/fuel consumption? That info isn't readily available as far as I can tell, and I can only find peak HP specs from manufacturers. That's not a useful metric since equipment is rarely at peak power output.

I had browsed farming forums to see what farmers were reporting for diesel consumption per hour. It was low enough that the equipment could run for days without refueling.

I'd like to see more of the work shown if you don't mind.
