I suspect that agriculture, with its well-defined fields, repetitive motions, and a healthy disregard to the exterior, would be easier to convert to electricity. If refueling a tractor is just removing one battery pack and loading another, it also saves time when the time is at a huge premium.

Locally-generated solar electric power to charge the batteries is also easier in a farm environment, and makes direct financial sense.

The same dismounted tractor batteries, when not in heavy use, e.g. during winter, can work as a "power wall" to supplement the solar power during dusk when days are shorter.
