That cuts down on the field -> market distance which, in some cases, can decrease petroleum used for transport. (Not in all cases. A full truck of produce can move a long distance on the fuel used by a pickup/van moving a small amount.)

We’ve also got farmers using electric conversion tractors to work their fields. Batteries are adequate to let one work about an acre per charge, which is fine when you’re growing a variety of crops and staggering planting rather than using a mono-crop system.
