Is this really that important though? I haven't numbers that indicate that farming machinery is such a big share of the oil consumption. My thoughts on these things is, if we can cut 90% of gasoline/diesel use with BEVs and PHEVs, then the last 10% could feasibly be fueld by renewable hydrocarbons. The development after that is up to the markets.. probably pure BEV will be preferred over time as batteries get better and we develop new solutions. Why would you need three to five packs? A pack can generally charge as fast as it can discharge.. you should only need two if you have a fast charging system. The problem is if the machines is only used part of the year. For the cost of a battery pack to make sense, it should be used as much as possible. If it's idle for large parts of the year and it can't be used for anything else, it'll be hard to justify the cost. Maybe they can double as grid storage?

Farm machinery is not a huge part of agricultural energy use, and agriculture is not a huge contributor overall consumption, but energy's share in food production costs are high.

You also need a third in case one of the first two goes pop, and because batteries don't like being left on the shelf fully charged (or discharged), it needs to be actively cycled through. That's N+1 redundancy; N+2 means four in total assuming you can charge as fast as you can discharge.
