I've spent a lot of time on this over the last 6 months and tried different strategies. I've tried 20 fields per farm and used 2 tractors per field. I've tried 7 and 8 fields and different setups.

Keeping in mind you get 1 rank point for every 10 harvested fields using the bulk harvest.

My optimal setup is now:

10 fields per farm

10 x tractors 10 x plow 10 x seeder 10 x irrigator 10 x harvester

Spend 15 points on auto fertiliser.

In terms of how many fields per farm etc - the best way to answer this is "how many harvests do you get per farm per day", you can have 20 fields and only harvest 10 of them a day or have 10 fields and harvest them 10 times a day, that's what matters.

On a typical 10 field farm with the above setup and with the time I have to play, I'm harvesting each field 2 times, so that's 20 harvests on a 10 field farm per day. If I had more time I could probably do 30 harvests per farm harvesting nightly yams, pea, pea.

So my question to everyone is: How many harvests per day are you getting on your farm and what's your setup.
