Why is AutoFarm so common on vegetable farms everywhere in North America, yet has a relatively small market share in the Midwest.  I often notice that pictures of large veggie growers in CA and FL, potato growers in the PNW, etc. use AutoFarm on their equipment.  And even around here, AutoFarm has a relatively small market share compared to Deere, Trimble/CNH, etc, but when it comes to vegetable farms (there's a lot of big ones around here), AutoFarm owns the market, I would say their market share is ~60-70%.  Why is that??
