My dad, in partnership with his brother, mainly owned a dairy farm in NE Minnesota where the primary industry is iron mining. In the 1930s and 1940s there were thousands of people working in the mines, and each miner had a family. My dad picked up an International Harvester dealership and flooded the area with Farmalls. Small farmers, flat area with poor clay soil (in the late 1800s and early 1900s logging was king) but there was demand for fresh milk. Our main competitors were Allis-Chalmers and Ford with very few John Deeres. Now that I've required from my engineering career and moved back to my home area for retirmeent, most of those farms have been abandoned - there are only 2 dairy farmers within 90 miles. One neighbor, also returned from the big times as an OTR trucker, has his father's farm including 4 Fords. My nephew, one of the two remaining dairy farmers, is still using an M and an H my dad sold for things like pulling hay wagons around the farm. But when you were using horses for farming, a Ford 8N was a big step up. I remember having 3 widowed neighbors trying to maintain the family farm - husband KBH - killed by being kicked in the head by a horse. Although rear rollovers with Fords and flipping their tricycle IH's sideways were too common, still safer than horses.
