At this time, my Grandfather was farming with horses in the upper Midwest.
However, there were cooperatives that could be joined to get better prices on Seed, and all the rest.
2nd, There were Steam Traction engines around( gas tractors just recently being introduced) had by wealthier Farmers who had the cast to purchase one of those Iron Monsters
that could pull a 14 bottom plow, where a horse team could pull but a single bottom plow
So to the advantage of both, he would offer to plow his neighbors fields, for a percentage of the crop at harvest.
That way, more land could be plowed, at a far faster rate, getting your crops planted sooner.
More growing time, better yields. More crop acres, bigger harvests
Same for harvesttime. Combines rather than hand harvesting. Faster, one Farmer could effectively work far more land without killing himself and his sons from the extra work.
In a few years, IC Tractors were a fraction the price of the Steamers, so more individuals could finance tractors on their own. More machinery replaces horses, so lessens the need for set aside acre for fodder to feed the horses, so that land could be used for sellable crops
Production raised the amout, and as economics go, too much supply, prices drop
So the '20s wasn't a great time to be a farmer.
But he owned his own land, even if in debt.
