Ditto Australia.
This is "normal" - clearing, ploughing, seeding are short intensive bursts, harvesting the same.
Much of the rest of the year it's maintaining equipment, fences, and twidding thumbs, except that's boring and unproductive and so there are "filler jobs" - running a small business (welding, rousting, wall building, landscaping), renting properties, etc.
It goes wider than farming; for decades most rural areas I've lived and worked in have had most of the locals having several overlapping jobs each - too few people, much to do, no one task takes up full time, etc.
I stayed with a succession of farmers while cycling across South Africa (with all the land fenced off, your only choice at the end of the day is finding a driveway and following it up to the farmhouse in order to ask for lodging), and what really impressed me was how much reading every one of these farmers was doing. Soil science and so forth is apparently a continually evolving field, and a modern farmer has no choice but to keep up with it. It really challenged my citybred prejudice of farmers as somehow uneducated.
But I got your point.
