I only grow my own hay and sell what I don´t need myself, so no real professional farmer. But I can drive tractors and know all the chores of agricultural work. Becoming a "Pferdewirt", a professional rider, in Germany also includes being taught everything about land management that somehow connects to managing a horse farm...haymaking, for example. Pasture management etc...when to mow if you need specific hay, low on proteins, for example etc.
PS: You don´t have to be a super rich guy to drive one of those monsters. Often, farmers work in cooperatives and buy those machines together. There´s also a possibility to drive those monsters if you are working for a "Lohnunternehmen" , basically hired farm hands. Rented workers sitting on rented huge tractors are quite common in agriculture..at least in Germany.
