I don't believe there is such a thing as a "hobby farmer". The term is pejorative, flung about by large land owners, urban navel gazers, and commission salesmen wanting to sell you a "real" machine.
There are Farmers, which raise a diverse number of crops and animals to feed themselves and their families, and sell the surplus to defray expenses...
and then there is Agribusiness, where a near-worthless agricultural commodity is produced in ever increasing amounts in an effort to pay the interest on ever increasing debt by corporations that used to be family farmers.
Farming is a happy, healthy, rewarding lifestyle.
Agribusiness is about money, power, credit, chemicals, and checks from government, monsanto, con-agra, and a handful of other international criminal organizations out to control our food from farm gate to dinner plate.
I wish there were MORE beginning Farmers, and the Agra-cultists can take a bath in the chemical soup they spray on the world...after they've been genetically modified with a rusty probe, of course.
I have farmed all my life. I have a team, and 8 tractors, not counting the backhoe and trencher.. My 'bota is by far the smallest on the place, but critical for my garden and orchard. I would be delighted to share what little I know about the subject with anyone interested.
/the above nearly qualifies as a rant, eh
