I was called mud sweat and tractors it is a 4 part series about agriculture and horticulture from 1900 through to today
The other programs are about wheat, beef and horticulture
the first program was about milk production, it is a documentary and it was factual as a lot of the things discussed i can remember my Farther talking about and also i remember the 1980-1993 when i was involved in the farm OK 1980 to 1986 was for pocket money feeding the calves before going to school after that i was on the farm.
It really shows why the farmers did what they did and also the effects after the Milk Marketing Board was broken up ( we stopped farming just before this 1993)
here is a link to the program
