There's alot of good used "Ag iron" out there - for pennies on the dollar! Much better in the long run versus tearing up and paying for repairs on your "too small" tractor.
zz and SPYDER and slowzuki have been successful by carefully matching their tractors with smaller, older balers.... and being very capable at repairing and maintaining those older balers!!!
You have to be willing and able to work on those older balers. And you have to be on the lookout for spare parts machines and other sources for reasonably priced parts and repairs.
If that describes your "MO" - keep reading and searching here on TBN. You'll eventually gather a list of baler models and even possible tractors that would fill your needs and match your pocketbook.
