Thanks for the help. My fan is rigid. It is setup for it to push air from engine compartment through the radiator to hydraulic cooler.
My father told me that the tractor was overheating from the time he got it (about 20 years or more ago). It was overheating with the owners before him too.
I removed a fan shrouding from the donor 175 that we have. that is also where the torque converter was taken from and installed to fix the pushing problem.
