Reminds me of the fender mounted tractor radios that John Deere sold in 
the sixties and seventies
before cabs were popular. To overcome the tractor noise you would need 
to turn that radio up so
loud that it was probably doing more hearing damage than the tractor 
exhaust itself. And yes,
people off in the distance could probably hear the radio as well or 
better than the operator of
the tractor.  I never had one myself.
