What tractor? Do you have a 'head" and a particular deck now?
I see in jdparts that the blower (powerflow) for the 54C is the same as for the 54D, and would suspect the same is for the 62C and the 62D. Just that the one for 54 doesn't fit the 62 size.
The guy behind the counter could find it, but it would take a lot of digging...and this time of year they don't have much 'spare' time.
