Hello all, first off, please let me apologize for not knowing the exact model right now. I am trying to buy a JD riding mower from an elderly couple. I went to go look at it and it starts fine, mows fine, moves fine. I believe it was 19HP? It has the type of transmission that the further you push the right pedal, the faster it goes? Forgive my ignorance, but I thing that is hydrostatic??? Anyways, my concern is, that when I let off the brake, it makes a sound, kind of like the blades are spinning, but not as loud. I crawled underneath it and it looks like there is a fan blade on top of the tranny. Is that what is making the noise or is there a problem that I need to be concerned with?
Im sorry my question is so vague, but anything you can tell me to check would make me feel better about my decision.
