I have to say that our local dealer is excellent!! The parts man is polite and knows his stuff. Some of the previous guys in his job were less than enthusiastic.
Thankfully they weren't there long!! This dealership has been running for around 40 years under the same ownership/ management, and Bill runs a tight ship! One thing that does come to mind though is, we have been buying all of our tractors, and all of our new farm machinery from them for as long as he's been open, so they da** well better be happy to see us coming!
I've been on the other end of the equasion as well, I don't know how many times I've had people ask me for a part for a IH, Ford, MF, etc tractor, when I ask what model I get this glazed look, and "UH,,, I'm not sure,,, I think it's from the 50s somewhere."
Make sure you have as much info as possible,, parts numbers are SUPER!! If you don't know the parts #s, have your tractors serial#, and any casting codes form the part that you can find. It makes a huge difference!!
For the most part,, if you try to help the parts man do his job, he'll be helpful to you. (exceptions to every rule!!
