There is a current thread about ball caps, primarily KUBOTA caps and T shirts, so I didn't want to post this there.
A few years back I needed to replace the hydraulic pump on my Case 730 and a dealer in Neosheda, Ks, was the only place I could find this pump. They rebuilt them there. They invited me into the shop to see what all they did, I purchased the pump, and when I was leaving they GAVE me a baseball cap with their name on the front. I also noticed under their name was their phone number. So I wore the cap a few times and made sure when I was haying I wore it because the phone number was on it and if I broke down and needed something I could call and they'd send it out that day.
This is an open station 1966 tractor with a canopy to keep the sun off. One day while raking hay I was hot so I took the cap off and hung it on the loader controls. After a while I pulled under a large Osage Orange tree for some shade and a drink. I felt for my cap but it wasn't on my head, then I remembered I put ito n the loader control lever. It wasn't there. I actually went up and down some windrows looking, but it was camo and going to be blended in.
I discovered it that winter in a hay ring!
After that I always though is someone is advertising their company their phone number should be on it, but I guess modern technology over rides that need.
