Wow this is how arguments with my wife start. The subtleties of the English language allow many interpretations of what someone is trying to say, many times it is misunderstood.
Ok, I'm late to this thread, but here's my take on the OPs original post... I had a Kubota 6040 and from day one, the danged tires leaked down. Yes, great tractor and all, but many Kubota owners can attest, this seemed to be a common occurrence. I believe he was jokingly noticing that other brand tractor tires went flat as well... Of course, I could be way off, lol.
