Thanks Hoss. I still don't know how to post a link and maybe that's best. If I knew how to do that stuff I'd probably get carried away with it. Do you want to know how much tire pressure to put in a 1967 Model 120 International tractor? I'd post that. In fact, I'd post it even if you didn't want to know or didn't care. I'd let you know how the temperature, ground conditions and load you're hauling will affect pressure. I'll let you know how much pressure to put in the back tires on Tuesday and front tires on Saturday. Yep, the world is a better place because I don't know how to post links.
