So I have known that I have a slow leak on one of my 841 Ford rear tires. Been trying to waiting till I catch up with other things to fix it. So the other day a guy calls wanting a bale of hay and that is the loader I have to use to load the big bales. Go to air it up and get it aired up and pull the chuck off and I hear this hiss. Touch the valve stem and it just pops off the tube. So now I have a guy coming to get hay and the tractor has a rear flat. Go out and look at it when the guy gets here and it look good enough to load a bale but when I start it and the 3 point goes up with the blade on it it goes way down. Figure what the heck It pick up the bale and back out of the hay barn and then have him drive under the bale. Got it loaded up and have the fluid draining right now. I do not plan to put fluid back in if I can help it.
