After 40 years of buying old tractors and doing the stuff the puts them in good shape mechanically I'm finally where I'd like to be with all 12 of them. This week I had to order a $5 part and had to look hard to find enough stuff to justify the shipping. Now the problem is tires. I bought a Super C a few years ago with both back tires not in very good shape but held air. I bought the last one of those this year and have them both on the tractor. My H has both back tires that are weather checked pretty bad but hold fluid and air for now and I think will for a couple of more years. One rear tire on my W30 I don't dare put another pound of air into it. Now I found a tire on my corn picker I don't trust very far although it did get me through my crop. This morning I went to rinse out and park my sprayer and one tire on that held air just long enough to rinse it out and park it. Got one on my baler weather checking pretty bad. Guess I will be fixing tires for a while. The small ones I have some good used tires and will probably just buy inner tubes. The big tires I'm trying to buy one per year until I have them all to spread out the cost. When I get nervous about the cost of tires I just look at the tires on the big guys stuff then I don't feel so bad. LOL
