Some days things just happen. And yesterday was one of those days. I rolled some hay for a friend because his baler tore up. Well I just let him give me some hay so he wouldnt be out any money. Well I went back yesterday morning to pickup my hay. He said I could just use his tractor to load it so I would have to bring mine back up there. Well I went to load and crossed the creek, got a roll and headed back across the creek. Well I got over on the edge and got down in a ditch. The creek gravel was soft and it just puled me in. So I had to back out and straignten up. Well i crossed and headed toward the truck and noticed one of the front tires was low. Well I got the trailer loaded and came back for another load. We I returned I noticed now that the front and back tires on one side were almost flat. Instantly knew that I had ran over something. Very bad feeling, considering this is a nice 4x4 New Holland TL90A. Turned out I had run over some very small wood stobs down by the creek. Lukily the tires were tubless and I was able to plug them. No a great experince at all. Makes me not want to use others peoples tractors now.
