I took your advice and changed all of the fluids. The hydraulic fluid looked great, but the engine oil was another story. It was very dirty, and I think I will change it again very soon. I used the tractor for about 6 hours this past weekend, and everything works great on the tractor.
I do have a few things that make me wonder if the hours are acurate. First, the engine oil looked really bad. Second, the front tires are a different brand than the rear. Third, the engine hour meter only logged about 3 hours in the 6 hours or more I ran it this weekend. (The third part seems to scream at me). The tractor shows no real wear points other than sitting outside. The pedals still have paint on them, and the clutch works as well as any brand new tractor. There is no smoke unless you are chugging up a hill in high gear. I still feel like it is a good tractor, and was a good buy, but it would be nice to know how many hours are really on the tractor.
