I recently bought a used John Deere 350 loader. I got it home, changed all the filters, fluids, etc. Got on it to work it a little bit. Within 10 minutes or so, I began to have trouble. Here are the symptoms:1) When pressed against a load, the crawler will not "spin out". The engine smothers a little bit, but mostly it just sits there once the load gets to a certain point. Somewhat like an automatic transmission on a worn out diesel truck that won't pull. 2) The crawler eventually wouldn't move very well. It would just sit there, even not under a load. Wiggling the steering clutches back and forth would eventually make it go. 3) Related to the above problem...or maybe the same problem...I had trouble steering it. Again, wiggling the clutches back and forth would eventually make it go. But, most of the time the trouble seemed to be that there was no power transfer to the tracks. For example, I would be wanting to turn to the right or left, and the machine would just sit there. Wiggling the respective clutch back and forth would eventually make it "catch" and it would go again. 4) In about 10 minutes of operation, it popped out of 1st gear 2 or 3 times and popped out of 3rd gear everytime. (ie it won't run in 3rd gear) If anyone has an idea where to start, I'd sure appreciate it! I can work on it, but being that this is my first crawler, I don't have any experience troubleshooting or working on one. I assume that either the steering clutches are bad or the reverser is bad...or both. The gear popping, I don't know. Anyone with more experience than I have any ideas or suggestions? Thanks! Jerry
