You seem to already understand the most likely possible problems. Forks wear and bend so that the gear does not go all the way into position. It will then pop out. Bearings and gears can wear and get loose that allows them to pop out. Get the tractor where you can look at it and drain a little transmission fluid into a clear or white container. If there is a bunch of metal particles in the oil, you may have a serious problem. If not, pull the shifter cover and check the forks. Get the correct shop manuals before playing with it. We have the BX2200 shop manual in our Manuals Section. I also agree with you that hiring a mechanic is usually too expensive, I prefer to learn to do it myself. Good Luck, Rick
