reaons track come off track loader?

A log or stump getting caught in the bottom of the track may do that--were they adjusted up to the specified slack?
Did your recoil spring break and loose all the tension on the track?

Learn the sounds of your tractor.The popping sound is one you will to learn stop for.Much easier to look at the track and then back up and turn to put the track back on than have it come all the way of .Good luck as you learn.
Many reasons for a track to come off.To much slack in the chain,wear in the chain.Driving over rock,logs and berms doesn't help.

Anytime the machine is turning over a depression that does not support the track in the middle, there is the possibility that a snakey track can get left off to the side of the rollers and run off. If the tracks are snakey, try to turn when you have a hump under the middle of the track that is on the inside of the turn. The outside track is being given more tension by the sprocket pulling that side around and is less likely to go astray.

What ever time is lost keeping the tracks on is more than gained by not having to put one back on.

Just my $.02

Jim,
You kinda describe what I think happened. I was backing out of a low spot. I had already decided that if I ever get this track back on I am going to avoid the depressions and watch how I turn. You just confirmed that. Of course it could have been caused by something else, but that was originally my gut feeling.

I had hoped this 955L would tackle this huge 2 acre mess. The former owner had allowed the power company to dump hundreds of loads of tornado debris a few years ago. We bought the place a few months ago thinking we could burn it, but it is now too rotten to burn, it mostly just disintegrates with the exception of the logs.

Thanks,
DP
