Is the track on the sprocket, idlers and rollers?
If you are running it in gravel or dirt with small rocks in it, it is rather easy to pop a track off in a turn.
If you watch what you are doing, as long as it is not clear off it is not to bad to put them back on.
If it runs clear off, now you have some work to do.
I re-read your post, my above reply has more to do with clearance between the track side and the machine body.
I am not grasping the large gap above the track part of your post. This is a 279C. The only place there is anything above the track is the loader frame above and behind the driver sprocket down to the rear idler.
If the sprocket or rear idler was climbing out of the rail on the track and the sprocket or idler was running on the side of the rail instead of down in the rail like it should be, that would make a difference on the distance between the track and the loader frame. If that is happening, look at the distance between the inside edge of the track and the machine body.
All clearances should be even on both sides. The track edge should be the same distance from the body all the way around the top of the track on both sides.
Sorry for rambling a bit, I was typing while I was thinking.
Yes that is me in the seat having a little fun and finding out what it was capable of doing.
My answer, a lot.
The only thing that kinda scared me, I had it steeper than that, did a 180 turn and the machine was rock solid stable.
I am a little worried that by the time it starts feeling loose, it might be to late.
After I made that steeper, I could still back down to the bottom, drop the bucket and make a 3" cut going up the hill.
A wheeled machine could not even drive up the hill, let alone load the bucket.
