New compact track loaders for mulching

I currently run a Cat 299D with a Fecon mulching head and a brush cutter. I'm done with the Cat due to the tracks coming off all the time. I work alone in allot of swampy areas and I'm tired of bringing in a excavator to pickup machine to put a track back on!
Now I'm looking at a new machine. Anyone have any favorites out there?
I work in allot of low land areas, have my share of rocks also.
