Very nice setup! I might be a bit biased since its near-twin is parked in my shop. I wish I could give you a list of things to watch for based on my experience with mine, but mine has never down for repairs or needed anything beyond routine maintenance. Oh, I forgot... there was a faulty air cleaner sensor that needed replaced once. But that's it for actual mechanical repairs needed since 2002. So my suggestions boil down to good maintenance. Keep the radiator and air filters clean, lube it regularly, etc. If you can, get a shop manual.
One thing in particular regarding the backhoe, its operation puts considerable lateral and fore-aft loads on the tractor. Be sure to check all of the loader and backhoe mounting bolts for tightness periodically; likewise for wheels, rops mounts, etc. If this is your first BH, take your time learning how to use it. More practice = more skill.
Highly recommend adding a toothbar to that loader. Increases the already considerable digging ability.
Have fun and be safe with that beast. You'll be amazed at the work it can do.
