NH L785 skid steer

Found a somewhat local 1989 NH L785 skid. Looks to of had the older style nh bucket attachment that at some point was modified and is now the standard bobcat quick hitch. Has supposedly 3100 original hours on it, does not have aux hydraulics and has a pretty crappy all yellow paint job.

Talked to the older fella who owns it, said he painted it because the original paint was wearing off and just wanted to keep it from rusting. The left front wheel has some very light oil leaking down it(looks to have been sitting in the same spot for weeks) and has the Perkins diesel in it. Glass side windows and rear. No front door or heat/ac

He is asking 5500 and looks to be in decent shape for 27 years old. The aux hydraulics is holding me back bec I just bought a bale grab and could really use the hookups. Anyone have any thoughts on splicing into the current or is there a kit available?

Thanks
-Matt
