John deere 915

[Jd5203]

I am looking at a John Deere 915 mower conditioner with impeller conditioning. First off, are these mowers reliable, I have seen quite a lot of problems with the 920's and wondering if the 915 is the same. Also, I am wondering if I can put a hydraulic swing on it like the 920 has. It looks like the same tongue on it, so I am wondering if I can get the bracket and stuff for the 920 and then rig it for the 915. Any help is apreciated.
