Didier 46" Mower

Hey guys, I have run across a Didier 46' sickle bar mower. These things were made for lawn mowers years ago, I know because my Uncle had one on a JD 112. It runs off the PTO through a pump into a motor that drives the bar. Mine works just fine, in fact, it will move just by turning the shaft manually. The hoses look rough, but no leaks that I see. I dug this out of an old barn and fluid was still in the tank.

I am thinking about rigging it to my BX, but what do you think this is worth before I do anything to it?
