I have looked at these set-ups (as in pic above) at my JD store. I think they are pretty slick in the way they attach to the current JD 3rd function remotes. I AM SURPRISED NOBODY HAS WRITTEN UP A REVIEW OF THIS SET-UP. It's commonly called a "Fasse Diverter" system.
What makes it nice is that a neophyte can hook it up....and you could easily move it from your "old" tractor to your "new" tractor....etc. The couplers that connect the Fasse diverter to the JD remotes are a novel "eccentric" that allow for variations in width. Pretty darn slick.
At the end of the day.....this Fasse set up would likely cost about $100 to $150 more (than buying at the
Surplus Center)....but you would have ALL the RIGHT stuff...includeing switches, diagrams, wiring harness, PIONEER COUPLERS, and installation instructions. Not a bad value IMO.
(But....I still didn't buy one.
