So looking at the Ruegg 3 point there is a 140 hitch kit that fits the John Deere 140 300 and 317 with closed frame. My question is would that fit a John Deere 314?
I believe Ruegg 3point for the 140 thru 317 runs off a Bar to the Mid rocker-shaft Like the OEM Integral hitch did on those models Not as Fancy as the OEM 3point with separate Hydraulic cylinder But it gets the Job doneThe closed frame tractors from140 through 317, including the EARLY 316 ('78), have the same rear configuration, so to answer your question directly, "Yes, it will fit a 314."
I'd be curious as to how it raises/lowers. I can't see a cylinder in the pic, so maybe it operates from the rockshaft like an integral hitch. If you get it, keep us posted. Bob
