JD650 Seat Replacement - adjustable swivel

[sporteus]

So, I have a dream that I'll actually be comfortable on my little compact tractor. The seat is about 2 inches too far forward for a 6' (non-compact) person and I'd like to mount one on a swivel so I could use it for the backhoe too The backhoe has a separate seat mounted to the backhoe frame that is falling off and way too close to the controls (looks like I'm playing with myself when operating it) for comfort.

So, I have in my mind that its on some sort of adjustable swivel mount. Anyone out there do any mods like this? I would love some pictures to give me some thoughts.
