Want to put a backhoe on a Kubota 5030 HSTC cab tractor/FEL. Problem seems to be that all 3ph hoes I have investigated (kubota, rhino, bushhog etc) will not fit on these cab tractors- they apparently mount with the hoe seat too close to the rear of the cab. Is anyone aware of a hoe that will work with these tractors?? Surely someone must make one that mounts a bit further back--perhaps with a bolt on rather than 3ph mount?? Or adapter/extension to the 3ph?? Any ideas would be helpful.

Sorry, I don't expect to see anything for a while and if they do, I don't expect to much of a backhoe. You already have been told why as it would have to be so far to the rear that the leverage would mean a smaller lighter hoe. Maybe at best a 6 or 7 foot with a small pump. Now you could buy an L-48 and they do have nice full enclosure cabs for those that have a removeable back window assembly for when you don't have the hoe on you can just have the flat window put on to work with just the tractor. I didn't check to see if air is available for that cab but that is about all you might loose. ....

I don't know how far back the cab comes. With my Kelly B600 3ph hoe, I think I sit at least a foot behind the pto drive. The hoe won't be on the tractor again till spring, but I suppose I could measure from the back of the seat to the lower link pin mounts if that info would help.
I always thought that an advantage of sub-frame hoes is that the hoe is closer to the tractor, which reduces leverage for load that a hoe puts on the tractor. The operator seat also is closer to the tractor and I'd guess that if a sub-frame hoe won't get the operator inside a cab than a 3ph hoe might be the only alternative.

The trouble exists in the fact that Kubota's generally have short lift arms. YOu may be able to buy after market lift arms that extent the lower links out 6 or 7 inches. Watch warranty issues though. ....

Does the Kelley hoe sit back further than other hoes?? From Toms description, it seems it must, with the Kubota hoe, you are sitting right over the tractor PTO shaft.
Marks suggestion sounds like what I was looking for, anyone have any experience with aftermarket lift arms?? I will look into this. A compact tractor this size ought to be able to be configured for and handle a hoe. ....

Dang! I have to go to an all day first-air course for us volunteer fire fighters today. I might get the hoe measured before I leave but it will be dark when I get back. The clearance probably can be figured from the distance of the link arms past the PTO cover minus the distance from the seat back to the link pin mounts on the hoe. The second is what I'll measure.
The Kelly mount requires mounting a stabilizer plate on the draw-bar. I believe the mount is capable of distributing some load to the draw-bar. However, the distribution of some load from the lift to the draw-bar helps but probably doesn't change the problem. A 3ph hoe can place huge loads on the tractor from top-link compression.
Mark's point is that longer lower-link arms also mean a longer top-link. There is more leverage, which applies greater loads to the tractor and increases the chances of a failure that might not be warranty covered if the tractor is modified. Of course, the use of a 3ph hoe, or any hoe for that matter, also voids some warranties.
If I did it, I'd recognize the risks. I'd probably stick to a smallish hoe that didn't have great breakout force ratings and I might even adjust the hoe's relief valve setting on the low side. In using a 3ph hoe as well as some other implements, it's generally good practice to use the lowest of pin positions in the top-link mount bracket.
