So why is it that the back hoes that you buy don't have a sub frame?
Building a backhoe? Anyone ever done it?

They do. You usually have to buy the subframe separately to fit your specific tractor.
There are 3 pt. backhoes out there, but there are many backhoes that can be either 3 pt. or subframe.

Another idea would be to make it a towable model. Typically they have their own engine and hyd pump, but you could hang the pump on your pto shaft. The towable would free the tractor of the stress even better than the subframe. Very easy to connect and use too. I have thought about a standard 3-point attach model like the low cost TaylorWay unit, converted to towable for 3-point safety.

The italians make trailer farm backhoes:
excavator loaders
AS1070
C. Argenterio & CO. srl - Macchine Agricole - macchine agricole
a lot of them were sold here in the 80's but now you can pick them up cheap.
One of these excavators could load a muck spreader or dumptrailer as fast as a self propelled construction hoe, as long as you didnt have to relocate too often.

ok, if im going to make a towable version i midaswell spend the money and make a excavator type that spins 360 degrese. Anyone know where to get the 360 hydraulic manifold for cheap? perferably out of a mini EX

Don't need it.
Mount all your hydraulics, etc. on the "turret" and mount a ring gear on the base. Then everything spins together and you don't have any hydraulic hoses needing to be rotated. Make telescoping stabilizers with pins rather than hydraulics to eliminate the need for hydraulics on the stabilizers.
My vote is still for a tractor mount backhoe. Mostly because that's what I want to make, and I expect that I'll get more inspired following your thread.

Just be sure to watch heat build up in the hydraulic fluid restricting it this way... A better, but more expensive alternative is a flow divider. If this was in the stabilizer circuit which doesn't cycle often, it is no big deal, but for a swing cylinder that will be actuated constantly, I would be concerned with heat buildup.

Dang that's a good idea. I just might implement that into my backhoe. I could have the manual stabilizers, and still just crawl it around, and when I want to turn it from one side to another. I just lift up and use the swing motor to steer it around.
Now I just need to wait until I get some more money to purchase the hydraulic motor, and extra parts. Then I can have my home made mini excavator with 360 swing.
Thanks for the idea.

If you tow it by tractor, you could still operate the stabilisers with tractor hydraulics. But anyways, how often do you turn 360 degree when there is a tow vehicle up front ? If you put the stabiliser lines in a big loop, you could turn 360 degrees too, but just one revolution
