So we purchase a backhoe attachment that is meant to go on 3 point hitch of a tractor with hydraulics. My husband wants to make an adapter plate that will allow him to put it on the quick attach of our Bobcat. My question is will the hydraulic pressure of a Bobcat blow out the lines on an attachment meant for a tractor?

These specs can be found for both the attachment and the output of the Bobcat on the manufactures website. Both depend on model and year. Even if the bobcat puts out too much pressure you should be able to find an after market pressure valve so as to set as needed.
There are very good “MacGyver” forums for this kind of stuff.
IMHO … 3 point and skid steer mounted back hoes are only better than a wood handled shovel. Both lack the frame connection to use the machine weight to dig and pry.
Depends on the size of the tractor and what you need to do with it. The backhoe attachment on my 45hp tractor did just fine digging a 6 foot deep ditch in December, in Michigan, to replace the valve on my well for only about $100 versus the $2k the well company wanted for the same job.
Sometimes the hydraulic fluid in a tractor vs bobcat is different. You could cause issues in both equipment mixing two different fluids. I’d check that before proceeding.
My neighbor who is a professional dirt mover has something like this:

The backhoe attachment is on the 3pt hitch and it’s not a “toy.” These I’m not so sure about:

We recently had some septic line work done and the guy used a machine of this size to dig up our lines. But they are only 12" deep (sometimes less) so it’s not at all “heavy” work. The system was a Kubota IIRC. It worked quite well for the task at hand but I think it would have struggled with much more.
Mixing skidsteer and PTO implements should be approached carefully.

No, on a dedicated backhoe like that, the backhoe is not on a 3 point hitch. It’s often not even designed to be removable. Here is a picture of the back of that machine.

Quite often, 3-PT attached backhoes are supplemented with a sub-frame on the tractor to provide the level of support and stability required for heavier work. Unfortunately many folks don’t put out the money for the subframe and/or the BH seller doesn’t mention it…
(My tiny Kubota TLB had the subframe actually standard and it is where the BH mounts rather than the 3pt)
I can’t help with the skid steer question.
Exactly.
Yes it is a “tractor” but those are designed for and labeled “earth mover”. Construction tractors with or with out a backhoe and or a bucket are not designed nor set up the same as a “farm” tractor. A friend of mine made the costly mistake of buying a bare bones construction tractor for farm use.
The major draw back is the gearing, ground speeds are all wrong for farm use along with a few other things. I told him to call me the next time he sees a “good deal” on the side of the road. He was bummed, sold at a loss not long after. But I found him an excellent late 60s diesel International 409 nicely set up with power steering. Sadly he died suddenly not long after. But he died a happy hobby farm tractor owner, lol. I inherited it. Have it for sale. Sold my big farm and no use for a second tractor.
I have a pretty big and beefy JD. Thought about getting a backhoe attachment for it. But never found that I really needed it. The odd big jobs I rented stuff. Rented a big trencher to run over 1000 feet of water lines. Goes much faster and easier than a tractor mounted backhoe. If I was to do it again I would rent a skid with a trencher mounted. There is a pretty good learning curve to operating a backhoe well, fast and efficiently. In the beginning I made more of a mess than I started with. I also prefer renting a mini excavator, track hoe. Pretty easy to operate even for a beginner, and you can move along a lot faster. Weekend rates are pretty reasonable depending on your area.
ThirdCharm … The answer to your question is buried in posts.
1… you need the max pressure the BH attachment can handle.
2… adjust the Bobcat’s auxiliary hydraulic circuit relief valve to that pressure.
As Gumtree has posted, Renting equipment for a particular job will usually mean the best match since the immediate requirements are known.
Just having a machine available means it will get used for many jobs not even thought of when purchased. That’s been my experience having a construction backhoe AND a farm tractor with FEL. I quickly learned the FEL is not a very good digging tool.
An excavator will dig well, but can’t travel much.
A tracked loader will push more, but can’t dig small holes or travel far
So, I purchased the more versatile machine …
the Tractor/Loader/Backhoe or TLB
