Backhoe Mount

[shutt40]

Here is a drawing of my proposed backhoe mount.
The Black part mounts to the tractor and ties into the loader subframe and the axle brackets of my MF1529 (details TBD). The red portion stays on my LITW 7601 backhoe and connects to the backhoe 3pt mounting connections.
Any comments or suggestions for improvement are welcome.
Thanks, Frank

At the bottom of the tractor side, make a guide to allow for miss-alignment of the hoe to tractor when putting it back on. You want to get close, but not have to be perfect.

Okay, The tractor side only needs to have one pin on top and one on the bottom. Overkill to have three points on each side.
Now the pin on the bottom hooks on downward. Basically you have the backhoe mount hanging on the lower pin. But rethink this.....Once outriggers are down, the back of the tractor is lifted, so you want this setup to be the opposite way.
You would want the bottom pin to hook upward as the outriggers lift the tractor.

I built this A-frame to mount my backhoe to the 3-point hitch of my JD 4200.

That was why I went with 3 pins the bottom pin was just for alignment, to tilt it up into position. I have since looked at many other examples and decided to go with 2 and have the bottom pin hook upward as you said.
Here are some pics of what I have so far, no pins or cross bracing yet.
I'm planning to put brackets on the back and top of the axle at ROPS bolt locations as well as a cross brace just above the PTO shaft attached to the 2 upper bolt holes you can see in the one pic. Keep in mind it is only tack welded. As it is now it is bolted to the loader frame brace under the axle, I'm not sure if this will be good enough or if I should weld it to the loader frame brace as well. What do you think

Nice a-frame, but are you not worried about having all that weight on your 3pt top mount? Many people have bad things to say about 3pt backhoes, although I have yet to find an actual example of them breaking a tractor. I did find one guy on the net that broke his top mount

Hi Frank!
No I'm not worried at all. I do not have an actual weight of my little backhoe, but I would guess well under a 1,000-pounds. Friend of mine is a mechanic at the local John Deere dealership; this is the way he recommended I build the backhoe mount. I remember clearly him saying you could pick the whole tractor up with that top mount.

Things are looking good.
I made a similar design. This is how I did it, if this helps you out at all???

I had a woods backhoe and I went to the woods web site and down loaded a subframe manual.
From this I made a cardboard template, played with it and made the pieces out of metal.
The subframe is supported by my Rops attachment point by the same bracket woods makes. Then just for extra security I use my 3 point top link for helping out. Woods doesn't use it, but I figured it could hurt and it might add a little support.
Let me know if this helps.

Thanks for the idea, Knight... I was watching this thread to see how it comes out but making a sub-frame out of wood first (instead of cardboard) would work very well for me. Why I didn't think of that, is beyond me...

Thanks Bill
I'll post updates as I go. Things have progressed a little slowly of late, it's cold here, -20 C, and I don't have heat in my garage. Oh well I have until spring to finish so no rush. You have to like the woods site, no shortage of free info there. Too bad more companies weren't willing to share manuals like that. If they have that much support on the website it makes you feel confident about the support you would receive if you purchased their products.
You wouldn't happen to have any pictures of your mount?
Thanks again for the advise and support.
