Sorry, not to get your hopes up, but I have no help for you. But I'm interested to see the responses. I have purchased a new Wallenstein GX600 bh for my new NH TC26DA and it's a 3ph mount. (my choice, based on my desire for ground clearance on my rocky terrain versus the frame mount). I have yet to take delivery (next weekend). I asked what people thought about what I could pull from a 3ph mount and I only got 1 response...which was not very helpful ("your tractor will break in half"). I assume that 3ph mounts actually work, and I see that you are going the same way...so I'd like to see what others think. I'm paying attention, but otherwise I'm afraid I can't give direct help...

This may help you with dimensions. THREE POINT DIMENSIONS
It's shown where you use your top link, but most backhoes have a rigid steel bracket coming from the back (bolted to the hoe) that hooks up to your tractor, eliminating your top link for backhoe use. Mount the lower lift pins as shown for your tractor category size.
As far as the subframe, I used my backhoe for all kinds of heavy duty work without a subframe. Ultimately I gave in and made one for it just to ease my mind. However, a 3pt mount backhoe should work fine if your tractor is beefy enough to handle it, even though a subframe is definitely a sturdier attachment. Attached is a sketch of the brackets on my hoe.
Hope that helps a bit.

Briancd,

I bought an old Ford TLB with a full 6"x2"x3/8" C channel frame to mount the hoe and loader. The rear end and transmission housings were both cracked from the stress of using the hoe. Both had been repaired, cracked again and the cracks were on the march to split the tractor at new and interesting places. Both had to be replaced. $$

I've also pushed down with the hoe while digging into hard ground or when finding a hidden rock and had the rear of the tractor come off the ground. My imagination says that a 3pt mount where the lower arms don't resist upward motion would be more "exciting" in those situations.

I would never buy a 3pt mounted hoe after seeing the damaged caused even with the use with a full frame. Of course, a small hoe used by a responsible adult in soft soil at a slow rate would probably not result in damage. Still, some (most? all?) tractor companies won't warrantee a tractor if it has a 3pt hoe. Frame mount only. Makes you wonder why...

That was a very good response. There have been many compact tractors that have used the three-point attachment and not had any problem. BUT, there has been many that have broken their tractor in half. There are pictures here that show what can happen. You would need to do a search to find them. Compact tractors were not designed to take that kind of abuse on their TPH. That is why the tractor manufactures sell sub-frames. There are even tractor manufactures that won't warranty any breakage if a TP hoe is used.

New Holland and Kubota to name 2. I think you'll find this to be true for most manufacturs.

Well now that I'm taking all of this in to consideration. I live in Sussex Co. Delaware sandy soil. But I believe I will go with a frame mount. I thank you all for your opinion Drew

Interesting pix, John. What model Ford tractor is that? It looks
like a farm tractor (8N? Jubilee?) and not a Ford industrial tractor.

As for subframes, I always go with them. It is interesting that Kubota
is now selling a 3-pt mount backhoe to go with their tractors. I asked
the factory rep at the recent World AG Expo about their 3-pt disclaimer
for backhoes and he said the warranty on the tractor is not voided
only if you use their 3-pt hoe on a Kubota. The warranty on the
tractors is voided if you use a non-Kubota 3-pt hoe. He knew it made
no sense.

I've got ARP875 and modified it for subframe that slides into my loader frame rails. It was CAT2 captive type lower (don't look for pins, but 2 plates with holes) and OEM toplinl is 2.5" square stock. I would think the OEM mount is still there.

dfkrug,

It is a 1963 Ford 4140 Heavy Duty Industrial Tractor built in July with a 4 speed with Sherman combination transmission, the 712 Super Duty Loader and 14' 723 backhoe. I have completely rebuilt the tractor (eng, trans (twice), rear end, front end, frame, steering column, cylinder, pump and hoses -- among other things). Here is a slightly better picture of the whole thing.

I only did the parts that are blue and bright yellow. Just starting on the hoe. New pins and bushings, crack repair, cylinder rebuilds etc.

Some people call it a bass boat, due to my choice of seats. Ahem, they are comfy, swivel and can be quickly removed. You can see the characteristic cast iron nose and frame rails that delineate it as a HD Industrial.

And back on topic, even with the full front to back frame out of 3/8" steel, it still nearly cracked in half. A 3pt mount hoe is only good for very light and infrequent duty, but that's just my opinion!
