Have a AC 615 backhoe attachment off my HD4 - 14' dig depth - Cesna rotary piston swing motor mounted on top of swing .

Kept thinking I would mount it onto another machine after selling HD4 but has set now for a few years as have the AC 715B TLB - have one cylinder now on my 715 as most parts interchange .

I have never seen such an attachment. I didn't even know that backhoes could take much more than a different bucket on them much less somthing that big.

What does it do?

I use to have a H3 loader/backhoe. It was extremely handy as you could drop or reattach the hoe unit in less than 5 minutes minutes. You pulled a couple of pins and then lifted the hoe 3-4 inches out of the lower hooks using the stabilizers, release the hydraulic quick couplers and drive away. You reversed the procedure to reattach the hoe.

Missing bucket linkages - for the price worth it .
About the same as the hoe i have - quick attach brackets are going to be a problem on a 5 or 6 - and you will need a diverter valve in your feed line to your valve body .
Also that hoe runs on a higher pressure than a 5 or 6 hyd system . If you have a dozer - your pump is about 1/2 capacity needed to have any hoe speed
