I have a TC24DA and the 756C hoe, not sure how close this is to your tractor, but this set-up works great. In looking at the Case site, it looks like mine is the equal to the BHX72 model. Somewhere I heard that Rhino makes the hoes for NH.
Hooking and unhooking takes <5mins, and the power is great for the size. I've dug many trenches for gas, water and downspouts. It's good for digging small stumps and pretty much whatever I've needed it to do. Whatever one you buy, make sure it has a sub-frame!
