</font><font color="blue" class="small">( Please excuse me if this is not the place to ask. I would like to get a back hoe put on a used TC40D (see previous messages). Now, what kind of mount? Dealer says 3 ph is fine. Is it? Pros and cons to 3 ph vs sub frame vs frame? )</font>
Your dealer and New Holland seem to disagree. NH does not like to see 3 pt hitch mounted backhoes on their compact tractors. They STRONGLY recommend a subframe.
</font><font color="blue" class="small">( I have been told it can take 20 minutes to remove a BH from a sub frame mount. That would not be a problem. But, given my lack of hands on experience, I need to ask all of you with more knowledge.)</font>
It takes me about 5 or 10 minutes to remove the backhoe from my subframe mount. I use a PTO pump to power it. I'm betting removal would go faster if I was powering it from the tractor hydraulics.
BTW... others have mentioned that their subframe stays attached to the backhoe, and the whole thing comes off of their tractor. That is not the case with mine. I have a Woods 7500 backhoe with their "4 point" hitch" subframe. The backhoe pops on and off the hitch very easily. The subframe stays on the tractor. The subframe does not interfere with any of my 3 pt attatchments. I don't have a belly mower, but I've been told it will not interefere with that either. I do not have to remove my lower 3 pt hitch arms to install the backhoe, but I do need to disconnect the stabilizer bars.
This style of subframe does not lose as much ground clearance as other styles. I bough the backhoe used as a 3 pt hitch model, then had the 4 point subframe installed. Had to unbolt a couple of things from the backhoe and replace them with arts that connect to the four point hitch, but it was a simple operation. THe only ground clearance issue I've run into happened with both the subframe and the 3 pt hitch mounting methods: the backhoe hangs off the rear of the tractor fairly low. If you are not careful, it hits the ground as you drive through a ditch.
Check out the Woods 4 point BH mounts. They're a great system.
