Thank you for the reply. I’m only using it to dig up some bamboo roots and a little landscaping once in a while. So basically light duty stuff. I just like having the attachments on hand when I need them.I'm sure a dealer can get one for you. It could even be a dealer not real close drop shipping it to you. I am also pretty confident that Yanmar does not make their own implements. Is it maybe a Woods? I think their loaders are Woods.
You can also get a 3-point backhoe of the appropriate size. The YT235 is going to have a fairly small backhoe sized to it, so it might not be as useful as you are imagining. If for example, you get one with a 6' reach, you will be constantly be repositioning to dig a 4' deep whatever as their is only 1 point where it will dig 6' deep, and you get no digging done with out curling the bucket.. That was what I found when running a backhoe on a comparable sized machine on a Kubota L2550dt, I think with about a 7' reach from my memory. The reach didn't cut it do get even a small job done without multiple repositions, and then driving the machine around with the hoe hanging off the back is a real pain as well. Over the years, Dad blew out 3 cylinders backing into stuff, like a small hill, that you wouldn't think would be a problem.
Basically, really think about how often you will use it, then consider how many days of compact excavator rental the purchase price would get you.
the subframe suggests you are tied tot he OEM option. 3 point opens up the options. I think it is only the aluminum Kubotas where I would completely write-off the 3-point hoes. In general, if the back end isn't strong enough for a 3 point hoe, I would also wonder about other 3-point accessories.I recommend a backhoe with a subframe (not a 3 point hoe) my opinion.
I have a similar sized tractor (35 HP) and I run an 8 1/2' backhoe on it ( with subframe, 8 1/2' digging depth, 11' reach)
I have always been pleased with the power/performance of my tractor mounted backhoe
