Backhoe attachment for Yanmar FX24D?

[Leaferfly]

My dealer says never use a 3pt backhoe
tractors can be damaged too easy and the
cost is a lot more that buying brackets to
hook up the backhoe proper!

Backhoes are an extremely handy tool but some care needs to be taken when installing one on your Yanmar tractor. The problem is that the yanmar uses the bellhousing as a structural part of the frame.

The bellhousing is plenty strong for normal tractor and loader work but add a three point backhoe and you can get into trouble. In order to prevent the tractor from breaking in half you need to be sure the three point has a sub-frame installed. A subframe is a structural brace that connects the front axle support to the rear axle housings. It basically takes the load off of the bellhousing and distributes it safely.

That all makes plenty of sense. Not sure why my dealer would say the Yanmar didn't need a subframe, guess he just wanted to make the sale.
But if the weight and leverage of a backhoe attachment could break through the bell housing, wouldn't it also be a concern for breaking the subframe itself? How stout would the subframe need to be, I wonder. What thickness steel would be adequate?

The problem is I don’t know how much personal experience they have and what their risk tolerance is. It’s like some people will drive on a donut spare for only as long as the manufacturer recommendation, while others know that can be flexed quite a bit if done carefully.

I absolutely get that. I actually put 4 space savers on a car and flat-towed it with a tow-bar from Texas to Florida and back, and i never went below 70mph if i didn't have to. I make a hobby out of exploring the caveats to 'conventional wisdom'.

As a mechanic I often read about people concerned about using this or that on their car and it not being able to 'hold up' to whatever use they're intending, and my main response is YOU the operator generally decide how much force goes through ANYTHING. What you buy with stronger components is basically the freedom to be less attentive to what you're doing, a fudge factor that can absorb YOUR mistakes. Now, operating a machine on 'high alert' can be exhausting if you do it for too long and don't enjoy the task in the first place. I have towed 5000lbs with 3000lb sedans, etc but if i towed stuff for a living id be in a big truck just like everybody else. But nobody ever looks at a video of an excavator opening a beer bottle with its bucket and says 'that level of precision looks exhausting'. If you're doing something you like doing, and enjoy pushing your limit or a machine's limit, it's not going to feel like work unless you actually do it as work (8hr day of it etc). I have a turbocharged 4cyl dodge caravan that has been up to 20psi of boost on cast pistons that everyone said will break at 7psi, and the list of things like that goes on and on.

So if it's something you only plan to do on your own time and you enjoy running machines, i think finding a way to skillfully operate within the limits of a machine and do things other people say it won't do is actually rewarding and fun. But you have to own the risk and clean up your own messes! If you can't mechanically or financially bail yourself out of a broken bellhousing or something major like that, i would think twice about taking the risks. But if you can, and you choose to.. more power to you!!
