If your thinking of one like this then Don't!
Matbro swan necks and booms like to crack in normal use as it is with out trying to put forces on them opposite to what they were designed for.

That’s what I was thinking about but perhaps your right

No perhaps about it.

Without being big headed I know I'm right!
Telehandlers are all designed to lift and push. Not force down and pull back.

I'd also bet money on me finding some cracks of some degree already on your matbro boom! Matbros probably the worse booms there are for cracking! There isnt really a matbro model that didnt crack somewhere or in multiple places!

In my opinion alot of the problem was badly designed tilt linkage/ram strokes.
Most matbro models slam the headstock against the stops and continue to force in to them as the ram strokes are wrong. I have had a few altered with spacer in rams or welded extra on to the pistons and skimmed back in lathe to reduce strokes by 2 or 3mm.
Not much but a little on the tilt ram equals alot at the headstock!

All handy stuff to know , tbh it was to fit on a jcb 270 with pin and cone attachments but I can see why the digging action could be problematic.

I agree, matbro cone and pin is designed for what it is. A fork or bucket attachment. It’s weak at that too.,,,get one made to fit on raw machine (it fits with two pins in place of matbro headstock

doesn't really matter what machine it is the principal of forces are all the same and the swan neck or where the neck of the boom joins the box section is always going to be weakest if you use it the wrong way it was designed for. Them digger attachments do only have a very small bucket BUT its a long way out front of the head stock so the forces or the potential forces if you hit some hard going will be high.

Now if you were thinking of a 3 point linkage mounted ditcher piped with its own spool block and a seat, hooked on the headstock and driven off the handlers hydraulics and with its own feet/legs to support it i think that would be fine.
