well, not sure if his gives you any idea's
But the guy I bought my skid steer from, added this?? to a bucket, ,he used it for moving 55 gallon drums easier, and also as a step, as he had a stroke and was having a hard time getting in and out of machine
it is simply 1/2 rebar, bent like this and welded onto the back of the bucket, which I would think you could also buld to go on the back of a grapple too
its been very nice to have as I too am getting older
and its been extremely durable
I have moved at 75+ tri axle loads of gravel, millings and broken concrete and pavement slabs, , fill dirt, and lots of other stuff, (plowed several winters of snow with it) and have hooked countless chains to it and pulled out stumps, and likes
its held up rock solid, doesn't bend easy or hang up on anything really, SOME Small rocks of chunks of some things MIGHT get stuck behind it and need me to remove, but its seldom a big deal or takes more than a few seconds
and to be honest, I would add this again to any bucket I ever buy again, its been super useful, not to mention making getting in and out of machine a lot safer!
its has like built in traction being ruff edged rebar, so, when wet or even muddy, its still gets me traction when I step on it
and if you can weld, and bend some rebar, its pretty simple to make and add!, and 1/2 inch rebar ain't that costly either, HAHA!
I am sure one could use thicker rebar if they wanted, and had means to bend it and it would be even more durable and still not limit use of bucket much!
