txdon,
Lots of great pics.
If you add teath to the grapple bucket they will be further from the pivot point giving them less break out force than the standard bucket for digging and prying. You are right , the teeth will much improve the gathering and grappling abillities.
I must ask why you did not consider a 4in1? It may not work as well as the grapple for grappling or the HD for loading but it does both well and can be up graded easily for either and does not need to be but on and off all the time.
Yes, I do have one and like it. It does not do everything real well but it does so much, I do not know what I would have done without it. I did modify it a bit and plan on more to improve it's grapple work. It does pick up logs well. I have not found one it was not able to pick up.
I see you have the powerful L853 loader. Lots of clearing in it's future.
I like the add on square tube grapple as well. Looks like it has been getting alot of work. It is always nice to see the ideas and work of others. No need to re-invent every wheel.
Keep the pictures coming.
