advice planning realization bucket rake ripper for excavator

[barracane]

thanks for the valuable suggestion, would you be so kind to make me a design of the changes to be made or a modified hole, I'm sorry if I'm petulant, I also put into account that you could damage the bucket, I had experience with an old backhoe houses who has set up a large boulder of rock incocciato while proceeding to the digging operations, as in the image you rightly attached, thanks again
