Hi, forgiaro,

I like your ideas. I have a mid-seventies, three cylinder diesel Kubota tractor with a Kelley backhoe. I recently had a narrow, 150mm wide, bucket made for the backhoe specially for trenching and I had three of the proper hardened teeth fitted, the type which are bolted over a welded male peg so that the hardened cover can be replaced easily. I strongly recommend that you add these, since even though they are hardened, they are well worn after less than 100 hours use in variable soil conditions.
