To answer the last few comments:
Thought about doing the chain type, but chain and binder I do not have and cost $$$. This was all scraps. I have $0 in them and about 2-3hrs work.
As to the length and under the heel, again, working with scraps. But as it is now the heel is only a few inches away from the heel of my Kubota bucket. And its not like its an overly powerful loader anyway. And the buckets on my how and dads how are a good bit stronger. I am sure they can handle anything the forks will lift.
