Let me apologize for not having any action shots at the present. The camera got seperated from me at the worst time. The bucket is at my fathers and the family got him a digital camera for Christmas. I will get him to take some pictures for me as his homework project!
He got to use it for about 1.5 hours while I watched and I got in about 10 minutes. We knew the breakout force would be significantly affected because of the long bucket length. The botton plate is exactly 30" long and the teeth added at least 6 inches. Curl alone will rip out a one inch diameter tree and an 1.5" tree depending on soil, species etc. 3" and 4" diameter trees were pushed over by forking them about 4 feet off the ground and then going after the roots. My turn came on the last half of a 10" diameter stump. It took 3 to 4 different directions of attack and a certain amount of digging at the roots.
One of the techniques was to get a good purchase on a root and then dumping the bucket while driving forward. This usually just made the teeth slide backwards in the ground but sometimes it would snap a 2" diameter root as the bucket "rolled over".
What seemed most effective was a combination of roll and dump coupled with forward motion of the tractor. Traction dictated the effectiveness of this. The ground was wet but not necessarily muddy and traction was generally acceptable. We did leave lots of tire holes though.
We haven't got much time on it yet but I am generally pleased. The stump was wrestled right smartly with the FEL before giving up and abandoning it. This is what motivated me to make this bucket. Twenty minutes with this new bucket and the stump was out so it is definately a success.
There was absolutely no indications that anything was undersized. I saw no flexing or anything else out of the ordinary.
The only thing I might change is the overall length which is right at 36" including teeth. Any length left off here definately increases the breakout force and you'll never have enough of this. This length did dig a deep hole for the animal carcass though. I am thinking at least 8" off this but I haven't used it enough to be sure. I am thinking about torching out this 8" or so by cutting the bucket off clean at the backplate and welding it back on less the 8".
We cleared out about two dozen 3/4" dia trees, a dozen 1 to 2" dia trees and a half dozen 3-4" dia trees all in about an hour.
I would be glad to give any dimensions if interested.
