We've been using it allot lately and have come up with some mistakes and things I'd do differently.
The first problem was the fine thread, one inch bolts striped out almost right away. I thought fine thread would be stronger then corse thread, but that wasn't the case. I replaced them with corse thread, grade eight inch and a quarter bolts. Those are holding up great!!
The five teeth were catching debri between them and causing all sort of problems. My Dad thought that if I welded on some flat stock on top of the teeth, it would stop the logs and branches from wedging inbetween the teeth. This worked for that problem, but created another issue.
The flat stock made it impossible to get the teeth into a pile of debri to pick anything up. It cought on just about everything.
I cut that off and then removed two of the teeth. The three remaining teeth are the ones with the bolts on them and also the strongest. This works the best.
Don asked earlier about the angle of the tips. I did it like I saw in the picture of the one I was copying in the Northern Tool catalog. I should have done it the oposit eay and created a sort of skid. The points tend to dig into the ground the way I did it. Next time, I'll make them so they slide on the ground.
The 2x4 tubing is bending. It's a combination of things, but mostly because my dad doesn't have a soft touch. He comes from the bigger hammer crowd. If it doesn't work the first time, hit it again even harder. hahaha
When these are totoly destroyed beyond salvage, I'll build another set with the 2x4 tubing on it's edge.
For what it cost to buy the material, it's turned out to be a very handy, usefull attachment. I'd highly recomend it to everyone who has a FEL and needs to move trees, branches or brush.
Thanks,
Eddie
