Kennyd just wants to sell some bolts along with his hooksHere is my opinion FWIW, for small machines there is absolutely no reason to weld on hooks. These tractors can't even come close to stressing the bolt on hooks, and if you weld them (or have them welded) the nice factory finish on the bucket will have to be ground off beforehand, and there is no rattle can paint (even though the JD brand paint is great stuff) that will be nearly as durable as the factory job-it's some super tough stuff. The paint in the inside of the bucket gets burned off as well from the heat on the top side. Worst case, the hack weldor burns through the thin bucket material (10 gauge or 0.1345") creating a real mess, or creates a huge HAZ (heat affected zone) around the weld so it actually makes the bucket weaker in the hook area.
I can all but guarantee they will not put a reinforcement plate under them, and a lot of dealers aren't even using real weld on hooks, they are cutting up the regular hooks and using those.
