I have never seen a retaining pin break before.Did you find the broken pin or just assume that it broke?Hensley and possibly others used to guarantee their teeth against breakage,if they break they will replace them.I have done a lot of prying over the years but never broke a pin.As you probably know,don't ever run the machine with a bare shank as they are not hardened and will wear quickly and then the teeth won't stay on.Even if you have to put a worn tooth on it temporarily be sure that the shank never gets exposed to the soil.I have used the bucket very carefully to find a lost tooth and felt guilty about it after but when a tooth is missing the machine is down until it has been replaced.Ron G
Nice work there Bud:drinkup
Just found your post, don't look in this thread very often But i'm glad I did.
Looks like you've got everything under control... I see your using a fire pit like I do, seems to work better and just piling it up on the ground. Plus all the ashes and nails are in the hole!
Now i've got to do some updating on my work pictures
