Posthole Digger Land Pride PHD shear bolt

Go to tractor supply and get the g5 bolts. They are cheap there and you can get an assortment for future breakdowns.

I went to 3 stores yesterday: Lowe's, Tractor Supply and a local hardware store. They all had 3/8" grade 5 bolts but no one had 2-3/4". just 2-1/2" and 3". I need to figure out if the 3" bolts will stick out too far and interfere with anything. Or cut them to 2-3/4". I'll also try the tractor dealer tomorrow.

I wound up going to the tractor dealer where I bought the PHD. The parts guy looked it up (using the same manual I used) and then he suggested I just use a 3" grade 5 bolt form their hardware aisle. I bought several and fixed the PHD over the weekend. Thanks for all the help.

There is two shear bots that attach the auger to the drive

The two bolts that attach the auger to the gear box output shaft are NOT used as shearbolts. At least, not on the Leinback PHD's I have used. There is a reason for that.... Just imagine if you have the auger buried deep, and then you sheared BOTH of those bolts, what's going go happen when you lift up the PHD??? The auger is going to stay buried in the hole. This is why there are TWO bolts on the output shaft, and only ONE (shearbolt) on the input shaft (to the gearbox). Hopefully, you won't ever shear the pair of bolts off and not be able to pull the auger out of the hole.

On the Leinbach's, the PTO shaft has a set screw on the end that attaches to the gearbox. The set screws rides in a groove on the input shaft. This is so that when/if the shearbolt does shear, the PTO shaft will hopefully stay hooked up and not come off and start flopping around wildly until you can you disengage the PTO drive.

See post#7, We already covered that.
