With a few projects coming up, we picked up a TSC post hole digger with 12" auger this past week. It looks to be a County Line branded Speeco HD unit.
We figure on using it with both the 1025R and the 3038e, but I did the first hookup & trial with the 3038e. My biggest hassle on that first hook up was getting the toplink pin in. (Probably the first time it has been moved in the five years since purchase) I think the square shouldered pin end and the hollow ball on the PHD toplink connection added to the situation while trying to hold things in alignment.
After finishing up with the test dig and dismounting the equipment, I cleaned up the toplink pin so it was shiney smooth and reshaped the pin end to kind of a "semi wadcutter" profile. This was finished up with some "finish line" teflon based chain lube to hopefully keep rust at bay and moving freely for the next hook up. Time will tell.
Probably the first project should be sinking a couple of 4x4 posts and adding a crossbar to make a suspension point for storing the PHD between uses.
