Posthole Digger 3-Point Post Hole Digger Novice Needs Help Quick

[breakfasteer]

Borrowed a friend's old Worksaver post hole digger (9-in. Auger, I think).
Mounted it on my Kubota B7510 (23 Horse),

Just spent an hour trying to get the post hole digger ( to bore a sample hole deeper than 4 inches. The proper pin hole is chewed up and the U angle piece welded onto the lifting arm of the Post Hole Digger, needs to be replaced and welded on. If we move the pin to a higher hole, then tilt the loader blade so that the tractor tips up, it can drill a bit deeper, but not deep enough for the eighteen foundation holes I need to drill, TOMORROW MORNING, for the deck. I don’t know how to fix this. Maybe the thing is too big for the tractor?

ANY QUICK ideas on how to get the auger to dig deeper?

Feel free to write breakfasteer@yahoo.com. . Pacific Time.

Thanks much!

You DO have the valve that controls the speed an implement lowers open all the way, don't you? A PHD doesn't have a lot of weight and this valve needs to be opened for the weight of the PHD to help did the hole.
Is the auger hitting a rock? Sometimes you need to break these up with a digging bar. A 2" stone setting on the surface of the ground with the point centered on it will not allow the bit to dig.

Yes. Wide open.
Thanks so much for your suggestion.

I am having a hard time understanding the problem. I went to the worksaver site and looked at their diggers. If the three point is going all the way down it has to be digging. Have you checked the 3 point to be sure it will lower all of the way. It could also be the digging points are just wore out and the thing does not want to dig. In hard ground I have stand on mine to get it to dig and I have carbide tips on mine. If the the 3 point is going down it should dig all the way to the gear box. Do you have any soft ground like sand ect you could do a test hole in. Just to see if it will go alll the way down.

I used a post hole digger on a B7100 which is smaller than your tractor so tractor size shouldn't be the problem. I am having trouble visualizing the problem you are having I guess, any chance you could take a picture or two and post them? I realize you are probably out trying to make this work now....

Is the linkage binding where the PHD attaches to the tractor? So you are setting the PHD above where you want the hole, starting the pto, starting to lower the phd...and what happens? It won't dig or won't lower?

Once mine hits the dirt ( clay around here ) I have to kind of pump the thing up and down or it will try and screw itself to china....so I cycle the 3ph lift lever up and down to drop it down and let it dig a bit, bring it up to let it fling the dirt out and repeat.

I recently used a PHD with a 12" auger on my JD4100. Could go all the way down to the gearbox at an idle.

No problems.

I think I'm visualizing that he has not got his toplink adjusted to make it where the auger is perpendicular to the ground.. and he is using the loader to tip and correct the angle a bit..

Any else picturing this?

You do not use the top link with a PHD at least not any of the ones I have seen.

 

[Soundguy]

I guess I've used too many old ones. Havn't used any 'new' ones. "new' meaning 70's and up /forums/images/graemlins/grin.gif

Right, no top link on the one I used. And the gearbox can rotate fore and aft, so I'm not sure how the FEL comes into play. Perhaps he has the "arch" set too far forward so the unit is at too steep an angle?
