</font><font color="blue" class="small">( Digging fence posts with the little back hoe on a BX-23 would work I guess, but there are problems. It's got to be a lot slower, and the hole would be much bigger requiring much more backfill (TIME AGAIN!!!!). Plus if you plan to fill the holes with concrete the BH hole is going to require much more than the PHD hole ($$$$!!!!)
Just going on what I have seen using the WorkSaver PHD on my BX-23, I would not be afraid of using A PHD on a 1500. I never take my BX off idle when using the PHD. The 1500 should have plenty of power. )</font>

1* the hole would be much bigger requiring much more backfill (TIME AGAIN!!!!).
2*Plus if you plan to fill the holes with concrete the BH hole is going to require much more than the PHD.

1*The pads for the piers had to be 16 to 24 inches square so that wasn't a problem also the piers were 16" Square so very little back fill is required.
2*The pads were 4 to 8 inches thick so again there was no excess concrete required.
A 6 to 9" PHD would not have done the job.
