Posthole Digger Post hole digger pto speed ?

[stephan]

I run mine at idle and haven't broken a pin yet but I do dig tentatively, I've got plenty of time. I had some problems with making the sides vertical, though. I was speaking to a bloke once about hydraulic help with a digger and he reckoned you don't need it. He said that if the auger is working properly it will pull itself down, and he makes diggers for a living.

Biggest rocks about my place are about the size of a tennis ball so they can make the digger jump a little but as someone else said just nibble away at them with a bit of up and down (I won't say in and out).

Couple of things I have learnt. It's good to make a rough map of all underground cables/pipes so you don't hit them (yes I learnt that one the hard way, good thing it was only the power to the house). Keep the tip of the auger clear and free from debris which leads onto removing the patch of turf before you dig. And lastly dig a bit move the tractor to compensate for the arc of the digger then dig a bit more.

I've had real good luck running mine between 1100 and 1400 rpm. Sometimes when I pull it out of the hole I'll run the pto up to 2000 or so to sling the dirt off but mostly that's unnecessary.
