ORC with post hole digger?

• order soma

There is not enough enertia in the spinning auger to need an ORC. Take it out! I hope the shaft on the tractor is 1-3/8", otherwise you will need an adapter to get the size correct.

Remember, the pto only turns the auger IN! You CANNOT unscrew a stuck auger with the tractor! I take short "bites" in the hole being careful NOT to lift the auger out of the hole. A turning auger out of the hole is a "Killer!" thrashing around, so watch out!!!

Be safe,

If that's the case you've got a couple of options;
1. Cut the PTO drive shaft (to the posthole digger) a bit shorter.
2. Get a 'sleeve type' 1 1/8 - 1 3/8 adapter (which, I've heard, are not very sturdy).
3. Replace your 1 1/8 PTO shaft with a newer 1 3/8 PTO shaft.

Of course, if you've already upgraded to a 1 3/8 PTO, then no problem... Pull the ORC and go to town...

BTW... If you're anywhere near Magnolia... can I borrow your posthole digger? :-)
