I'm new to 8n's, but want to add a PTO posthole digger to my tools as I have lots of wooden 3-rail fence posts to replace. Posthole diggers here (MD)seem to run from $500 - 1200 (new), but they all seem pretty much the same to me. Any advice about what to buy and how much to spend? Also, should I get a 9 inch or 12 inch auger, the posts are about 4 x 6 inches. Any help appreciated.

I got the WorkSaver PhD from Central Tractor, on sale for $349, 9" Auger, and I put in about seventeen million fence posts this summer which were 5" square (plastic). No problem with the 9" auger. I did find that in our clay soil in upstate NY, some water made a huge difference. I mean, a huge difference. Without water, I could dig about 6 inches deep. Then I added some water to the hole, waited for a beer, I mean, 20 mins or so, and it drilled right down. Plus, I added some weights from a weight bench, approx 80 lbs. When you rig it up on your tractor, make sure the chains on the lift arms do not limit the unit from going all the way down to maximum depth. I had to lengthen the chains on my lift arms a little.

Thanks to Danny, Noff and Chuck for the good advice. Seems that the 9 inch auger is the best bet. Chuck- I'm in north Baltmore County, not close unfortunately.

Pete, I use a post hole digger on my 8N here in Southern Md. I have a 9 inch auger and never have any problems getting it to go into our clay. I have gotten it stuck and like everybody else, a good wrench is necessary-I use a large pipe wrench that I never had a use for before. If you drop the auger slowly it rarely "augers in"-don't just push the lever all the way down-let it dig a little and clear before you drop it again. Also, one day we were marking hole placement with those little flags on wire sticks. We just would line the auger up and start drilling. After 2 it stopped digging unless my buddy hung on it. Stopped and found the wires wrapped around the lead blade. Removed them and it took off digging. After that we removed the markers before digging. Are you anywhere nearby?

Very true. here in Texas with the hard clay, my 9" auger will sit there and spin where as my 6" will drive right down into the dirt. I did corkscrew my 9" one evening using a water hose to "moisten" the soil. It went so far down my front wheels were off the ground. Had to disconnect the PTO and turn the auger out with a lug wrench from my 1 ton pickup. Took quite a few turns to get that thing out. So depending on your soil, and hydraulics, 6 and 9 are great. 12 incher definatly depends on your soil.

Pete,

Northern Tools has a 3 point post hole digger for $359. Augers are additional. I would recommend no larger than a 9" auger unless your soil is soft and your hydraulics are in good shape. Sometimes the augers will auger in and you have to either disconnect the pto and back them out with a BIG tool. The bigger the auger, the more this becomes a problem. I have a 6", 9" and 12" but our soil is fairly soft.

Danny
