More Post Hole Dig Advice

[Alex_Mendoza]

Hello Gentlemen:
Once again I thank you in advance for your input, I got a Deere 4115 with a Land Pride 15 series PHD with a 12 inch auger (puting some plastic 3 rail fence 5x5 posts) the auger works great as long as the groung is fairly soft, I came upon some hard dirt and was able to go about 8 inches or so before I had trouble, I stopped and filled the hole with water and tried again the following morning with fairly good results.
Would using a 6 inch auger to do an initial hole (pilot hole) and then using the 12 inch auger make the job any faster? any other ideas?
Thanks again for your input.

Alex

It is my understanding that the bit is what does the biting and the flighting just removes the dirt. Drilling a pilot hole with a smaller auger wouldn't gain you anything that I'm aware of and might not even work.

A smaller auger should penetrate easier, if you can live with the smaller hole.

My two cents, anyway.

Perhaps some of the more experienced diggers will chime in, but I'd think this could cause a problem since the 12 inch auger point would have nothing to dig into.

I actually did a bit of this for a totally different reason. I was planting trees. I had a 9" auger on the tractor, my neighbor had my 12" auger in his locked garage and he was out of town. I drilled the holes with the 9" bit. A week later I went back to some of the holes that Ihad previously dug, but had not planted, this time with the 12" auger bit. The 12" auger did dig into the holes, but it sort of wobbled and I had a harder time making a straight hole. As I was planting trees, I was not really concerned about perfectly straight holes anyway, but it was a bit harder to do. But it did dig right in.

Well.....sounds like I will be stuck putting water in the initial hole and just wait....then go at it again.....
Thanks for your advice gentlemen.

i have found, if you will take a 15-20ft section of pipe, and secure it along the top of the arm that holds the phd, so it sticks way way way out past and away from the digger, you can put some weight on the end of that pole and the digger will dig much much better...

heehaw,
I have saw the extended pole method used on diggers, but I bought me some cast weight to use on my digger. I need to weld a bracket on for the weights. I don't use my digger very often, because I have a Danuser post driver that I use mostly.

i think, and it sure hurts when i do..but the further out from the digger you can put the weight, the better it works, so less weight is needed..just stay way clear of the drive shaft and the auger.

Not to change the subject to much. But are auger connections to the gear box generally universal. In other words do you need to get augers from the manufacture of your PHD to fit.?

No. I've seen augers that use one bolt to attach to the output shaft, two bolts at right angles, round shafts, and hex shafts.

No. I have a Leinbach PHD and bought an auger at Tractor Supply. I just had to measure the output shaft as well as the location of the mounting bolts.
