TSC PTO Post Hole Digger

[Brenttnhmby]

Bought a TSC PTO PHD for my JD1070 last year while it was own sale. I want to use it to set some 4X4 post to fence in my garden. Need to now purchase the augar. What size augar should I purchase 6" or 9"? Someone with experience, please give me some advice.

9 inch unless you know how to bore a perfect hole.

For 4x4 (5" diagonal) a 9" auger works nice. You want to have some extra room to allow for the auger to drift a little during drilling. Then when you set the post you have a couple of inches all around to adjust the post to the straight line.

I would buy them both,, I have a 6",9" and 12".. some of the cedar post I set I wish I had a 16".. but if you are only going to set a few 4" then the 9"...Lou

If you've got heavy soil,back fill those posts with pea stone or crushed rock. they will stay put and stay straight. Should your lay out change, you can easily pull the posts and re use.
If I were buying only one auger, I would invest in a 12". Even with 4x4 posts roots, rocks and buried junk can divert all but the heaviest machines. Most 3PT augers use gravity to pull the cutting edge into the soil so it's right the first time period.
Another tip I've learned over the years is after you've reached your target depth shut off the PTO and pull the auger. Pull your tractor ahead and spin off the soil. This technique seems to provide a cleaner hole at least in heavy conditions.
