Danuser Post driver

Gerard,
They don't have to be pointed but may help some in the rocky soil. I have put thousands in and never tapered them.

We didn’t sharpen them per say. There were so many rocks, what we did was just cut the corners off of the bottom. That way the post had a chance to go around or push the rocks to the side. Hope that makes seems. It seemed to work well.

Jerry. I see you have a post hole digger too, and I assume the post driver does a better job in the rocky soil than your phd. What type of post driver do you have?

 

[JerryG]

Dave,
Yes, the Danuser MD6 driver does a better job, so far.
My digger is Bush Hog model 2101 with the bear claw points. It I hit a rock just right (or not so right) it will just sit there and spin. I am going to try to fix part of the problem this summer. I am going to put about 110 lbs of weight just above gear box.

Well if you really want to get around the rocks... Back when I was growing up we did some fencing contracts for the BLM. Alot of the fence line went right through rocks and you had to build the fence on line. We would drill a small hole in the rock and put dynamite in it. If you did it right it blew a hole straight down. Sometimes we would have to do it twice. Not that I'd recommend this but it was effective. /w3tcompact/icons/smile.gif

If you are using large posts I would recommend blunts if you can drive
them in your soil. I bought a load of 5 to 6" 8' posts that are pointed.
The problem is, they are heavy enough that once you turn them up on
the pointed end they dig into the soil just by virute of their weight, and it
becomes a chore to get the bottom aligned underneath the postdriver.

While I'm thinking of it, this is a big consideration when it comes to driving
round posts with the Worksaver/Shaver design, that is a where the post
rests in a square channel in the ram. It takes some practice to get the posts
to go in just right. I was very concerned with appearance and I may be
deflecting off of the copious rocks in my soil. If you are just looking to
get lots of posts in fast, then maybe this doesn't matter so much. I
suspect 3 to 4" posts driver better too, though I haven't tried them yet.

Another thing to keep in mind is that the post will tend to lean towards
the tractor. The Worksaver manual recommends that you cheat a little
bit, and this is good advice. Also, if the post starts leaning left, you move
the top of the ram to the _right_, so that the right edge of the ram channel
moves the post back to the left. I mention this because it's opposite of
what you would do with a hammer. Maybe a good way to state this in
just a few words is: do your least visible post line first!

If I remember right, the Danuser has a round channel to hold the post.
Anyone who has experience with this please let me know how it is for
driving posts straight.
