I am new to tractors. I managed to till and plant a large garden. Now I need to fence the garden in.

I bought a Danuser Digger F-8 with a high S/N and an asst of 2" Augers and an adapter to use them for 2 9/16" with the Digger on my L185. I want to put up 8' fencing with 10' pipe fence posts.

Now my problem is I can't dig deep enough holes. My first two holes are about 20 - 21" deep and I want 24". Since then, less deep!

I had to fix the Digger first, new u-joints and put lube in the gear box. That was before digging. My first two holes are about 20 - 21" deep and I want 24". I played with the 3-point adjustments and now my holes are shallower. The auger and adapter match the length of the auger that came with my Digger at 41".

I have seen a Modification kit to add 50 pounds of weight to the Digger arm. Is it likely I need more weight to dig, correctly adjust something, or something else? I even bought and read the operator manual and it doesn't seem to address my issue.

You may have purchased too large of a digger for your tractor. The problem begins with the size of your tractor. It is too low to the ground. This gives you a small amount of movement for the 3 point hitch. They do make PH diggers for smaller tractors but they are $$.

I would dig what you can and then breakout the hand PHDs.

Post a picture of how you have it connected to the tractor.

An 8' high fence with 24" deep holes? I hope there's no wind where you live...

Are you running into a rock ledge about 20” down? If so, you’ll have to bust-up that rock to get the augur to pull it up.

I'm a bit confused.

Are you running out of "travel" or is it hitting hard dirt/rocks?

If it's a "travel problem" then, I don't see how adding weight would help.

I would measure the 3pt travel with PHD off, (or possibly look it up); Then compare it to the "actual travel" while digging.

From the side shot picture , it looks like you should be able to bury the PHD,when the lower 3PH arms touch the ground. I'm thinking you've hit a rock ledge

The Auger blades are 24" high. Only about a 6" is within the travel area. A few days ago it was about 20"-21".
I wondered if holding myself in place while digging was messing with the hydraulics. It doesn't appear to be. These pictures are taken with the wheels blocked and no brakes.
I wondered if the sway chains could be too tight. When loosened three turns there was no change. Any looser and they might fall off.
I don't know if using the lower or middle hole in photo three will allow more depth, less depth, or cause other problems.
I will check to see if the hydraulics give more or less travel when the PHD is off compared to on.
I will also see if I can dig deeper with the tractor pointed downhill like now, uphill, or across the hill.

There is a severe T-storm warning here so I might not get much checking done today.

Are the auger teeth sharp? The auger should screw itself into the ground, unless you have a layer of rock. You will need a rock bit for that.

Great call! No. One tooth is now broken off and it doesn't want to dig in regular packed dirt. I did find that before I saw this post when I tried to offset the hole. Still a great call as it would have gotten me on the right path quickly.

Great call! I don't know yet if it is a big rock, a rock ledge, or just a collection of larger than gravel rocks. However, it was probably enough to break off the auger tooth mentioned in the previous post. It also convinced me to offset my hole and discover the broken tooth.

I can take a tooth off a spare auger after this storm rolls through and maybe be back to digging holes tomorrow.
Any suggestions on where to buy more teeth? Are the teeth generic or proprietary? One fits all or brand specific?

I ran into problems myself with my fencing project, try a large rock bar and manual digger with water or larger diameter hole with cement, Bent my teeth pounding it into hardened clay, bent them back with a sledge and supported with a few carefully applied welding beads, do not want to ruin your hardened teeth. Yea, post hole diggers don't work as well as you would hope.

Your original post says you're new, so this is not meant to be a condescending question; But do you know that there is no down pressure from the hydraulics on a 3 pt?

I had no idea that was the case when I got mine.

Yes.

There is a mod kit available to add 50 pounds of weight above the top bar. I was thinking I might want to strap on some weight for the same reason. I just don't want to pop a wheelie with it!

When it comes to this new adventure, I am ignorant and I know it. I am not likely to be insulted for long before I begin to understand.

It also helps to have an "observer" off to the side to direct you as the hole is bored. Depending on how your linkage is set up....as your depth increases you may need to back up/pull forward a bit to keep the auger bit vertical as you bore.
In post #10 it looks like your auger is not vertical as you were going deeper. If not vertical....that will also stop or slow your boring process and possibly bend an auger.

Move the top link (main bar) to the bottom of the three holes.
