Post hole digger for FEL

Sounds great. I will say I wish I had waited for cutting until the motor showed up. We got diagrams but they were not the correct ones and we had to recut the entire piece.

I have found another hydraulic motor with a lower rpm and higher torque. It's a Char Lynn with a two bolt flange face, it was leaking bad around the pressure seal so I bought a seal kit and put in it. Can I use this motor and direct couple it to the auger or will I take the small thrust bearing out of it in no time with the up & down forces that would be put on it? I'm guessing it was not made for a lot of vertical forces.

Tough answer as I am no hydraulic expert. Do you have the model number? I specifically got a wheel motor. Figured it had enough beefiness.

Actually, if the motor is cheap, why not use it and see what happens? In the end for me I don't use my PHD more than 10 times a year.

Went for it, finally made some time for this project. Just welded the rest of it up tonight and slapped her on the tractor for a test run.

5:With auger attached

7:A couple of holes later

Looks really nice! Good job!

Looks real simular to my build.

Only I used a truck yoke and u-joint off a drive shaft for my pivot point.

Steve, I'm considering building one myself.
What model is your Char Lynn?
Is the output shaft 2" dia. or did you have to sleeve it?
What is your GPM flow rate?
Thanks

Here you go guys, I built my hydraulic auger last year. Here is what I came up with, quite proud of it actually.

This is using a 12 inch auger direct drive wheel motor powered from the loader power beyond through single spool valve. I mounted it on one pallet fork with a chain holding it in place. The chain in this picture was too small and broke right away. I replaced the light chain with a log chain and quick link attach and no problems since then.

I have stood the tractor up on the bit (front wheels off the ground) on top of rocks/hard dirt, pulled the back wheels off the ground when trying to pull up roots and rocks, and so far,,,, no damage. Sure glad it has a reverse!! Notice the stump right beside this hole. This thing has cut through some pretty heavy roots. :thumbsup:

Thumbs. Ans we have more or less the same design, could you get a close up of the attachment plate Thant goes to the wheel hub. Mine was just a pipe welded on. Clearly you did something better.

 

[Thumbs Up Farm]

If you click on the picture you can also zoom it up to get a closer look at the hub. I used a short 2" solid steel rod with gussets welded to a 1/2 plate for the hub attachment. You just have to be sure there is no run-out when it is put together so there is no wobble to the bit when it is turning. Your attachment to the hub looks like it should work fine. Mine may be a little overkill

The attachment to the fork is what I consider the best feature of this design. Being able to put the auger on and off easily by myself and,, being able to store it when not in use was a big consideration in my design. I can slide the rectangular tube off the tractor fork and onto a channel iron bracket mounted to a post/tree without lifting anything by hand to change it out.:thumbsup:

 

[woodlandfarms]

OK. Here is the killer question for everyone who has one of these.

How do you store it? I am trying to fab up some sort of stand for it and failing at every turn.
