Backhoe backhoe auger hydraulics

[Anonymous Poster]

Anybody care to address probable hydraulic connection/control for a backhoe-mount hyd. auger?
(Roger, have you mounted yours yet, or have it all planned-out?)

I talked to a McMillen dealer, and he seemed a little vague about specifics... I got the impression he hadn't mounted an X450 on a backhoe before.

From comments here on the list, and a dash of common-sense, the logical thing (to me ) is to use the backhoe-bucket scoop/dump action-lever to give fwd./rev. on the auger. The rotation, boom, and dipperstick functions would stay the same, for positioning the auger.

I'd sure appreciate some suggestions as to how-best to connect things!

Also, how might hyd.top and tilt(right side only) fit into the equation, if installed.

(This would be on a JD4700 with "power-beyond" kit and a JD48 backhoe.)

Thanks in advance,

Larry

Larry,

Really Wierd about the messages...

For the Backhoe operation I put quick connects on the Backhoe Bucket Cylinder hydraulic connections. The power head already has ~10' of hose permanently attached for connection to the Top and Tilt when using it mounted on the Loader Frame. I plan to remove the 10' section and install some quick connects on the auger itself to allow use of shorter hoses on the backhoe mount. I will try to take some more pictures of the setup tomorrow.

Just tryin' to get a bite on my previous post in this thread.

Looks like 50+ viewers, but "no comment".

I'm hoping that, with the holidays behind us, someone might take the time to "opine" a bit

Looks like none of the 50 or so of us know anything about what you're trying to do, Larry./w3tcompact/icons/frown.gif Guess you can be the guinea pig and try it then tell US.

Larry,
Sorry I did not get any pictures over the weekend. I was digging water line trenches and never got around to using the auger. I will take some picture the next time I use the auger, probably this weekend or next...

Roger,
You had responded before I put out my "2nd call".
Don't know why I missed it when I checked the thread.

Anyway, wanted to let you know I did get it, and say thanks.

(Must be my Alzheimer's acting -up...at least I think I had Alzheimer's - can't remember!)

Here is the picture of the Auger Backhoe attachement. Hope this helps.

Here is a picture of the bucket curl cylinder connections. The auger speed is controlled with the bucket curl control valve. I plan to extend the "H" shaped BH mounting bracket to have both bucket pins for the curl cylinder hold the auger power head. Today the bracket will slip to the side if you put too much weight on it. It works well, but could be better.

Roger,

I really appreciate your photos and comments!
I have printed them out, and they will be a big help to me and to the dealers/service people who are helping me put this together..., there doesn't seem to be anyone with much experience with these things around here ( or maybe I just haven't found them yet).

To be sure I understand:
Starting at the bottom of the "H" bracket, towards the auger , then moving up - the bottom pin (which the auger hangs from)seems to have (about 2 " ?) of space on each side of the auger-drive frame, which would permit the frame to "slide" sideways some, unless bushings were placed on both (or one -longer) sides to fill this "gap". What is your thinking about this?

Moving up, we then have the crossbar of the "H" itself.

Up further, and we have the pin connecting to the dipper-stick.

Do I understand that you intend to continue "upwards", lengthening the upper "arms" of the "H", and putting a pin thru the ends, connecting it with this pin to the bucket-curl link that is shown resting (with empty holes) on top of the dipperstick?

I guess I don't understand how this extension will prevent the "slipping to the side" that you mention... but it seems to me the "bushings" on the bottom shaft would!

Another question:
Do You think someone could start the auger bit (lightly) into a desired hole-spot, and then lower the boom so that the auger was making a (45 degree, say) angle with the ground, and then , using the boom/dipperstick controls, "follow" the bit as it drilled an "angled" hole? (I'd like to set some "angled" poles. I imagine very-slowly would be the only way to attempt this, both from a chewing-gum and walking standpoint ( re. the controls) and safety (should the auger break loose from the ground at the start, and have gravity start it swinging as it rotated, or something).

I realize there may be a "wacko" element to this idea...so don't hold back on any negative comments.

I'll just plead ignorance

Speaking-of-which, I just noticed something else I'm curious about... Is there some reason you went back toward the operator with the auger hoses, and then looped them under-and-forward to the auger. Looks like foward along the dipperstick and then over-the-side to the auger would be shorter. Are they less-subject-to-snagging on things when drilling in tight-quarters, maybe?

Thanks again,...keep those photos comin' (sure ARE "worth thousands of words"!)

Roger,

That is a real nice set up. Thanks for the photo's. Just adds something else to the wish list.
