For those of you who have not seen this set-up elsewhere, here are some pics of a 1979 HT23 with a Danuser CD-1 (Compact Digger). This attachment seems to be pretty rare. I have seen a pic of one mounted on a Cub Cadet, and have seen one mounted on a JD at a tractor show in Indiana. That's it.

Danuser is still in business, and does make post hole diggers, but not this one, and not this one for a long time.

The center pic shows the gear box that connects to the tractor PTO driveshaft, just like the tiller would be on a Large Frame.

I bought it separately several years ago. I had originally bid on it on eBay, but lost the auction. Over a year later, it reappeared on eBay, and I won it from the previous winner for less than I had originally bid. He had been trying to fit it to an old style International Cub but found that the PTO drove the wrong way for the digger.

The main unit was complete, but was missing the top mounting bracket and the driveshaft. I fabricated the top mounting bracket to fit the extended frame rails on the HT23

Very cool attachment. It the drill head reminds me of the old milling/drill press machines at the one factory I did work in. There were some antiques in there. Thanks for sharing. :D

these are so cool. i am tryin to make a deal on one for the 1050. he said he will sell it to me because he knows i will restore it an it will be at a good home. we are tryin to come up with a price. what do you think one for a tube frame is worth all complete other then the auger bit is missing. danuser is still in bisuness i beleave so i should be able to get one. if not he said he will get me one no charge

Sam,

The unit itself for a tubeframe, without auger, is probably worth at least $1000. They are that rare.

Danuser does not have replacement augers for these. You would need to find an auger of the appropriate diameter, and weld the right size sleeve on the top to fit the digger head. Glenn Danuser (grandson of the founder) told me that the augers for these were made to fit only these, so folks would not mix them up and put the wrong auger on the CD-1. And the augers are designed to only go down 30", so the augers are shorter than normal, too.

How does the power transmit from the PTO to the auger? I cant seem to envision how the auger head can move up and down and recive power at the same time. Is it chain and sprocket?

It is actually a belt drive, where the sheave on the power head is able to keep constant pressure on a very long belt as the head goes up and down. There is a sheave at the bottom of the unit that is driven by the PTO and there is another adjustable sheave at the top to complete the loop. In really tough soil, I would expect it to slip, but I have never done that so I don't know for sure.

I think a chain would have been better myself, along with idlers positioned to wrap more chain around the digger head driven sprocket. But they didn't ask me. :-)
