Danuser EP615 Auger System with 9" rock carbide bit. This is an HD unit, not the cheaper ones you see all over online or at the auctions.
This unit is literally new, sat under cover for a couple years. I bought it to try and custom bracket it to my old Deere loader. I had a hydraulic problem with my 3-point and couldn't get the flow right to run it correctly.
The 615 goes for about $2,900 new and the rock bit goes for about $1,500 new. This unit has drilled less than two holes and I sold my old tractor.
I'd like to get $3,000 for it.
I also have the quick attach that came with it but I welded a couple of small brackets to it to enable the hookup to my Deere. They can easily be cut off and you can use the quick attach (with cradle) again.
