I don't even think there is a name brand attached to it, but we bought the cheaper of two in the yard at Agri-Supply. No slipclutch, just a shear bolt. Check out the videos below...the 5300 ran it fine around 1500-1700 RPM.
First vid is setup and testing it.
Second vid is of my son and I using it to install gates and some fencing.
If you need an inexpensive 3pt auger, this one seems to do the job. Enjoy!
