Took these at a dealer by me. The name of the equipment is Hoelscher.
http://hoelscherinc.com This equipment pulls of the 3 pt. and some have hydralics also. There was a scraper model on E-bay that was a demo and had a buy-it-now price of $3000! It said retail was $7000.
That stuff is way above my grade level (no pun intended). In the tight areas I work, pulling those implements around in a circle would be awfully tough. Trees would get in the way and transportation to my jobsites would be a nasty task too. I think I'll stick with my FEL, box blade, rake and tiller!
I currently lack a good rolling capability... even to rent.
Fortunately, no great demand so far.
Solid looking equipment, but better suited to golf courses, playgrounds and commercial development I would think.
