calling all rotary scraper/tumblebug experts!

Does anybody recognize this? What brand is it? I know how it works but I am curious if some parts are bent or not right. The mechanism that puts it in dig or carry, lacks about an inch of catching in the holes. Thought if I saw one I could immediatly see the problem.

That will sure beat an old dirt slip and a team of horses!!
I have an old one in the junk pile that I will post a picture tomorrow. They are simple to operate once you understand how they operate.
Spent many hours on a tractor around the farm moving dirt with one. Handy if you don't have to move the dirt very far.
Here in the Midwest, if you had a welder and a torch you could build a tumblebug. Many came from small weld shops back in the 30's to 50's.
No hydraulics needed.

Here are some photos of old one I have. "It worked when it was parked".

As it sits, it is just past the cutting position. No idea as to manufacturer.

Hi Team,
another of Toby's videos.

Cheers,

Picture #4 is a couple of old slip scrapers. As a kid I had quite a bit of flight time when one of those hit a rock or tree root. Not the best way in the world to meet up with a horse's butt. It was however, softer than meeting the back end of a tractor.

Hi Team,
Tumbling Tommy, Fresno and many other names for the working animal powered pan scraper--a pair of Australian Bullocks at work with one.

Cheers,
Eddie B.

Eddie, I think this is the video you wanted using the "dirt slip" or whatever they called them and the Bullocks at work.
Thanks for posting Toby's video of the real tumblebug in operation. Looks exactly like the old one I have.
