Sears Roebuck Tumblebug Scraper ?'s

Always wanted to play around with a Tumblebug scraper, and picked one up locally, for $50.

Kind of perplexed as to how the hitch clevis setup is supposed to work. It has a vertical slot, allowing the hitch to move up/down about 10", and a trip lever to catch it, so that the hitch is in the lowest position.

Played around a few hours with it, and can't get it to cut. The blade doesn't want to contact the ground, it just slides along with the cutting surface an inch or two above the surface. If the pan would rotate forward, against the trip stops, it would cut, but I just can't get it to roll forward on its own.

Any thoughts?
 
a picture or two would be helpful. Are you talking about an old horse drawn one, or one for a 3 point hitch? If a horse drawn one, they require an operator to tip them up to dig.
 
This isn't horse drawn, nor is it 3 point. It hitches to the drawbar, and slides along the ground, theoretically, at least. Then the whole pan rolls to dump when the release is tripped.

What you are referring to is called a slip scoop or dirt slip around here.

I'll try to get some pics up.
 
I have some experience with them and know exactly what you are talking about. If it looks like it will work when it rotates up to the stop maybe grease the bearings on the end so it rolls easy. The Idea is that it cuts (not real hard dirt)until full and then if your hitch has a big spring the it will level up and stop cutting when the weight pulls hard enough. Maybe look for some reason why it would not rotate up to the stop like being wore out on bottom. Does the dump stops work okay??(When you trip it to empty the load)

Get your wife to stand on the cutting edge, looks
straight ahead , she will tell you when it's full
 
I have an old one and it works pretty good. the first set of stops on mine are adjustable to set the cutting depth. I just pull it forward and it will lock onto the first set. then pull the trip and it will go to the second set that holds it in place and dumps it out about 2" thick. Maybe check to see if the one set will adjust.
 
We had a Sears (David Bradley) rollover scoop. You have to
latch the hitch clevis in the top of the slot to get the cutting edge
to angle down to cut. Once it's full, it will tilt back and you can
haul the dirt and either trip it once to dump, or hold the rope so
it rolls and spreads the dirt. You'll get the hang soon. I wish I
still had ours.
 
Karl has it right, BUT The scoop wont scoop oin regular ground. It has to be plowed for it to work as you think it should. Putting a new edge on the edge couldn't hurt either.
