Edulzug

Does anyone know what "Edulzug" means? It is stamped on some WWI German propellers, and several of us have not been able to figure out what it means.

I'm not sure about "Edulzug" as a whole, but I'm familiar with "Zug" meaning "train." Perhaps, "Edul-" has something to do with "edel" meaning "nobly"? I am not sure; my German is very rusty. I would consult a German dictionary and look for aviation related definitions. Good luck.

Hey Dave,

I have the same here on an Axial and a Walther, but as two words.

EDUL ZUG

Dave Watts is supporting the observation that it is all over the place, whatever it means. Apparently the "zug" means something to the effect of "pull" and might refer somehow to a tractor vs a pusher prop, but that's a wild guess at best. Maybe someone will know.

Dave:
No proof, but I think it refers to a tractor propellor. I better add as oppsed to pusher prop. I just knew someone would log on ad ask ," Which tractors have propellers?"

Hi all,

For sure the two props I have are tractor props, (not John Deere nor Massey Ferguson), and are marked "MERC 160 PS", so they are for a D.III type motor.

Best,

And yet, of hundreds of British, French and US made propellers I've seen, I don't think I've ever seen any mention of "tractor" or "pusher" stamped on the prop itself. Why would just German propellers be labeled as such?
The only clue that I know of, as to the type of prop, is that when the decals are on the flat edge, it's probably a pusher, and when they are on the curved edge, it's probably a tractor. Lots of people incorrectly infer tractor or pusher from the direction of rotation, but that's not accurate, because of the variation in engine design, geared engines, etc. A propeller is designed to do exactly the same thing whether it pushes or pulls.

Have no explanation until now but it sounds like a brand name (in form of an abbreviation) of a German propeller manufacturer. I would like to see a photograph of the piece.
