I don't believe this thread went as far as it did without mention of the Colt-Browning 1895 machine gun. Nicknamed the "potato digger" by the troops because the operating lever would dig into the ground if fired from too low of a position. It was used very successfully during the Spanish-American war.

frequency and the amount of shaking may also be an issue. Hopefully you can find good enough information/photos to determine how much eccentricity to give your shaft, and belt & pulley sizes.

How many feet or metres of row length are you planning on digging?
Depending on above answer, what would be wrong with using a middlebuster (also known as potato plow) to dig the potatoes. Much simpler in design and cheaper.

I believe he said he has or has used a potato plow but really liked the idea of the potato digger.

Klug it still is not clear to me if you have a ride-on tractor or a walkbehind that you want to use. Can you provide a link to the equipment you want to build this for so at least that part is clear?
Thanks.
Thanks.
I think he is lookin for something like this,
Mini Potato Harvester For Walking Tractor - Buy Mini Potato Harvester,Potato Harvester,Harvesting Machine Product on Alibaba.com
Walking Tractor Potato Harvester/peanut Digger/potato Digger - Buy Walking Tractor Potato Harvester,Potato Digger,Peanut Digger Product on Alibaba.com
It this is what is wanted it looks like a fairly straight forward build.
The lifter/sifter chain could be made from 2 strips of rubber belt with flat bar spanning between them. To drive the belt, cleats could be put onto it and use a sprocket set up.
A old snowmobile track could be made into a potato lifter/sifter set up by cutting the track and building a frame for it to mount onto.

I have taken a particular interest in this thread because I understand Klug's problems - they are similar to my own and millions of other peasants around the world. Being a peasant does not mean that one is of low intelligence, nor necessarilly poor, although poverty is often an additional problem. It simply means that it is essential to live within the constraints of the particular country in which the peasant lives. Many of us have a good lifestyle - my own is better than most of the rest of my life. That is not the point. Klug says he wants to make a potato lifter along the lines of the link he gave in Post #19. He does not have any dimensions. Sure, it looks simple enough to construct if there are some measurements available. Trouble is, nobody has come up with any. The man merely asked for help with dimensions, he knows what he wants to make, but without any starting reference point he is working blind and has to make guesses.
We all know how elevators or shakers work, but nobody has offered any suggestions on the size of the the blade or the thickness of the rods of the vibrating follower, whether an elevator or simple rods as in the link at #19. One thing nobody has picked up on either is the fact that a vibrating blade rather than a static drag blade reduces the power requirement by a large amount.
Unfortunately I do not have any dimensions to offer him either, but telling him what you could use in the US is not a lot of help to him. I am not being critical, because I did not realise myself until I lived here how different life can be in supposed western civilisations that do not have the same markets as others. I too had been accustomed to buying up scrapped or well used equipment at auction, private sales or dealers if I needed a particular part. This is not possible in many countries.
If anybody can come up with some measurements then please help the man.
