Has any one had any luck with a horse drawn ground driven potato digger. This is a Hoover digger that I set up on my 630 Case draw bar and used the depth handle on the digger to lower the shovel head. Out of four rows of spuds only one row was successful the rest plugged the digger. When this machine works properly it dose a great job. I’m thinking about converting the machine to a three point hitch so I can lower the Shovel head with a little more control. The digger was not complete when I bought it there was originally a set of iron wheels in the front and I think they helped control the depth of the shovel. That Is one of the problems that I have the shovel wants to go to dept into the ground and plugs the machine. The other thought I had was to motorize the chain This way I could stop the tractor and let the dirt clear out.
