Find a bent or damaged auger some where. 8" preferably. Not sure if hydraulics could handle 10" but likely could. Cut off the same length as your auger and make a hydraulic motor plate for the end. Always seems to be a auger somewhere cheap. I have did the auger from home on our old tow between prasco. It was actually real easy as well with a longer auger spout. I never had to even move the auger back then as I could turn into the auger spout hitting the fill holes every time. Those old Prasco's had the tank attached to the cultivator and backing up required no brains. There were so many things that Prasco had in their design back then that impressed me. Stainless steel metering system standard and best lids I have yet to see anyone beat. They had their TBT tank attached with a system to help the cultivator on dips and rises changing the angle of the cultivator keeping seed at a more even depth than any 5710. The set up made the seeding unit real short too. Not a mile long train. I miss some of that Prasco, But not all of it including cleaning it out.
