Removing blades from USAT rotary snow plow

[jblodgett]

I would like to remove the blades from the shaft on my USAT rotary snow plow. I have removed the acorn nut from the end of the shaft, but am not sure now, if the blades are threaded onto the shaft also, or glued on etc. Has anyone gone down this path?

I will reply to my own post in case it helps someone else. I found that there was no way I could get the blade assembly free of the shaft so I moved my efforts inside. There was a little circlip in a grove on the shaft preventing the shaft from moving outward. I removed that. Then there was a brass flywheel that seemed to be held to the shaft with CA cement. I was able to hold the shaft with vice grip pliers, grab the flywheel with large channel lock pliers and twist it to break the hold of the CA. Then wedging a large screw driver into position I could lever the flywheel off the shaft. That flywheel is now drilled and tapped for a set screw for when I replace it all. I was now able to draw out the hole rotary blade assembly and shaft out of the front of the plow, and am working on a brass replacement for this. After that, the puny motor will get replaced by something with real power.
