Hi everyone, new to the forum, Last fall I purchased a 7100D with loader, grader blade, b2551 snow blower, and a heritage RDC54 by woods mower. It also came with a k-420 tiller that he said was basically scrap metal. I looked into the tiller a little more in depth once I got it home. The guy didn’t seem very knowledgeable of tractors and working on them. After looking into it I found the guy kept snapping shear pins, and decided to weld the tiller shaft to the output shaft. That didn’t hold for him, so I started tearing it apart. I found the output shaft had snapped at the first shear pin hole. I’ve searched all over the internet for anything on the k-420 and have come up with the manual and parts list that I already had, and I have decided to start fabricating a new output shaft and the first 8” of the tiller shaft. This is my progress so far.
