I have a Leinbach L-7200 3 point post auger that I purchase at a local farm auction but once I used it realized that the shaft was bent and it doesn't do a good job being so out of balance with the bent shaft. It's a 12" auger and I'm looking to replace it but I want to make sure the replacement will fit. its a 2" shaft and 42" long. Any advice or recommendations on a replacement auger? Will any 2 inch replacement auger fit? Thanks for any input!
