Balancing a chopper

Fritz Maurer · Aug 9, 2012

Got a I.H. No. 8 chopper. Some of the knife bolts have little weights attached to them. How do you know which direction to move them to attain proper balance? If it"s a purely a trial-and-error situation, I can live with that; just have to make up my mind to spend a couple days on it. It take so loooong for the rotor to wind down, just to make one little adjustment, and sometimes you go the wrong way and it gets worse. I do not have any broken or missing knives. How do they know where to put the weights at the factory? Thanks, Fritz

Strobe lights with a swensor that detects the direction of motion would work. An old (1960-70s) ballancing system used this method. Jim

If it rolls that easy, the heavy side should end up on the bottom. Add weight to the top and turn by hand. Heavy side will move and add weight to the top.
