If you would have bought an Allis-Chalmers Roto-Baler back in the day, you would need something to understand how the machine worked. The buyer would have received his operator’s manual, but I am not sure of the circumstances a buyer would have received this small booklet. This booklet has some information about the Roto-Baler setup and a troubleshoot section. I happen to have one, so I thought it would be helpful for some current Roto-Baler owners to have this information to set up their machine. Maybe, if there is interest, I will upload a full copy of a Roto-Baler manual and parts diagram (Click the picture to view the booklet).

I have come across all too many accidents in my research involving these, the book was not as popular or well read as it should have been.
It would be great if you could upload the entire manual. I just purchased one and want to learn as much as possible.
Thank you
I am considering uploading the manual in the future.
