I have a saw that I believe was made by Sears that was made specifically for a Farmall M or H, depending on which way you turn the mounting brackets. There is no ID tag that I have found. I think the 700.141 is a slider table and the 700.140 is a angle table [not sure]. I bought it from a man who said he had used it for 50 years on a Farmall M, I think he was the 2nd owner. The brackets look factory made that are used to mount it to the tractor and not homemade, [Perfectly made], It has a slider feed table, the saw mounts totally on the front of the tractor with no ground support. Does anyone have any manuals/literature on these saws made by Sears? Thanks.
