Yes it is TO35, 1957 model, was cream color when new.
The plows are MF64 double disc plows, must have been made near the end of the MF disc plow run as they have the bend tube main frame, not very many of them around.
I do enjoy using them as I have some garden spots that were old fence rows at one time. The old disc plows will plow right through roots, stumps, whatever and just cut them out or roll over them and keep going.
I guess the invention of trip plows killed the disc plow.
The little Ferguson is about the same size tractor as the 8n, so I enjoy reading about what you guys do with your tractors.
