Ok I have heard different things on this. I have 2 questions. From the factory on a 1944 farmall h did they come with the tooth style throtle or was it the friction type? And what style of seat frame. I have seen a heard of 3 types. The long goose neck type pole that supports the seat and the 2 spring and shock type. One the spring is right under the seat and the other has the longer shock under the seat. I am slowly restoring a 1944 H and a 1949 M. This year I am fixing all the mechanical and leaks then run them for the summer baling hay then make sure nothing else is wrong. Then next winter hopefully put paint on them.
