HI, I'm new here. I recently acquired a Kubota L240 before I knew anything about gray tractors. All was well for a while, but now I have steering problems. I am having trouble with finding parts for this tractor. I need a steering shaft. The block is 1 1/2" wide and 1 7/8" long. On line, I can only find a steering block that is 1 ½ X 1 13/16”. Please let me know if you can help me. Also is there an American model the is similar to cross-reference parts? Thanks for any assistance.
