You have some great tractors there. I had a thread on here where I put the snow blower on my 12 and ran new cable for the blower chute. I will grab the link to it and post it. I think there were some pictures of the chute with the cable. It took a little bit of trial and error to get it right but I got it. There should be a piece on the top left of the blower that the cable runs to and it wraps around that pin and each end runs halfway around the chute in opposite directions that way when the handle is attached to the crank it pulls one wire in as it lets the other one out. I attached two pictures that I had, hopefully you can get the idea from them. You have the older style blower which I like better, a couple of the guys have your style blower.
