I have a 1967, 607 Wheel horse tractor with a three speed transmission. It will not stay in third gear on it's own. If I am holding it in the third gear, it will stay. If I am pulling something, it will not stay in place. I have a 1968 Commando 8 that is pretty much identical. I am in need of a repair manual, and, or advice. I am not able to get on here very often. If someone could point me to a place on here that would be great! I also remember someone selling decal kits for the Wheel Horses. Is that person still selling the decal kits? Thank you very much in advance!!!
