So my dad has only had two Wheel Horse tractors since 1968. His latest one is a 312-8 that I believe was built in 1985. Mowed with it yesterday. Very similar to yours JC. I have a newer 315-8 Classic that was built in 2005 that is very like new. It only has like 250 hours on it. My dad's had to be one of the last before TORO bought Wheel Horse as it was still built in South Bend Indiana. I think my newer one was built in Minnesota.
