Jack asked me to see if I could find out through my Bush Hog contacts whether a Kohler was ever put in any of the bush hog models at the factory. My contact said he was not aware of one, but if there was one, he was sure it would have been put in one of the HD models.
It looks like it belongs there!
Scott, remember us looking at that one photo thinking it was a Kohler K because of the starter? Well, the other day I looked at that pic real close....and it's a later model Briggs with ring gear starter.
