Callen 64 #1 Posted February 21, 2013 Bought this engine on part of a 1075 last weekend. Looks original to the part of tractor that is left. The engine tag says K241AS. Serial # A35217 Spec 46323C I bought this to put on my 1045 but, the spec don't match what is on the model list on here. I can get this number to come up for Wheel Horse on the Kohler Site,though. Is it possible that there was more than one spec used? Share this post Link to post Share on other sites
