High to all. Although, not a true tractor owner I recently acquired a troy bilt horse and am in need of some parts and advice. Looking at this site I saw several post about the horse and many good replies so here I am. The tiller has a Kohler magnum 8 engine but is missing the air filter cover and I am looking for a replacement. Kohler does make them any more and I'm having a difficult time locating a replacement. Finally, I want to print an owners manual but unsure which year or version to print. The SN is 00942235, making it a 90's (I think) vintage is there any other particulars to look fore before printing the manual. Any advice on the manual or filter cover is appreciated.
