I have a Toro GTS5 600 super pro recycler 2 with the blade clutch.
I can't find anywhere on the engine that tell me who makes the engine. It is an OHV. There is a Toro stamp on the engine housing. May have been a sticker aqt one time.
I beleave that is what it is also. I need a gasket for the OHV cover and can't find a serial or other information on the mower to find the part number. I will just go to a supplier with the cover and see what he comes up with.
Thanks Austen for the help
