I bought a used Craftman garden tractor it came without the owner manual. I need to change the primary mower belt but I can't find the pulley I need to loose so I can install the belt. Can you tell me how I where to look? The tractor model no. is #917-270670, 16HPOHC with 42" cut. Thanks, Miguel.

It's the pulley that puts and releases tension when you engage or disengage the lower deck belt that has to be loosened...
