Has anyone replaced this? I cannot locate the part on any parts diagrams. My belt wore out and it bent a few of the blades as it jumped the pulley on the right side motor. I'm thinking I can cut the bent portions of the existing blades off and roll on, any reason I shouldn't? I cut about 1.5 flat acres every week or so with this mower. In case I need to replace this fan how do you drop the pump motor? Thank you, Mike
