Got home tonite and scraped and changed blades. Go to grease and lift foot plate up to get to the deck idler pulley. Usually grab the belt and squeeze it against each other to make the idler pulley move while I grease (to disperse it better) and when I let go, the idler pulley stays where its at. Belt was still loose. Go to push pulley back tight, and its kinda real stiff! So I remove the deck belt and the idler stays put. That giant spring cant even pull it back without the belt on it!!! Well, took it all apart and had to press the shaft out of the bushing. Bushing and shaft were only slightly worn, but had all kinds of dried grease inside. I wire wheeled the shaft clean and scotch brited it and the inside of the bushing. Greased it all up and reassembled. Ended up replacing the belts (both mule drive and deck belt) 852hrs on the originals! Figured that I had it apart this far, I may as well replace the mule drive belt too. (Extra belts and filters came free when I bought the mower) They weren't in the worst shape, but I had them and they were getting glazed looking and slightly dryrotted in spots. ANYWAYS.... Make sure you guys release belt tension before you grease and check that this idler remains free to move. I've read about how they are prone to this, but never thought it would happen to me!
