I just bought a new 1045 and there seems to be a metallic sound when at idle. It sounds like it is comming from the engine, Not sure though, Any thoughts?
Take a peek underneath while she's running. Some have had issues with the double pulley for the deck drive flopping/moving. Something about a poorly designed tensioner spring and/or bushing on the unit. Apparenty some dealers are aware & have a fix.
G/luck
