HELP, I need a replacement for part #437281 SUBASM.WHEEL.FRICTION, for my Weedeater One- 261, but have only found the entire Transaxle assembly for sale for $322. My Mower only cost $650 brand new, so I don't want to put this much into the mower. Everything but the Friction Wheel is just fine. Can anyone give me an idea where to get this part or one that will substitute?
