So like I mentioned in my other post ,my Self-Propelled ,Dura-Force Silver series Mower is running perfect(Engine -wise) ,but it is now a Push mower .The Belt seems fine .When I pull the bar up to engage the self propel mode ,the pully goes back ,and tightens the belt , but the mower does not move. Does anyone know what parts I might need to fix this ,or is it even a job I could tackle myself? I paid $225 for this mower last year ,after my Original 2001 Duraforce got a bent shaft after hitting a hidden stump. I really cannot afford to buy a new mower again. Any help greatly appreciated.
