My pto handle is difficult for wife to move to engage but why doesn,t it return all the way back or is not necessary. They disengage fine but still need more travel at the deck lever for a less slip engage. Has anyone added some washers/shims behing the cable ferrul on the deck or maybe a shorter belt? I,ve went thru this with the forum before, but need more suggestions so whats next New deck pulleys and new Kevlar belt and no worn deck levers and lubed also? Thank you
