Does anyone know how the band cord #175 below is used to secure the PTO Stopper #170? I can't figure out what it is intended to hook around besides the stopper. It may be intended as an anti-rattle device as the PTO has several mm of twist. This rattles when blades are engaged. I have replaced spindle bearings and verified idler bearings are good. It appears band cord #175 is just a zip tie.
