Hey guys first of all i love this forum and have got advice previously which was very helpful. ANyway we have a 216 which runs great and after the last mow on Saturday I went to disengage the blades and noticed they didn't shut off. I have not changed any belts or done anything, this just came out of nowehere. So basically now when you fire up the mower the blades are engaged at about half speed, then when you flip up the handle to engage them fully they go to full power. It's almost like having a short belt, but I know this is not the case because i haven't changed it and it worked fine all year. Also the drive variable speed belt is in new condition and for some reason the variable speed adjustment is not doing anything. I've heard that this moves on a shaft and might need to be oiled so that it can actually do something. i adjust the variable speed per the manual by loosening bolt and turning motor over without spark.
Any advice on why this belt or pto turn on would cause the issue of making the blades run at all times?
