1968 Toro Professional 70"... I can't figure out how reverse works on it.....best I can tell is it has two pulleys (one from the motor and then the drive pulley)...push the lever forward, the drive pulley moves down and the pulleys tighten a belt and you move forward....pull the lever back and the pulleys touch spinning the drive pulley backwards thus making you go in reverse. But my two pulleys are metal and well metal to metal doesn't work to good. I think one is suppose to have a rubber piece around it. Does anyone have an idea?? Or better yet the part I need?? I've looked through schematics on toro.com and can't really tell. Thank you! Mower can be seen here also attached a few pics: 1968 Toro Professional Reel Mower 70" - YouTube
