I have a 3 year old Weedeater 26" tractor. Last season the reverse stopped working...it never really worked well. I have fiddled with belts and cannot get it to engage. The forward gears work fine. Anyone have any experience adjusting the reverse gear on the tractor or know how to do it...step by step or is there a www.youtube.com video available. I have searcher for both no luck and the manual is of no help.
