Ariens Deluxe 28 one year old from Home Depot . Have used it maybe 10 times. Suddenly when squeezing the clutch handle gears do not engage at all forward or reverse. Tension on cable seems very loose and when squeezing it does pull about an 1/8 " but no engage. The spring adjustment for tension is not like the manual or instructions at all. Cant seem to adjust tighter. Not sure that thats the issueanyway.
