First time user here. Hoping someone can help. I have a Troy Bilt Bronco with a 46" deck. I don't have model # handy but it's about 9 years old. With Engine running and blades disengaged, the blades will engage when I lower the deck from the top position to the # 3 or 4 position. If I lower it to the 2 position the blades will disengage again. Problem seems to be getting worse and I am concerned the blades wont disengage at all.
I am somewhat mechanically inclined but wouldn't even know what to look for if I drop the deck.
Any help appreciated.
