I have a 18.5 HP Craftsman Lawn Tractor, model # 917.274811. It starts fine but the mower won't engage. The attachment clutch lever seems to have the same tension, and the drive belt seems fine. I've looked and can't see any obstructions. Any ideas?

It is a simple mechanism, clean the deck and levers WELL and see if idler (tensioner) is moving. The answer is there somewhere.

remove the deck, clean, inspect, and lube where needed.

Don's advice is sound. I would also check that the engagement cable is moving freely when the handle is moved. Make sure both cable ends are attached. Clean cable well and manually move cable to make it move freely.
