How do you replace drive belt on cub cadet SLT1554?

Remove the bolt on the clutch. You can get a pair of channel locks on the shaft to hold it. Remove the clutch. Then get you a 4lb hammer and a punch about a foot long and bend the 3 tabs back away from the pulley. Becareful not to hit the pulley. The tabs bend back really easy so you don't have to hit the punch hard. You may have to take the steering arm loose on one side to do this. It takes about 15 minutes from start to finish.
