John Deere JX 85 mower?

Hi;you need to turn the fuel off and turn mower on its side and then take out the bolt that holds the clutch arm to the bottom of the mower,next you take the belt and slip it under the bracket and then put other end on pulley ,you may have to bend the arm away from the pulley so your belt will slip on ,then put back together in the reverse order.
