Me again. it is easier than I thought. Take off the blades. Just remove the shroud that covers the belt under the deck. There are four bolts. Then put the belt around the shaft on the engine side of the shaft pulley. Work the belt into the drive pulley and press the pull towards you to allow the belt to pass between the pulley and the tensioning spring/rod. Attach at shaft pulley being careful to not let the piston compression snap forward with your finger in the way! Done.
