The drive belt for the deck will not last or stay on. The drive pulley at engine is Vstyle on the deck i have a double Vstyle on the left (that drives the blades) and 2 idler pulleys both are flat style. The tensioner / idler that engages is flat style i believe it should be a v style. if you place the belt on the pullies as described on the mower and in the manual it makes the v side of the belt try to run on a flat side tensioner/idler pulley
