To me, it's a huge difference. I've never owned a 322... but the 3hp difference between the 325 and 328 is like night and day, with regard to performance. I'll never buy another 325. Also, depending on what year 325 you compare it to... the 322 uses the older style fine-spline PTO shaft like the Groundsmaster 72. Later 325s used the coarse spline shaft like the 328s. The U-joints are the same... but the early fine-spline yokes are notably more fragile (the part that holds the U-joint to the shaft).oke , thanks. not much difference then.
