Hi, I'm going to be buying a new zero turn and I'm torn between the John Deere z425 with the 54" deck and the Ariens Zoom XL 54. They're both $4000 and the boss says that's as high as she'll let me go - not a penny more. The only advantage the Deere seems to have is the separate pumps and wheel motors. The Ariens has a welded deck and frame and kawasaki motor. Does anyone have an opinion on this? Thanks.
