I just bought the new Massey Ferguson ZT33! Power....Wow!! I lined up my Kubota ZD21 next to it in tall, thick wet grass and the Kubota would almost stall while the MF would power right through it. It's got the 72" deck. Appears to be very well built. Only time will tell obviously. Much more ground clearance on the rear...good for dropping off edges of banks and not getting hung out to dry.
