I bought the newly introduced Massey Ferguson ZT33 72" Zero turn in June and WOW, has it ever performed. I still have my Kubota ZD21 60 and I hate to use it now (still a good mower - but not a MF). My father usually uses the ZD 21. The MF has more power than I could ever use and I mow a lot of hills and a lot of tall/wet grass. The controls are much more sensitive than the Kubota, which took some time to get used to. Very comfortable to ride. Discharge of grass is great...even, with little to no clumping. *(assuming discharge guard is open). The only negative I've seen is the rear caster wheels on the deck do not rotate 360. They are stationary wheels that only roll forward. I can lift them, but that of course limits their effectiveness. The deck has wheels under it, which help with scalping. I see virtually no scalping with this mower. (Very rare and usually my fault). I like the jack stand better than the Kubota too. It has a removeable jack stand that stores up front (in front of my feet). I then attach it with 2 pins and then it's just like a trailer jack. Very easy and it raises the mower a lot higher than the Kubota. Makes blade access very easy. Just thought I'd give an update on my purchase. I can't compare it to other machines except the Kubota.
