Just got a peek at the new Toro Z Master that is to replace the 200 series, I think they will now be labeled as 500's (not sure). Was at my local Toro dealer today and saw a 20HP Kohler w/ 52" deck. I guess they will still make the 100 series with the 52" but this was the "big" series. Looks quite a bit different with a black floorboard area that hinges from the rear for deck access (it actually clears the foot assist this way). Also, moved controls from below/in front of seat to the left fender for easier access. That area behind operators legs now has an oblong open "box" that would hold a sub-sandwich or something....not sure exactly what??? It has thick control arms that are probably twice the diameter of previous models. Most of these things are cosmetic but the biggest functional difference is the deck. The SFS has been ditched for the new and improved Turbo Force that really looks like an improvement. It is 7 guage all over and has a 7 guage reinforcement on the front edge of the deck. Kind of impressed by the fact that Toro was able to bend the front top deck edge (rather than weld) even though it is 7 guage. The deck is also 5.5" deep (kind of sounds like they learned a thing or two from sister/brother Exmark and the famed UltraCut) and offered in 52", 60"(like Exmark) and 72". The blades are now 1/4 inch and the discharge shoot is rubber/plastic. That's all I can recall except for the rollbar that has been added. It can be removed altogether with a couple of bolts (4, I think) or just folded down with a pin type setup. Prices were mentioned to be $75 to $400 more depending on the exact model, but the Toro rep made it sound like a deal because the ROP is usually a $500-600 option, so you get all the improvements and the ROP for an effective savings!!! All in all it looks like the Toro fans will be in for a good machine. Too bad I am quite happy with my mean yellow Hustler Super Z that has many of the same features already plus an air-ride seat for a whole lot less money. Not to mention the best warranty in the industry! Check your local dealers as this was a demo they will have for the next week.
