Yep, I got my hands on the Super Z Diesel last week. That thing is BAAAAAAAAAADDDD!!!!!!! It felt bigger and bulkier than mine, which it probably should have. Mine is a 60" and the demo unit was a 72". I was very impressed with the torque and the noise the unit made. I put it in the tallest grass I could find, let the deck down and turned on the blades. The mower didn't even know it was cutting grass. At Wide Open Throttle it seemed to be quieter than my 25hp kawi. Other thing that I noticed was that the blades engage much smoother than anything I have been on. It's almost like they have to spin up....I guess I don't know how to explain it, but it was a big positive. When I engage my blades it's like they hit all at once, but this wasn't like that. This was smooth. Anyway, just wanted to say that the mower is sweet and if you get a chance to demo one, give it a try. PJ, is there any secret to how the blades are engaged on that mower Vs stock 60" super Z??
