I just got thru demoing a mini Z(23/52). Wow, great piece of equipment. I plan on purchasing a Super Mini Z(25/52) in the next 2 weeks. Mainly due to the suspension seat and mower HP for little to now more money. I plan on nothing but mulching with this machine, the demo was a side discharge so I could not compare the mulch cut, but the SD cut was great. Here's the Questions. What's new on the Super Mini Z's this year? I heard a rumor of larger tires.... Any place online for parts? How does it mulch? general feedback? any pros & cons. I do all residential. 15000 sf+.. This will be my first Z. So any tips etc for the newbie Z owner is appreciated. Thanks!
