I have a Time Cutter Z4200 and I really am not impressed with it (maybe they have made some improvements):
1. No suspension system so gives a very rough ride.
2. Has mulching kit but does not mulch very well like my old Deere did.
3. Rear wheels project out past the mowing deck just enough to make getting up real close to objects difficult without bumping into them with the deck.
#3 is very important if you have a lot of obstacles to mow around.
