i am close to closing a deal on a z950 with 60 mod deck. i see they are over 1400 lbs. current users of z900 mowers how are they handing on postage size lawns and small commercial properties? are they smooth? or tear easily? i know when i demoed the scag cheetah (it is in the same weight catagory) i never tore anything. the same lawn i have had many exmarks and a scag turf tiger on there all which tore grass. so i just want to know from someone first hand what thier expierence has been with them.
