hopefully this month i will be upgrading to bigger mower. currently using a 36 wb, 26", and a 21". while working in an upscale neighborhood, after a weeks worth of heavy rain every afternoon, i was forced to use my 21" on several lawns as my 36 ruts badly. i noticed while there several companies using standers with a lot of success. are the standers better at handling wet lawns than a ztr? whats the top speed of a stander?
