I am a school teacher who has been mowing part time for the last three years. I have between 25-30 accounts. I mostly work by myself except in the fall and early spring. I currently use a Great Dane surfer 22/61 that has about 400 hours. I am going to upgrade to a Hustler 27/60 Super Z. Here is my question. Do I need to keep the surfer or should I trade it in. I really like the surfer but I want to go to a rider. I'm leaning toward keeping the surfer so I will have a backup. I enjoy mowing and I plan on staying in this for the long haul. I need some feedback. Thanks!
