I am looking at buying a pushmower (maybe self propelled?) to cut some pretty small yards and a couple of not so small ones where the owners do not want my Z Mower or Lawn Tractor running over their grass. Does anyone have any ideas, suggestions, or advice on what brand to buy? Do I need to consider a walk behind instead? I happen to have a Toro dealer and also a Husqvana dealer nearby but am prepared to travel to get the best machine. Lets hear from you all.
