I am looking into a used 36" walk behind mower for backyards with small gates. I'm looking into Exmark, Scag, or Hustler, primarily because of dealer support in my area. My primary concerns when buying a mower are cut quality, ease of use, and durability. I will mostly be mulching St. Augustine, centipede, and weeds. I also need it to be able to handle wet grass well. Which brand and model would you recommend?
