Ok thanks. What I should have said earlier is most of my lawns are around 5,000 Sq. Ft. And I only have two over 10k which are about 15k and a 17k.
Those are some small yards. Why no just step up to a 30" Toro. But if you want a 36" Toro or Scag would be you best options. Though Toro is more well known for its mulching performance. I don't know how many lawns you have but you can't go wrong with a walk behind mower with a sulky. Also be sure to consider dealer support for parts and labor if you need help in that department.
