Well, I recently picked up a used Ransomes 21" for trimming. After using it for only a few days, the motor went. I am going to replace the motor because I really like the machine and everything else on it is in excellent shape. Now as far as motor choices go, I'm not really sure where to go. I don;t want to spend a fortune because I only use the mower sparingly, so cheap is good. I was thinking of either a new Briggs (for about $170) or a slightly used Honda or Kaw. any other input?
