In 2000, I bought an Exmark Turf Tracer 48"/17Kaw. I LOVED the mower and the quality of the cut, but I wanted a bigger/better toy so I sold in and in 2001 bought an Exmark Lazer Z HP 52"/23Kaw. I loved it too and although I was always pleased with the cut, I actually lost a job because the lady did not think that it was as good a cut as with the walk behind. It did "dip" a little on slopes leaving the lines in the lawn where the TT did not. Anyway, I am no longer in the business (it was part time) but I do want a mower for home use. I plan on keeping whatever I get until I go to the grave, but if I did have neighbors who wanted their lawn mowed, I would for a little extra cash. Would you go walk behind again (better quality of cut and lower price) or small rider (more expensive but easier on me as I get older)? Do you feel that a walk behind provides the better cut? In live in N. Georgia and their terrain varies from flat to very hilly. Thanks!
