Hello Everyone, Last year, I purchased a Ferris 1500 ZTR Mower for use at home. I mow about 5 acres, and I am really glad I found this forum at the time, and bought a commercial mower. My dad lives on a regular neighborhood lot (about 1/2 acre) and mows thick St. Augustine. He is getting tired of his big box push mower, and asked me for advice. When I bought my mower, I only really looked at ZTRs, so I am not real familiar with the walk behind models. Would you all recommend some good options, or tell me what I should be looking for in a walk behind? What are some of the better entry-level commercial grade units? I'm sure any of them would be overkill for what he needs, but it is always nice to use commerical grade equipment, plus it should last him a long time. Thanks for your help!
