Great post. I have gotten some great info from all of you guys. I own a company that performs repair and renovation services for REO or bank foreclosed properties. Some of theses properties have been vacant for several weeks or even a month before they are mowed( by us ) during repair and rennovation before being put on the market. We also maintain the lawn areas of properties until they sell . What would you recommend as the best brand walk behind?? Hydro or gear driven?? I have found a Kee"s hydro that was a demo unit 52" 17 hp that is for sale for $3100.00 Is this a relable brand?? Thanks for any input and assistance.!!!!
