I just picked up my new Ferris DD 48 in. walk behind! I love this machine. I tested it in my side yard and it leaves a nice cut. I was concerned that Ferris doesn't offer a hanging/floating deck in the 48in. model but I think that if you are going to scalp turf it is going to happen whether you have a hanging deck or not. The only disadvantage I see is difficulty in changing deck height on the job. Overall I reccomend this machine, very well constructed.
