I'd like to hear from those with actual experience on "demanding" lawns (warm season turf demanding a precise cut on non-smooth, flat surfaces). We have a lot of Bermudagrass sodded lawns here in new subdivisions that are built on rolling, uneven ground and usually a bigger deck mower won't give an acceptable cut, but I'm looking for something bigger than a 21" push mower to handle these. Right now I reject anything with any size at all that can't be cut with a Lazer Z. I wouldn't mind mowing them with a wb. My Exmark 48" deck cuts great, but still can't handle some of the undulating terrain well enough to be used. Any suggestions on mowers that give a great cut on properties like these?
