That Country Clipper Boulevard looks to be a pretty decent machine. What's the problem with it? Only thing I see is the smaller rear wheels that would give a rougher ride, especially on my yard.
If I could figure out the zero turn operation, and the financial part of it, I'd be looking at a Ferris unit with the bigger tires and suspension setup. Our city department has a couple of those, beat them to death, and seem to really do the job.
