How about something like this?

http://www.kunzeng.com/ No idea what the quality is like, but have seen other companies that make these types of mowers. Usually farm dealerships have something like this that they sell. Shortly line equipment styles that the larger dealers have. Think Farm Fleet puts one out, not sure who their supplier is. Perhaps Land Pride has one or Woods? Not sure if Bush Hog still makes theirs or not?
