I saw one of thems once. http://www.convertiblemower.com/ is their website. I think they were overall built for larger homeowner use/light commercial use. Most of the mowers with 7 guage metal on everything (its thick) are generally built that way for added durability and employees that dont care about their owners equipment. Now, if you're the only one using it, you wouldnt be so hard on the machine becasue you payed for it, therefore its more of a concern when it breaks down to you.
