Yes, I've seen it. I was doing a small mulch and cleanup job at one of my accounts yesterday and this fella pulls up with an enclosed trailer to get some air for his tank. He put his money in the vacuum side and looked perplexed! I was sittin there takin a break and just looked at him and shrugged! Anyway, I went over to see what he had in the trailer and I couldn't believe what I saw. It was some sort of standon mower but it had eXmark all over it. Apparently, he had modified a floating deck hydro walkbehind. It had a seat with a massive shock absorber and I believe it folded up. Believe me, it was a very professional modification. He formed a platform and moved the wheel motors back some. He put really large tires on it and a small weight on the front. He had the stander type controls fabbed too. He also had some linkages to pull extra decks. He told me his total cutting width but I forgot. I hope he gets on this site, I did tell him about it.
