Was at a local farm and home store today that happens to be the local dealer for Ferris. I got a up close look at the 3100Z and was really impressed with what I saw. If I was in the market today I would defiantly demo one. But I have to admit between Scagg, Exmark, and Ferris it would be a tough call. I also got a close look at the Ferris Hydrocut 36 inch WB. It had the most interesting controls I have seen. It was molded plastic "blocks" next to the hand grips that your thumbs sat in. You could move the blocks up, down, and back with your thumbs. Does anyone on here have any experience with this system and is it comfortable and practical to use?
