I have an XR4150 open cab, shuttle. Note that this is not a power shuttle. You must use the clutch. I also use a tiller, subsoiler, rotary mower, ditch bank flail mower, FEL with forks, hay spear, bucket, and grapple. I like my shuttle. I am used to using the clutch. Modern clutches are built better and last a long time if run right. I felt the shuttle was right for me. That said, if I was doing mostly FEL work than the HST might be better. My mower is HST, but I like the greater power pulling up the hills. As far as the trans, it is 16 speeds. It can go slow enough. I would have loved a power shuttle but not available on this size tractor. Make sure you test drive any and everything. I like the way I sat on the tractor, the pedals, and controls. If it does not fell like you can stay on it for several hours, find something else that fits you. For most of use this is a long time investment.
