I looked at 9660 WTS on the JD website for the UK. I see JD offers Slope Master and Hill Master for the 9660 WTS. Will JD offer those options for the WTS on this side of the pond? I have been wondering why JD doesn't make it an option for the STS. What are your guys thoughts on the loss out the back on sloping ground with the STS? Do you think the self-leveling shoe or a leveling device for the STS would be a good option to have for some of us whose land isn't level. Would a leveling shoe or other device be worth it? JD and Massey are the only ones that don't have some sort of self leveling shoe or other grain saving device.
