PineRidge,
For the size of a Class III Boomer, makes all the difference in the world having the supersteer. At an incredible 75 degree turn you can't beat it when you get in a tight spot. Sometimes, almost feels like your going sideways....just phenomenal. I bought my tractor used so already had it. I have been told it is a $2,000 option. If I bought the tractor new, more than likely I would not have opted out for supersteer but that decision would have been made primarily from an economical standpoint. From a practical standpoint (and cash is not an issue) would highly recommend supersteer to any considering it especially if you know in advance the type of work you will be doing. I see from your pics that you also have supersteer. I'm sure you agree with the great steering response you get with this option.
P.S. Your "Blue Thunder" has a formidable presence on this forum. Just awesome pics of an outstanding machine !
