I too have ask & search from coast to coast..nothing /forums/images/graemlins/frown.gif but I have seen some home made units on B6100 & B7200 /forums/images/graemlins/crazy.gif
Had the same problem myself a few years ago; solved it by trading the B7100 for a new B2710. And the last time I saw the dealer that I bought my tractors from and who took the B7100 in trade, he told me he had just sold that B7100 for the fourth time. He said the next two buyers were like me; thought it was nice little tractor, but came back and traded up to one with power steering after awhile. /forums/images/graemlins/laugh.gif
If B7100 only had power steering /forums/images/graemlins/shocked.gif than indeed what a little monster it would be..sure would save some hurt on the knuckles.
