....hmmmm.... Based on another post, I think the 47" snowblower that bradkramer was kind enough to measure is different from the snowblower I was referring to. The 47" blower for the current x500 series is belt driven. The version for my x575 (predecessor to the x700 series) is PTO driven. As I understand it, this same blower is used on a number of different current and recent vintage large-frame garden tractors and SCUTs. I believe (again as I understand it - I am new to John Deere hardware) the blower is near universal in its application and the quick hitch and PTO shafts are based on the tractor frame being used with this blower.
So I'm still interested if someone would be so kind and to let me know the spacing of the skid mounting holes in this blower I would be most appreciative. Thanks!
