Hey Greg, I looked at the photo of the rear of your tractor and it reminded me of something....
My swinging drawbar has a big gouge in the end of it that was made by my rotary cutter's blade. That may not be a problem on your SQ72, but I backed my cutter up a hill and when it raised up, WHACK! WHACK! the blade hit the drawbar. I got under the tractor and moved the drawbar to it's most forward adjustment and I haven't had anymore problems.
I may be the only one who has ever had that problem, but it's something to be looking for. You don't want to have any blemishes on that beautiful new tractor or cutter. /forums/images/graemlins/cool.gif
