Have any of you had trouble with your old style surfer leaving a little windrow right at the outside of the chute? My deck is clean, I have new highs and it still leaves a little windrow. You can see a little tornado action at the back of the chute and the grass just swirls around. This is on dry grass that shoud not be doing this. I did try a gator on the right side and that seemed to help a little.
