I ran a 30' last year and figured out that the head did not flex as well if you pushed it all the way forward. I always pulled it back 1 number and felt like it did a better job. The only head we had this problem with was a 972 with a 871 adaptor. Maybe your springs are not set right. My first thought is they are to tight and are lifting the head up to far. Did you set up the head or the dealer. Check and see that the white bars between the springs and the head are lined up correctly. To do this the flex needs to be locked and the cutter bar about 6-10" off the ground. If they are out of wack then you need to look in the manual and reset them and the flex springs as well. Hope this helps.
