I have been using my MH871 for about 4 months now and it has been working great. I was cutting a logo yesterday (two words) and the cutter messed up. It cut one side of the weed box, but as it went to cut the other side it went halfway and then closed the box but continued to cut the logo outside the weed box. If there was not a cut line directly in the middle of the logo, everything came out great. Not too sure if anyone else has encountered this. Thanks
