have a 8ft massey fergeson disc mower. seems like it is hanging up way too much on the end. it used to not do this. i could mow through hay that was already cut and not hang up. heavier thicker hay seems to be the worst mowing. morning dew is bad too. i have put on new blades took grinder and smoothed any nicks or gouges where the hay might catch. angled blade up and down. pushed it to both sides. the hay fields look to be cut even. just have to raise blade to clear the grass. only thing else i can think of the diverter is getting worn out. its not bent or ripped up. been thinking about welding some small wings onto the old ones that are on the diverter. any more guesses of what the problem might be? thanks
