I have a 25ft honey bee swathing front on a new holland hw 340. I mainly swath cereal crops in front of the silage chopper and some drought affected summer crops and of course have to cut low as possible but the fronts sags quite a bit which makes life hard cause each ends digs in. It is a older front so they meant to have that sag or not? Heard few blokes say usually do have a sag in them. Also what's best set up for wheels I can put on each so it can float along the ground a lot better?
