I used this in the fall of 2015 for spreading fertilizer and was very pleased with the design of the 'apron'. If you were in the middle of a plot you could fold the apron up (I used small clips' and it would do the preset width that depends on the spreader. the Agri-fab has about 12 feet.
When you are edging on the left or right you fold down that side. I wish would have had one of these years ago. Also if it is windy you can control the pattern.
