Craft...It is an interesting set up. The grader blade (although all manual adjustment) Vee's, U's, straight blade or angles either side. The Vee blade up front is for ???. I suspect that it might be mainly to knock down berms or spreads ahead of the grader blade. Height settings are adjustable by the arms or links (grey in color) that run down each side (just off center). This is the adjustment that I have not had time to work with, and am hoping I can find a manual or talk to someone who has used this attachment. I think it has much possibility......if it works!!!! LOL
