I recently bought PEC and have found an issue with my attachments on my JD 770. because of the shape of the lower 3 point arms I can't hook up to all various width attachments. Since PEC carries the angle of the arm back and doesn't pivot I can't set my arms at a single position and pick up both my widest and narrowest attachments. Unfortunately that's the two attachments I hook up the most. I will say that when you can use it sure is nice, but there's no way I'm going to be taking the PEC on and off to hook up an implement. For me, if I can't use it on 100% of my attachments it's not an option. I need to figure out what it will cost me to alter my outliers vs just selling my PEC.
