Questions for those that have the ballast box. Was there suppose to be pins included to secure the ballast box to the 3 point hitch? We also bought the iMatch Quick Hitch and that came with a set of bushings. Also included for a second set of bushings for the rotary cutter. However on the ballast box there was no center link and snap pins as well as the snap pins on the sides. I was just wondering if those were supposed to be included.
