On assembly the 2nd fork from left. I could not get my socket on the nut because the lock bracket was mount ever so slightly too low. The tines are held in by only 3 threads as the threaded end of tine is too short. POOR engineering.. It would be nice if there was abit of a bottom and /or sides to hold some loose material. It works well for hay/straw packed manure. As for durability that is to be seen as I have only had it here for a week.
