I agree the stub is a better way but I have plenty of guards for it laying around I don't have much trouble cutting anything off The problem I run into is when I'm planting corn and the hay gets put on the back burner It's not important to me when I have my crops to put in first. My first cutting this year was after some folks had already got thier second off. I'm not sure how I would adjust the register you speak of. Is that in the actual wobble box itself? I don't see where you could move the actual placement of the box
