Any love for the DR 3 point hitch string trimmer attachment?

My corral is full of DR stuff even though I don't agree with all their design ideas. I have the ATV-mower tow behind primarily for fence clipping. Only problem is that the spring is too light so I replaced it with a chain. Now it just jumps to the side as the deflection bar glides by a post and immediately returns to the path. I read up on the 3 pt and it looks like a good design to me.
