It has 2 pusher bars between the back of the deck & the chassis. Wide mounts onto the deck, and a ball joint onto the chassis. I think there is a link to the diagram earlier in this thread. Looks the same style as the mounts on my Xfactor deck, but the Ferris ball joints look to be more precision made. I do have quite a lot of slop in the ball joints of the Gravely but it still doesn't sway sideways like what GMLC is seeing.
