The draft follower rides directly on the rockshaft cam. The portion of the draft follower that contacts the cam will do a 1 to 1 movement on the roller if the roller is directly across from this point. This is D or depth.
If you move the roller down the draft follower, LD, then you get something less than 1 to 1. It may take twice as much rockshaft cam movement to get the same roller movement as above when in D.
In L or load, the roller is so far down the draft follower that it is only the movement of the draft lever arm that can move the roller. The cam will have little if no effect. The roller is almost in line with the top of the draft lever arm. In this position, draft will have control of hitch position. (Height) That is why the dash lever cannot control hitch height, only full up or full down. The cam cannot provide any feed back to cancel and make the hitch stop.
The draft lever arm is controlled by the load sensing shaft that actually bends (deflects) when a load (draft) is placed on the bottom arms.
The load sensing shaft seals are leaking on my 4010 and I plan on changing them today. Maybe photos tomorrow.
