I'd like there to be more info on True Tracker as well. I'm running it on a Sunco Guidance hitch (3 point) with my planter and tractor.  After running it successfully for two years I made some planter changes and moved the GPS receiver further back.  That didn't work well at all so I had to engineer a new bracket to put it directly over the row unit.  Now it works good again.  My issue specifically is I do not have a way to manually move the hitch without it being engaged.  I'd like it to be tied to an implement switch so that when the machine is raise it move the hitch to a zero/straight position.
