The 4 bolts on each one are for controlling this. Set your 3pt arms level. Set the plate steel of the 3pt arms to be perfectly vertical. Now use the 4 bolts on each PEC piece to get them plumb both level and vertical. That should take care of it.I purchased a set of these but when I raise and lower the 3 point they change pitch sideways???? any input ?
I believe that you are correct. I have always thought that they were designed that way in order to give greater ground clearance when raised all of the way up. Just a little tilt forward raises the back of a long implement considerably. Then when you lower it back to working position it is level again. This lessens the need to adjust the top link so much. At least that makes sense to me.I know this is an old thread, I came across it while researching Pat's Easy Change Hitch.
Isn't what the OP describing just the nature of the 3 PT hitch arc? The arms are moving not the PEC. The PEC are just following the arms.
I assume this is why all the links have articulating balls in them.
