New to us tractor 9530. in any other tractor (9220 and 9410R as well numerous other John deere tractors ) i have been around in order to turn the mapping on or off you would have to hit the detend on the scv. This tractor will turn the mapping off in i flick the scv to cheat implement out of the ground it will turn the mapping off. i switched the scv number on the 2600 to see if it was a problem with the scv switch and it did the same thing with the number II scv. anyone run into this issue. i believe all documentation to be correct just using tractor for tillage a the moment.
