Massey Ferguson 7700 autosteer ready

BL08,
The calibration in the dash you are performing will only affect the 4wd and the Difflock kick out. You will need to perform the WAS calibration as well as the Wheel angle center value. I have attached a screenshot from EDT of the calibrations that will need to be performed. I’m not sure how much labor/time you want to spend but theoretically you could adjust your WAS (since most folks don’t have access to EDT) to reach the 0 reading by manually turning the sensor in the axle. I believe the holes are slotted on the sensor for small adjustments (this is why a calibration is needed). If the dealer is going to be doing the calibration please also have them perform a “curvature test” the wheels of the tractor need to move smoothly from left to right and we should see the WAS count increase smoothly as the wheels turn (by themselves during the test). This will verify everything in your steering system (WAS, PVED, and SASA) are working correctly.
