# Scraper cross slope appears to be the opposite of what it should be.

<span dir="ltr" style="font-size: 14pt; font-family: Helvetica, sans-serif; color: rgb(0, 0, 0); font-weight: 400;">**Symptoms**:</span>

<span style="font-family: Helvetica,sans-serif;"><span style="font-size: 14pt; color: rgb(0, 0, 0); font-weight: 300;">When T3RRA is commanding a cross slope tilt to one side the scraper blade is doing the opposite. iGrade is showing a current cross slope % as positive when the implement is rolled to the left, and negative when tolled to the right. Reversing hydraulic hoses in the remotes does not help the problem.</span></span>

<span style="font-family: Helvetica,sans-serif;"><span style="font-size: 14pt; color: rgb(0, 0, 0); font-weight: 400;">**Cause**:</span></span>

<span style="font-family: Helvetica,sans-serif;"><span style="font-size: 14pt; color: rgb(0, 0, 0); font-weight: 300;">The implement GPS mount direction has been changed to ‘Backward’ in the John Deere display. This causes receiver TCM readings to be the opposite of what they should be. </span></span>

<span style="font-family: Helvetica,sans-serif;"><span style="font-size: 14pt; color: rgb(0, 0, 0); font-weight: 400;">**Solution**:</span></span>

<span style="font-family: Helvetica,sans-serif;"><span style="font-size: 14pt; color: rgb(0, 0, 0); font-weight: 300;">Set implement GPS mount direction to ‘Forward’ if the receiver is facing forwards.</span></span>
