| I am having the absolute exact same problem. Tractor steering is jerky to the right and normal to the left when hyd oil temp is 136 degrees or higher. 135 degrees or less both are normal. My john deere dealer claims to have completed the calibration several times with no change. They now believe there is something wrong with my steering motor and have sent it off to Ames Iowa to be tested. I do not feel this is what is wrong. I will update results when they get the motor back and let you know what that changed. I will have them check the o-rings if the motor repair does not fix. Please let me know what you find out with yours if you do! | |
