Hi all. Hoping to get some help on this one. Saturday morning, got the tractor started to do some bush hogging and the steering was really stiff turning either way. Pulled into the shop and checked fluid. Full and clean. Went ahead and tried driving around. The steering would come and go. Drove it longer then relized it was good turning left but stiff turning right. Went ahead and did some cutting and towards the end of the day it was fine. This happened 2 days in a row. This is a M7040 4WD with 3100 hours. Have kept up with all the maintaince. Also tried the loader when this was happening and no problems there. Any help and advice would be great. Thank you.
