Thanks for your reply, Tommy. I will check those tire pressures right away. When I stand dead center in front of the tractor, at some distance, I swear the top of the right tire is canted out more than the left one is. I'll try to make some measurements too. Do you happen to know what the angle is by design? I tried to do some measurements on a flat bench, just on the castings during a repair job, and it looked like about 3 degrees.
