Hi My John Deere 50 is a hard steering tractor, with an extra hard spot about half way through a full turn when turning left. I took off the front nose hood cover and checked the oil level in top steering gear box - it has plenty of oil in it. that's as far as I have gotten. I plan on blocking up the front end of tractor and checking the steering effort required that way. Do any of you have any experience in the repairing a 50 steering system. My 50 does not have power steering. when turning right the steering effort is less. I know old tractors steer hard, and I'm comparing the JD 50 to my Farmall H steering turning effort, which is nice. Any help is welcome.
