My 1954 JD 40 standard is very hard to steer. It requires a little less effort with a tiller mounted. Is there anything I can do or check to improve the steering?

Fred

My cyber diagnosis would be that there is a high probabiliy that KB has the answer. If you take the top cover off the gear box and find dust blowing around and the thing is full of steel chips and fileings you went to the right spot. If you decide to replace the bushings and seals also, I have a thought for you on lube. After rebuild, I filled my gear box with stuff from JD that they call corn head grease. It is a thin grease formulated for things like gear boxes in corn heads. You will never have to worry about the gear oil leaking out the bottom vertical shaft of the box again. Good luck!

We had the same problem on our 40. Found that there are 2 pins that ride on the worm gear inside the steering box. The bottom oil seal went bad and without anything to lubricate them they wore into an odd shape and there would be a spots in the travel where the steering wheel would just "lock" up. Anyways, long story short we replaced the pins (yes you can still get brand new ones from Deere) and put new seals in them and you would swear it has power steering now. Although, Dad just claims that it is just the extra muscles that we developed trying to control it with those wore out pins.

Fred, have you recently purchased the tractor? It could be someone has the adjustment screw too tight. (the one on top of the steering pedastale) If not- you will have to check all moving parts for something binding or worn out. Usually these tractors steer easy because everything is worn and loose.
