If you have the PS unit, or torque motor under the dash, you may have a a PS problem. It could be the torque-motor or something in the hydraulic supply to it. Tractors with factory PS have a "regulator safety and flow control valve", basically a relief valve and priority flow divider so the primary goes to the PS and the rest to the balance of whatever hydraulic system you have (there are 4 or 5 different versions for these tractors, depending on how your tractor is equipped). If the rest of your hydraulics work, I'd suspect your problem is one of these two places. Mine is an aftermarket Charlynn PS, so it has an external priority flow valve and not one built into the system. The torque-motor is added into the steering shaft that runs along the left side of the motor, and not under the dash.
If you changed the gears to a manual set of gears, it would steer easier, but have more turns "lock to lock".
added: I just checked my parts breackdown and they do not show a different ratio for a PS equipped tractor, but do show a different worm for the Farmall vs. International. Of course the mating gear is entirely different due to either a direct hookup tricycle tractor or the Utility steering arm. I replaced mine and had a hard time finding the right gears. Finally got one from a place south of St. Louis, don't recall the name, but a big IH used parts place. A salvage in Nebraska also had one, but wanted to ship the entire front bolster which probably weighs 300 lbs.

It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
