I have almost the same model hoe with a complete set of manuals. Can
copy a few pages and email if you need.

You're describing an O ring or backup ring failure in the stearing
cylinder. If true, it should go back and forth nicely with front tires
off ground. This is an easy repair. If that's not it, crack the hose
line on each side of stearing cylinder. Oil should spurt when you try
to turn - this is a poor man's pressure check. If you're not getting
flow - hire a real mechanic.
