Hard steering? Possible but not likely. My old M48 steered with one finger. That was six decades ago. The double lever jerk steer has been gone for at least that long. My backhoes steer even easier. It’s hard to believe the commies couldn’t do a passable job of copying a steering system.
I didn’t mean effort as much as precision.
A lot of those hydraulic systems are touchy and easy to get out of adjustment.
