That's strange. Do all tractors have this issue or just Yanmar? I know my JD 310SE backhoe doesn't do that.

This is in the manual. It's not correct. It should say at lower rpms the power steering is disabled. I certainly wasn't operating with a load, at idle. Today I'll do a test and a video.

Just got off the phone with Yanmar Tech Support.
They do acknowledge there is an issue and it is being addressed. They took my name and number and will get back if/when an engineering solution is available.

I hear you but this still isn't right.

YM2500 now YT 359c
I have the same issue, and have definitely experienced a little bit better response when the RPMs are raised. However, it shouldn't happen at all. And it certainly shouldn't have to have the RPMs raised up just to turn the steering wheel in a fluid motion. The whole point I bought the Yanmar was so that I would get better engine response exactly when I needed it. So having the a/b function where I'm at lower RPMs when I don't need them, but now I have to manually have the engine at high RPMs just to turn the steering wheel?
I had a different brand of tractor before this one that had other issues. But power steering was smooth as glass. Like the full power steering on a 1984 Oldsmobile Delta 88. One finger steering control of the entire tractor was possible. I've experienced this issue with or without load idle partial load hay bale bucket full of dirt, it doesn't matter it happens and there's literally nothing you can do about it other than raise the throttle up even though you're already in gear and you're trying to slowly turn. It completely negates the AB function.

Yea it feels like a relief valve is by passing
