That's strange. Do all tractors have this issue or just Yanmar? I know my JD 310SE backhoe doesn't do that.
Rev it to 2530 and see if you get the same result. The YT359 max RPM is 2530.
Yea it feels like a relief valve is by passingI 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.
