Jerky MMM hydraulics?

[JayOrange]

I have a BX2370 and recently removed and put my MMM back on. I'm not sure if it was like this before but when rising it up, the very last bit is jerky if I'm doing it too fast. I try to move the lever slow the entire time now and it seems fine. But the last bit is far more sensitive to this then the rest.

Is this normal? Did I reattach the shaft wrong?

I also notice that when I am lowering the MMM down that only 1 wheel hits the ground on what I believe to be a flat surface. I know that I've lowered things all the way because I also have a box blade installed that hits the ground and won't go any lower.

One last related item is that I thought when I first operated the tractor (before removing and reinstalling) that the MMM would drop all the way down before the box blade would move. Honestly, I could have been wrong in that assumption, but it now seems that the MMM goes maybe 75% of the way down and then the BB moves. Now, I'm going to start taking the box blade off to mow anyway BUT it makes it so that when mowing with it on the box blade isn't sitting as high as it can go. I just want to make sure this is how it should be responding.

Ultimately, I don't know what to really expect since it's my first tractor and I don't have the best memory of the way it was when I got it. Any and all help appreciated.

Thanks!

The box blade and mower will drop at the same time as they are controlled by the same mechanism.
The 3-p will drop and the mmm link is just behind the left rear tire.
It would be best to drop the blade when using the mower.
You can lock the mower using the knob below the seat set to top. It may need adjustment by turning the bolt on the arm left rear tire.

May need to exercise the 3-p to get it from jerking.

If all your scalp wheels are set the same as fronts are the same and rears are the same, the only thing i can think of as to why one wheel would hit first is you don't have one of the lift pins latched into the mower deck correctly. This could also make it appear jerky when lifting as it is wobbling. Might want to check and make sure the pins are both secured in the slot correctly.

The mmm lift mechanism is adjustable behind the left wheel and attached to the 3 point. The rear 3 point will drop at the same time as the mmm.

I dont see how you can mow with any ground engaging 3 point equipment. You will find that mowing will be MUCH easier on you without anything on the rear.
