I have a Shibaura Sd2843t. And I was using it pretty hard the other day! It has front end loader too. But the lift arms on the back starting jerking (moving up and down about 1/4 inch) but makes the whole tractor jerk with the box blade on the back. When you move the lift lever it doesn't jerk until it stops where you want it then starts jerking again. But if you lift all the way up it doesn't jerk!! So I kept it all the way up yesterday so now when the tractor is not at full throttle the lift arms will slowly go down! So can anyone help my situation??

Are you talking about making sure the lift lever that is by my right leg isn't loose? And I don't know if it has lift cylinders cause its all internal! No cylinders on the out side of arms ....

There may be a rod going from the lift arm to the control to sense how high the arms are. The lift cylinder is in the housing under the seat. ....
