Check the condition of the lift cylinders. I know a guy in my QDM (quality deer management) chapter that has broken two lift cylinders on his Kubota. He uses his machine for brush cutting trails and removing buck brush and other stuff like downed trees and brush on people's hunting properties. There is no way out for the debris that collects in the loader tower and it gets between the cylinders and the frame and breaks them. Very hard to even pressure wash the area.
