Jeff,
The handle is hollow. It has a long rod about 1/4" diameter with threads on one end, and a 90 degree bend on the other. The 90 degree bend or hook is used to catch the teeth on the lift ratchet. The threaded end has a spring over it with a threaded steel button, which is what your thumb pushes to adjust the lift. If you have no more ratcheting then the rod is either stuck or the steel button unscrewed from the shaft. If the rod is stuck then the lift shaft might be bent preventing movement. Bending usually occurs while snow throwing because of the force needed to lift the implement.
Is the steel button in the hole or is it missing? Has the rod fallen out of the lift arm?
