Hi. Thank you, but the lever moves perfectly fine. That is not my problem. Whenever I move the lever toward the front of the mower, the wheels do not adjust properly. Instead of moving up and down (which I presume is how it should work), the wheels move forward and rubs against the deck of the mower. I'm not sure if I'm describing it properly. I have not had any problems adjusting the height up until yesterday. Any thoughts?
