I noticed recently that when I pull the lever toward me to operate (raise) the cable unit that lifts the front blade it would hit the opening of the cage on the back of my brush guard. So, I could cut a larger opening in the expanded metal so I could pull the lever toward me more, or could I adjust something to "tighten" the lever up?? I am using the inside lever which operates the spool on the right side of the cable unit. It never use to hit the cage. I am sure is has just worn some. It still lifts an empty blade well - just needs more pull when the blade is full of dirt. Since it hits the brush gaurd I can't put enough pressure on the plates to lift a heavy dirt laden blade very well. Is there an adjustment I can make to return the lever to the way it use to be without cutting a larger hole???? Thank you.
