My worn out 9n is able to struggle thru 3 foot grass and a 5 ft brush hog. You might want to check your blades. I had trouble mowing last last and found the blades were nearly frozen up on the large pivot bolts and were dull. After lubing up those pivots and sharpening, I am now able to mow better than before. I do have to keep my hand on the lift for the really high grass.
