Hello, I have a Cub Cadet 2000 Series, Model 2155. 15 HP Kohler/46 inch deck. I'm having height adjustment cutting issues. Seems as if, the lower I set the cutting height the faster the blades turn. I would think, the deck blades should spin at the same speed no mater what cutting height is set. I normally mow/cut on setting 4 (4 inches). If I set the mower deck height setting to 3 (3 inches). Seems, I have more blade power. I purchased a brand new PTO belt and installed it. No difference. Still does the same thing. There is no Belt tensioner pully for the PTO belt that I see. There is no PTO belt "adjustment" to tighten Nor loosen the PTO belt other then the deck rod release arm. The only belt tensioner pully is located on the deck it self. Can the Belt on the deck be causing these blade speed/cutting issues? Any advise or solution to these issues?

Before I go, I like to give Thanks to the people from my last post I created (I need help with a Cub Cadet 2000 series 2155?) I see no delete/remove Post button to remove that post.
