Have you ever actually verified the blade height of your mower compared to the indicated setting? Was it accurate? Since we run the decks canted 1/4" lower in the front, what is the proper way to measure height - front tip of front blade (if you've got three blades), or centerline of deck? Is the measurement you take on a hard, level surface going to give you the same height when you're on the turf? What are your methods???
