New TB230 and advertised as having 9 cutting heights. Well in reality, 5 post positions for the hole in moveable arm to snap over, the intermediate posiitons are too small for the moveable arm to drop in and secure itself, so the arm sits atop the posts and as you move the mower the arms just slip fore or aft negating that cutting position. Anyone have a solution, I am considering taking my Dremel and a cutting disc and slotting the arms, fore and aft sides, to correspond with the fixed post height and see if the arms will now hold in position. What do you think?
