I agree that the mower leveling tool is a really great tool to have. It is indispensable. One side of the 54D deck on my new 1025R was over an inch lower than the other side. Either the setup guy did not level it or it got messed up when they installed the mulch kit. 3 hours later, it is all level and set for 3 3/4 inches at the lock setting. What took so long was that at first I was leveling at the uppermost raised position. Well, after getting that leveled and raised as high as it would go, then I tried the lock position and it was not level, so I had to start all over again, since that is the position that I will be mowing in most of the time. Sometimes, I will mow in the HIGH position, which is now 3 1/4 inches.
