poor engineering
When my CMM1200 arrived from Amazon, the height adjustment was inoperable.I looked in the bottom of the box and found one of those cheap "locking washers". There's a bar that goes from the front wheel to the rear wheel that connects to the height adjuster. The bar had come loose from the shaft it attaches to. To re-attach the bar, one has to kneal on the front of the mower while lifting up on the rear of the mower until the hole in the bar lines up with the shaft. For the time being I re-installed the "locking washer", but my guess is that it will continue to fall off in use. Why Black and Decker didn't put a hole in the shaft with a pin is beyond me. If they can't get the little stuff right it concerns me as to the reliability of the rest of the mower.
