...........Make sure when you add the concrete blocks you install a 2 x 4 wood block to lock the concrete blocks into place. The tray is not wide enough to add one more block. If you hit a bump, the concrete blocks move, fall down on the plug which is turning, stops it from turning, and tears the heck out of your lawn if you do not notice it quickly, do not ask how I know this. /forums/images/graemlins/blush.gif I also noticed you will have to tighten the plugs on the turning wheel after use as they loosen up. I use a screw driver to remove the dirt from the plugs before putting it away. Good time to take care of any loose plugs and to grease it up before the next use.

You know that I was going to ask for a picture, so please post one showing the blocks and the wooden block. Thanks Junk.... /forums/images/graemlins/wink.gif
