This thing is worth its weight in Gold. This is the most economical one I could find in this style. It works freestanding by placing your other foot on one of the pedals, but it is not very effeicent and you will bend the frame eventually. Mount it on a piece of 5/8” or 3/4” plywood 16” X 24”. If it is going to be freestanding, put it in the middle, if shoved against a wall, mount it all the way to the front so you can swing our foot. If you have extremely big clod hoppers, you will need a little more then 16”.
