I use them to place my Grasshopper in the back when I need to clean the mower's under deck (after every mowing). Once I forgot to remove them before reversing. My mower started moving right over them. They didn't move. Sizes are listed in the ad. So I shouldn't have been surprised by the small size. I bought them because they got such good reviews here. I don't know anything about pads. First time I used them. I wish each had metal grommets so I could hang them on my garage wall. But the price was exceptionally low compared to everyone else. Bought it because of the reviews and the cheap price.
