That's why I used my carpet pieces on the bottom. I figured the weight of the machine, plus vibrations from the road, would cut through the tarp. Didn't need carpet all over, just on the corners was enough to prevent damage.
Yeah, it wasn't my tarp so i didn't bother. They laid it out and set the machine on it, then tarped the rest. i didn't have to do anything but secure it and put the bungies on
