Here is a problem with those roll back haulers; when my dealer delivered my tractor on his roll back trailer, the piece that drops in the back to keep the truck from raising up ground into my concrete driveway and left a nasty mark. I'm not at all thrilled with that. The only way to properly repair that nasty mark would to jack hammer out that section of concrete and pour it again. Being that it is 5000 psi concrete with 6 gauge wire, 8 sticks of 20' rebar, and is 12'X20' section, I'd guess that to have it properly repaired, it would cost several thousand dollars. That's besides the inconvenience of having my driveway out for a couple of weeks while it is repaired.
I'd pointed out this damage to the driver and asked why he didn't just use a 2x4 or something under that stabilizing drop brace, and he told me that he's tried a piece of wood before, but the truck wiggles and dropps off of the wood causing more damage. Unless it can be loaded and unloaded off of my driveway, or they can bring a large thick rubber mat, I will not ever allow another rollback in my driveway.
Just something to think of. /forums/images/graemlins/mad.gif
