Yep I completely stole your idea. Worked pretty good, especially going uphill. It's not hard to unroll by hand if it's fairly level, but it's nice to be able to park the tractor and know the roll isn't going anywhere. Make sure you use staples and have a helper. There was very little wind when I installed but the slightest breeze will blow that stuff all over. It rolls out pretty straight, but after it's moved by the wind it can be a difficult to get it straight again. Seems like no matter what you do there ends up being a few small ripples in the fabric after the rock it dumped. We had it placed very well and stapled, but you can't possibly get it in contact with the ground as well as the rock does.
He reverse spread the first load and then after he could drive straight on it without starting or stopping he just drove forward and spread. No sharp turns though. It would be best to reverse spread if possible, but he would've been backing up a hill and turning with my driveway. I watched closely and driving forward on it didn't seem to hurt anything, but the ground under it was well compacted. The fabric was affected more by the rock spreading on it than by the truck driving on it.
