These photos so a little of how deep the tractor had to dig to get down to the bottom on the fence across our back yard. About 3 feet. Couldn't beleive that much dirt had drifted against the fence in the 9 years we have been here. Our neighbors was about as deep and they have only been there 6 years. Dug a hole and burried all those sunflowers. My blind horse, Star didn't pay much attention to the tractor. Neither did any of the other horses. I did keep the dogs and cats in the house while it was working so we didn't take any chances on them getting under it.
