That doesn't look bad. Is your tractor 4WD? You could just back into the parts that worry you instead of driving across the face.
Mark -- my tractor is 4WD. But, more than once, I've had to use a winch to keep it from sinking too far into the pond.
Just last week I was mowing with my Cub Cadet lawn/garden tractor, which mows about six inches outside the tire lines. Since you are just down the road, you know we've had a little rain lately. The mud was pretty slippery. I slid more than a foot sideways to the the pond edge, with the left side well entrenched in the the mud. The friend who dropped off the machine in the photos above, just happened to be coming in my driveway at the time, and saw me. My wife was watching from the kitchen window (all very embarrassing). We dragged the Cub Cadet out, and I stayed at least 18 inches from the pond edge for the rest of my mowing experience that day.
