Great photo!
Wow that thing must be used to pull discs 32 ft wide or more, no?
That really is a monster.
Here's (link) a photo I posted here 10 years ago of the equivalent from nearly a century ago, a Caterpillar 'sixty' that used to be shown at California State Fair each year by an elderly guy. I think 2007 was the last time he and the tractor were there. It was a monster (for its time) also, and awesome to watch the old guy maneuver it expertly in tight space.
