Please identify this tractor

Hi, all.

Need any info on the tractor in this picture, such as the size, well, really interested in the length of the cargo and was hoping to figure it out if I can find the OAL or wheelbase of the tractor.

As you can see, the blade on the back is HUGE! It was on its way to a wind farm in the Mojave desert, in the picture it is westbound on Jawbone Canyon, which runs off Hwy 14 north of Hwy 58 here in California.

My daughter's class at school saw the picture, and they really want to know how long the blade is, so now I'm on the hook!

 

Man, I'm getting all kinds of answers, but I had to resizee the picture down to post it. The original was 1600x1200, and I came up with the below results:

2.375" for the truck wheelbase, 11.5 inches for the blade length. That equals 4.84 ratio wheelbase to blade.
By my math and the larger picture, it's between 95 ft given a 245" wheelbase and 105 feet if it's a 265" wheelbase.

So, a big thumbs up to Winchester Magnum for the best guess, and another big thumbs up for all the help from everyone!

Here's one more picture of another one I saw when I was at the top of the hillclimb on my dirtbike and first saw it, the tiny white dot behind is a full size Ford pickup.

They were hauling these in all day long, must have seen 4 or 5 of them.
