Caterpillar 233 Industrial Tractor

Has anyone seen a D2 like this? I have'nt seen another D2 like this other than my own.

I would sure like to see what makes it a "233." Is it the ripper mount on the rear? I wish there were more images on that tear sheet.😕

Bruce, This is the only picture on the brochure. I tried to post the back page with all the specs, but computer wont let me. I could fax back page to somebody if they wanted to try to post it. The local Cat dealer at the time was Shepherd which did these modifications according to the brochure. The D2 I have has same specs but no two speed reverse as listed in the brochure.

Looks like the track frames are 933 length, that along with the two speed reverse, probably a 933 base, engine, trans, track frames, built into a D2.
Is that a hydraulic twin tilt on the blade?

Spec sheet.
