Caption: Classic factory shot of a Caterpillar 631A motor scraper. The 631A was a nice, businesslike looking machine. Telltale spotting feature are the twin air cleaners.⁣

Caption: An HD-41 with U-dozer, ‘soft’ cab and Kelley ripper. In some materials the tip velocity of the ripper exceeded that of blasting, making this attachment particularly attractive to mine and quarry operators.⁣

Caption: Photographed in Queensland, Australia in 1982, this Fiat-Allis 41B is waiting to have some repairs carried out on its equalizer bar (as can be seen from the slight ‘nose down’ attitude), not an easy job to carry out in the field on a tractor of this size.⁣
