In the 1930s and 1940s, LeTourneau were prolific in their output of highly informative literature. Today it is highly collectable and hard to find. This selection from the authors collection includes a 1935 publication of cable control units. None of the others shown are later than 1947.
Otto Kuhler (1894-1977) was one of the most prolific industrial designers of the 20th Century. He was responsible for the design of more streamlined locomotives in the USA than all the other designers combined! He also found time to design for LaPlant-Choate and Allis-Chalmers
Industrial design in toy form. An early 1950s toy from Australian manufacturer Boomaroo. It is not a far-flung creation from someone’s mind but an actual machine (a LeTourneau Model C Tournadozer) made from real steel. Although the plastic driver figure went missing quite quickly, the toy was very solid and functional.
If you were a junior earthmover growing up in the 50s and had one of these, you had it made. A 1952 Doepke Heil “Heiliner” motor scraper was a highly sought after Christmas present and good examples today change hands for a lot of money. The toy is all steel with accurately treaded rubber tyres. The real machines tractor was styled by Raymond Loewy.
Raymond Loewy (1893-1986) was heavily involved with International Harvester, designing the bodywork for all the 30s & 50s “TD” range of track type tractors plus the interior layouts of a great number of I-H dealerships as well. Loewy also designed the bodywork for Caterpillar’s first wheel tractor, the DW10.
Some examples of late 1940s literature from Garwood, LaPlant-Choate and Allis-Chalmers. All of these brochures are packed full of interesting information and pictures. As a source of reference they are invaluable. The LaPlant-Choate motor scraper and Allis-Chalmers HD-19 were styled by Otto Kuhler.
Japanese-based Cat D5 LGP 68J series dozer pictured in some rather unfavourable muck. The D5 LGP was a development of the 90B series D6B and was very popular in Asia where underfoot conditions like this would stall a tractor with normal undercarriage. The machine is equipped with a modified 5S blade. (Photo: Authors collection
Now this is a very rare piece of machinery, an International E295B elevating scraper. Less than 100 were constructed in a period spanning 1965 to 1974. The E295B used the tractor unit of the I-H 295B mated to a bowl jointly manufactured by International and Johnson Manufacturing
Days work over, this rural Iowa, USA domiciled powershift D5 sits in the shade of a tree awaiting tomorrows work. Bridging the gap between farm and construction, the D5 was neither too big or too small for most farm-based tasks. The small “house” on top of the radiator is a lockable compartment to protect the radiator filler
Working in a mud ‘soup’, this Cat D5B LGP is a later development of the earlier D5 LGP model and was introduced in 1977. It is fitted with the non-turbocharged Cat 3306 engine. Equipment includes the (by now) standard ROPS frame and a 5S blade with a tilt cylinder.
This could be a New Zealand scene but was in fact shot in Japan. High above the valley below, this direct drive Cat D5 is cutting access tracks above a new dam site with it’s 5A angle nlade. The machine has no ROPS, just a sun canopy and the operator's steely nerve.
This photo of a prototype International 295B was taken at International’s proving grounds in Arizona, 1961. Push tractor is an International TD-25B. Eagle eyes will spot that the 295B is on narrow base tyres – not out of the ordinary but unusual as the nominal tyre was the wide base 33.5x33.
Caterpillar D5 SA (special application) agricultural tractor pulling a set of tynes through some previously tilled land in preparation for planting. Designed specifically for farm use, the D5 SA had a closely spaced manual transmission to ensure the right speed for any trailed implement. There was at least one of these imported into New Zealand, owned by the late Roger Taylor of Pokeno
The Model 295 PayScraper was International’s first real attempt at designing and building a motor scraper. 📸 International 295B getting a helping hand from a TD-30 push dozer. These units belong to Talbott Construction and were working on Interstate 64 near Lexington, Kentucky, in the mid-1960s.
For Sale! Fully optioned D5 SA pictured at a used agricultural machinery dealers yard in Idaho. This machine has all the goodies, ROPS air-conditioned cab, extended aircleaner and exhaust, and at least 3 hyrdraulic circuits to the rear. The full length fenders were a feature of the SA tractors. Just what the extra construction is mounted next to the cab the author is unsure of. The machine has been, at some time, fitted with a front counterweight but this has been torched off.
