This was achieved by making the linkage not a simple parallelogram, but by making the length of the track rod (the moving link between the hubs) shorter than that of the axle, so that the steering arms of the hubs appeared to "toe out". As the steering moved, the wheels turned according to Ackermann, with the inner wheel turning further. [3]
A 1939 Model WC. 1942 Model WC at Jarrell Plantation A 1947 Model WC. A 1948 Model WC. The Model WC was a tractor made by Allis-Chalmers from 1933 to 1948. The WC was designed from its start as a nimble, low-cost, but well-powered row-crop tractor that would make the best use of pneumatic rubber tires, which Allis-Chalmers had just introduced to agriculture in 1932.
The engine remained the same, but turned at a higher RPM and had a higher degree or compression, yielding 11 percent more power. It was provided with a new four-speed transmission, and power assist rear wheel adjustment was introduced. The CA was produced with single and narrow dual wheel front ends, and an adjustable wide front axle. [5] [6] [4]
To compensate for the uneven (35/65) weight distribution caused by the rear-mounted engine, DeLorean used rear wheels with a diameter slightly greater than the front wheels. Before that was the rear-engined Škoda's from Škoda 1000MB (produced from 1964) to Škoda 130/135/136 (produced until 1990) or the Polski Fiat 126p (produced until ...
In the late 1970s, Ertl offered a series of plastic model kits of heavy commercial trucks, over-the-road trailers, tractors, plows, and farm wagons. Although these kits never achieved the hoped-for popularity, they led to the acquisition of AMT. In 1983, AMT was purchased by Ertl from Lesney, and renamed AMT/Ertl.
The two-wheel–drive (2WD) division was introduced in 1983.. The division imposes a weight limit of 2,800 kilograms (6,200 lb) on each competing truck, a maximum width of 2.4 meters (8 ft), and a maximum distance of 4.6 meters (15 ft) from the centerline of the rear axle to the front of the vehicle (including weight racks and tow hook).
The MKR15 recovery variant is able to flat tow a 110,000 pound (49895 kg) vehicle, is able to lift and tow a 96,000-pound (43545 kg) vehicle, is equipped with rear-mounted winches with a 78,000 pound (35380 kg) combined straight-pull rating, and a front-mounted self-recovery winch with a 20,000-pound (9072 kg) straight-pull rating.

The rear axle was driven from the engine by gear or chain-drive. These unusual locomotives were sold to small industries for use in shunting and marshalling duties, although they also found favour with engineering firms engaged in the construction of mainline railways for hauling men, equipment and materials over the partly constructed line.
