Steiger Wildcat ST-210 – Tiger ST-470 Series III

The Series III Steigers were the most successful in the brand's history. At this stage, the market share of four-wheel-drive tractor sales in the USA was 36%. The Series III tractors were larger and heavier than before. Both Cummins and Caterpillar engines were used, and in many cases, the same model was available with either option. Not all options are presented here. The torque characteristics of the engines had significantly improved at this stage. Torque increases ranged from 25 to 38%, depending on the model, except for the Panther ST-350, which was noticeably less powerful. The transmission was a Dana-Spicer 10-speed, which in most cases also included a reduction gear. Hydraulic pump outputs had risen to around 110 liters per minute, and four hydraulic valves were standard. The cab was the new Safari Cab. Air conditioning was standard, and noise levels were about 80 decibels. A front axle lock was available as an optional extra. The axles for most models were made by Steiger’s licensed manufacturer Raba in Hungary. In the early years, the Wildcat III, the smallest of the Series III, was in many ways a continuation of the old design and corresponded with minor changes to the Wildcat II.
In 1977, the model range was complemented by the Tiger III. It was available with either a 450-horsepower Caterpillar or a 470-horsepower Cummins engine. The transmission was a 6-speed Allison full powershift.
