Info
In 1975, JD’s frame-steered large tractors moved to the 30 series. At that time, the 8430 and 8630 models were introduced, with SAE engine power of 215 and 275 horsepower, respectively. The cab was a new rounded Sound Gard design, with a noise level of 80-82 dB. The engines were turbocharged and intercooled, with displacements of 7.6 and 10.1 liters. Torque characteristics were said to have been significantly improved compared to previous models. There were now 16+8 gears, and the quick shift was two-speed, as in the earlier models. The clutch was an oil-immersed Perma Clutch.
