White’s first articulated-frame tractor, the 4-150 Field Boss, was placed in the same power class as the earlier Minneapolis-Moline A4T, but much had been redesigned using the same parts as White’s new 2-wheel drive tractors; for example, the rear end was the same as in the 2-105. The tractor’s structure was low, and the weight distribution was designed to be 50/50 when pulling an implement. The model introduced in 1974 featured a 10.4-liter Caterpillar V8 (engine power 175 hp) and an Oliver 6+2 transmission, which optionally included a 3-speed high/low range. The hydraulics used the same 75-liter variable displacement pump as White’s 2-wheel drive tractors. Likewise, the optional three-point hitch had a lifting capacity of 2700 kilograms, matching those models. The power take-off (PTO) was standard (1000 rpm with a hydraulic clutch). The cab looked the same as in previous models, and the noise level was around 80 decibels.

A year later, the 4-180 was introduced, which had more engine power, planetary gear drives in the axles, a 12+4 transmission, a dual-disc clutch, and standard 38" wheels.

In 1979, the redesigned models 4-175 and 4-210 were released. The smaller model received only minor updates, with the model designation switching from gross power (VOA) to engine power. The cab was modernized and the control levers were grouped on a console on the right side. In the larger 4-210, the powertrain borrowed from the 2-wheel drive tractors was adopted, along with an 18+6 transmission. The articulated frame was made stronger than before.
