The White Farm Equipment, which had passed to new owners, continued under the WFE brand, but financial difficulties persisted still in 1983, when the articulated models 4-225 and 4-270 were introduced. The factory was shut down for most of the year, and these models only entered production towards the end of the year. The 4-225 Field Boss was a direct development of its predecessor, the 4-210. The 10.4-liter Caterpillar engine had received a turbocharger, and the power had increased to 225 horsepower. The transmission had 18+6 gears with a three-speed range gearbox. A PTO at 1000 rpm, a hydraulic lift, and dual wheels were standard equipment. The cab was significantly improved, and the noise level dropped to 78 decibels.

The 4-270 Field Boss, on the other hand, was an entirely new model and in many ways more robust. Its engine was a turbocharged 6-cylinder 10.45-liter Caterpillar. The transmission offered 16+4 gears with a four-speed range gearbox. The hydraulic lift was an optional extra. A model 4-325 was also under development, but it never reached mass production.

These models remained the last articulated tractors produced by White.
