White Field Boss: one brand built from three traditions, from the 16 to the 2-110, 11.9 to 198.6 kW, three- to eight-cylinder engines with water cooling

Between 1960 and 1963, White Motor Company successively acquired Oliver, Cockshutt and Minneapolis-Moline; in 1969 the three brands were merged into White Farm Equipment. From 1974, the silver Field Boss livery completely replaced the traditional colours: Oliver green, Minneapolis-Moline yellow, and the Cockshutt models.

The register lists 18 live models, from the 16 to the 2-110, built between 1976 and 1988. Output ranges from 11.9 to 198.6 kW, weight from 499 to 13,705 kg, displacement from 852 to 10,457 cm3, across three- to eight-cylinder engines.

The enormous spread, from under 500 to over 13,700 kg, shows that the Field Boss name covered everything from compact yard tractors to large field tractors for big operations.

By unifying the range under one brand, White simultaneously ended decades of independence for Oliver, Cockshutt and Minneapolis-Moline in the US.

The enormous weight spread, from under 500 to over 13,700 kg, means practically every category of the ISO 730 three-point linkage occurs under the Field Boss name, from Category 0 on the smallest yard tractors to Category III on the largest field tractors. On a specific example, the actual category therefore matters more than the model designation alone. That spread also shows how many different markets and applications one single brand name had to serve at once.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
  • Check the weights in the papers against the figures here — attachments change them.
  • Check front and rear tyre sizes: mismatched pairs strain the drivetrain.
  • Shift the gearbox cold and warm — jumps only show up at temperature.
  • Load the hydraulics and watch for sag.
  • Ask about parts availability for this build year — the running costs hang on it.
