This page gathers the White tractors the register could not assign to a named range – from big Field Boss types of the 1970s and 1980s to small American compacts. White Farm Equipment was formed in 1969 when the White Motor Corporation of Cleveland combined the tractor divisions of Oliver, Minneapolis-Moline and Cockshutt and continued production at the former Oliver plant in Charles City, Iowa; since 1993 the brand rights have belonged to AGCO. In the Field Boss range the first digit before the hyphen gives the drive type – 2 for two-wheel-drive types such as the 2-70, 4 for the four-wheel-drive articulated tractors such as the 4-210 and 4-270 – and the following number the power class; Workhorse and Fieldmaster are separate ranges, and under the name American White sold Iseki-built compact tractors, while the GT-1650 Yard Boss is a lawn tractor. The engines come from Cummins, Caterpillar, Perkins, Isuzu and Iseki as well as White's own White-Hercules production.

The register lists here 53 versions with 3.7 to 198.6 kW from three- to eight-cylinders of 2,592 to 10,457 cm³, unladen weights from 3,525 to 13,705 kg, lift capacities from 1,406 to 7,257 kg and lengths from 2,953 to 6,502 mm.

In the 1970s and 1980s White was one of the big US tractor brands, though it stayed in the shadow of John Deere and Case; the Field Boss articulated tractors competed with Steiger and Versatile for the prairie farms, while the American compacts served the entry segment against Kubota.

On used tractors, engine condition, clutch and hydraulics count on the Field Boss and Workhorse types, articulation and four-wheel drive on the big articulated tractors, rust and the availability of Iseki parts on the American compacts; parts supply today runs through independent farm-equipment dealers and AGCO, as White no longer exists as an independent brand.

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.
  • 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.
