New Holland – other models: the collective page of big tractors outside the named ranges, from the Genesis 8670A to 8970 through the articulated TJ275 to TJ450 to the TV6070 Bi-Directional, 67 to 340 kW
This page gathers the New Holland tractors the register could not assign to a named range – big tractors only: the Genesis range (8670A, 8770, 8870, 8970), the articulated TJ models (TJ275 to TJ450) and the TV6070 Bi-Directional, whose operator station can turn for work with rear-mounted implements. The Genesis range emerged in the 1990s under Ford New Holland as a big-tractor programme with its own purpose-built Genesis engine; the TJ range took over the engineering of the articulated Versatile tractors from Winnipeg after Ford New Holland acquired their plant. New Holland itself traces back to a farm-machinery works founded in Pennsylvania in 1895 and has belonged to CNH since the Fiat-Case merger of 1999.

The register lists here 14 versions with 67 to 340 kW (90 to 450 hp), all six-cylinders of 7,480 to 14,945 cm³, unladen weights from 4,802 to 17,917 kg, lengths from 4,397 to 7,558 mm and widths from 2,180 to 3,683 mm; engines come from Ford, New Holland, CDC, Genesis, Cummins and FPT.
The Genesis and TJ big tractors of the 1990s and 2000s addressed large North American operations and eastern European and Russian agribusinesses with very large fields; the TV6070 Bi-Directional served a niche of farms needing a tractor for both front and rear work with full sight of the implement.
On used examples of the Genesis and TJ models, operating hours, the condition of the articulation joint and four-wheel steering, hydraulic output and cab electronics count, on the Bi-Directional also the function of the rotating control console; parts run through the CNH network, though with these small production numbers they are sometimes only available second-hand or through specialist dealers.
