Zetor Forterra: the powerful four-cylinder since 1998, from the 95 to the FORTERRA 140 HSX, 59.6 to 108 kW, four- and six-cylinder engines with water cooling
Forterra, a name combining "for" and "terra" (terrain), first left the Brno plant in late 1998, built on the Unified Row III platform whose first prototypes date back to 1974. In 2012 the Forterra HSX arrived with an electro-hydraulic power shuttle, followed in 2014 by the Forterra HD rated up to 110 kW.

The register lists 19 live models in this series, from the 95 up to the FORTERRA 140 HSX, with outputs from 59.6 to 108 kW, weights from 4,075 to 6,350 kg, and displacements between 4,150 and 6,001 cm3 across four- and six-cylinder engines.
Zetor positioned the Forterra as a rugged mid-range tractor for field, forestry and municipal work, technically simpler than its flagship models but noticeably stronger than the Proxima line. By its 20th anniversary, Zetor counted around 21,500 Forterra tractors sold across 55 countries.
When buying used, the build year matters: early Forterra models from the late 1990s differ substantially from the later HSX and HD versions with their more modern hydraulics and power shuttle transmission.
Zetor, as a Czech tractor maker, remains an independent, active company today, which eases spares supply for the Forterra line through the regular dealer network, unlike many of the long-discontinued brands otherwise gathered on pages like this one. In the power class of 59.6 to 108 kW, the ISO 730 three-point linkage is mostly built to Category II, with the PTO usually offering both standard speeds, 540 and 1,000 rpm.

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.
