Engine

Powerful with low consumption

FORTERRA tractors boast four-cylinder ZETOR engines with a power of 96 hp to 147 hp. Their unique construction means they represent an alternative to competitive six-cylinder tractors. ZETOR engines are reliable, powerful and excel in low consumption. The simple construction of the engine with minimum electronic elements guarantees low operating costs, long life and easy maintenance.

The economical ZETOR engines with 16-valve cylinder heads are the result of Zetor’s own development and manufacture. The engine construction is tailored to the requirements of a specific model, which is a guarantee of long service life, optimum performance and low fuel consumption.

Low consumption leader

The new ZETOR engines in the Stage V emission standard offer a significant consumption and emission reduction. They are based on Stage IV compliant engines and thus retain the operational and economic parameters of the previous generation.

These aggregates were tested by researchers from Mendel University and the results of the study confirmed that they have up to 19.2 % lower consumption than the engines in the Stage IIIB standard.

The use of the new Eco 40 gearbox additionally reduced fuel consumption.

Gearbox

Matching force and accuracy

The four-speed, fully synchronized FORTERRA CL gearbox has two speed ranges and an automatic three-stage multiplier (24/18). The FORTERRA HSX and FORTERRA HD are equipped with an innovated 40ECO gearbox with 30/30 speeds, tree-stage automatic multiplier (PowerShift) and hydraulic reverser (PowerShuttle).

ZETOR uses in-house development and manufacturing facilities for the FORTERRA gearboxes.

A higher number of usable speed gears keeps the engine at the optimum speed when working in the field, as well as during transport. This keeps the fuel consumption low. In the most frequently used working range of 4–12 km/h, you can rely on up to 13 gear speeds. The more comfortable gear shifting and easier operation of FORTERRA tractors are also enabled by the function of the automatic torque multiplier which that ensures automatic gear shifting of the multiplier depending on the engine speed.

Since 2018, the FORTERRA HSX and FORTERRA HD have been equipped with the innovated ECO40 gearbox. The new gearbox allows users to reach the maximum speed (40 km/h) at lower revolutions (1800 rpm). This optimization leads to fuel savings of up to 18%, and reduces the noise and wear of the engine.

HYDRAULICS

Force and efficiency

Standard ZETOR FORTERRA versions are equipped with electro-hydraulic three-point hitch control ensuring high efficiency when working with coupled implements. To make working in the field easier and of a higher quality, the Forterra HD machine is equipped with an automatic headland turning sequence system.

Maximum lifting force
Forterra CL 77 kN
Forterra HSX & Forterra HD 85 kN

Forterra HD is equipped with an additional four hydraulic quick couplers with electro-hydraulic control.

Axle

Comfortable driving

The Forterra HD (standard) and Forterra HSX (optionally) are equipped with independent suspension of the front axle, which is structurally comprised of two separate and independently suspended half-axles. Thanks to smaller sprung masses, the axle has higher absorption and damping capacities and, therefore, a lower vibration level is achieved.

The mechanism of the independent wheel suspension is technically very similar to multilink car wheel suspension; therefore the drive in the Forterra HD and Forterra HSX tractors is as comfortable as in a car.
