"The Series 6 will become ZETOR's new flagship and sets a new direction for the development and assembly of our future products. With a power range from 131 to 171 HP, the Series 6 will replace the current FORTERRA model. I can already confirm that work and testing are underway for the Series 5, which will correspond in performance to the PROXIMA model range. As part of our long-term product plans, we will also introduce tractors corresponding to the MAJOR range, as well as a completely new model with over 200 HP," explains Róbert Harman, CEO of ZETOR TRACTORS a.s.

With the introduction of the Series 6, ZETOR returns to its roots when tractors were categorized by numerical series. Chronologically arranged numerical model series linked to engine performance ensure a clear categorization system, making it easier for farmers to identify the most suitable machine for their needs.

The Series 6 tractors will be equipped with four-cylinder Deutz 4.1 engines delivering a maximum power of 171 HP at 1900 rpm. With a displacement of 4.1 liters, the engines meet the Stage V emission standard through SCR, DPF, and external exhaust gas recirculation systems. The engines feature Common Rail injection, a single turbocharger, and the option to set constant speeds at two levels.

New Transmission

The new ZF TPT 16 POWERSHIFT transmission allows for smooth gear changes under load. To the basic five forward and three reverse gears, it adds a six-step multiplier for forward movement and a three-step multiplier for reverse. Including creeper gears, there will be a total of 54 forward and 27 reverse gears, with a maximum speed of 40 km/h. Main gear changes are manual via a gear lever, while the multiplier and reverser are controlled electrohydraulically. The more robust construction of the transmission also increases the rear axle load capacity to 8.5 tons, and the total tractor weight will reach 11.5 tons.

The system also includes Smart Braking, which allows the tractor to start and stop simply by pressing the brake pedal. This system is especially effective for work with a front loader.

Hydraulics and Cabin

The Series 6 features a high-performance hydraulic system with an axial-piston pump delivering a flow rate of 120 l/min. Thanks to this, the rear three-point hitch can handle a load of up to 7.2 tons, and the front hitch supports 3.5 tons. The tractor will come standard with four mechanically controlled rear hydraulic circuits and, if needed, two additional front circuits. A newly enhanced power take-off (PTO) offers selectable speeds of 540, 540E, 1000, and 1000E rpm, with an electrohydraulic clutch enabling adjustments based on the load.

The tractor cabin introduces a series of innovations. Its suspension is ensured by hydraulic dampers and coil springs. Adding to this is the tractor's suspended front axle, providing operators with maximum comfort, further enhanced by air conditioning, a radio, tiltable rear side windows for ventilation, and other features. The central column is adjustable in two directions, and the cabin includes a new armrest with ergonomically arranged controls and a 24" touchscreen monitor for tractor settings and function management. A pressurized cabin design minimizes dust and aerosol penetration, making the tractor suitable for work with sprayers.

First Practical Experiences

The Series 6 underwent intensive testing last year (2024). Several prototypes accumulated more than 1,000 operating hours under varying conditions in the Czech Republic and Germany. "We’ve been testing it since summer, and I must say it’s a significant step forward," says Tomáš Srnec, one of the test farmers in the Czech Republic. "It’s a modern machine capable of handling even the most demanding tasks, whether it’s discing, subsoiling, or transporting crops. Fuel consumption is low – for example, during shallow cultivation, we achieved only 7.5 l/ha, which is an excellent result."

The new model is designed to withstand extreme weather conditions, from summer heat to winter frost. The sale and serial production of the new Series 6 are scheduled for 2025. This modern tractor promises quality performance and customer satisfaction worldwide.
