STEYR will bring five tractor ranges to Interforst 2026 in Munich, Germany, with the new 435 hp Cervus CVT serving as the high-horsepower centerpiece of a display focused on professional forestry, municipal work and specialized applications.
The international forestry and forest technology exhibition runs from October 15 through October 18, 2026, and STEYR will exhibit at outdoor stand FS.1109/1. The lineup will include the Plus, Expert CVT, Profi CVT, Impuls CVT and Cervus CVT, covering everything from compact forestry and loader work to high-power PTO applications and heavy transport. Three additional tractors will work in the show’s Action Area, performing practical forestry operations.
All five ranges use FPT Stage V engines, with displacement across the display extending from 3.6 liters in the smaller machines to 8.7 liters in the flagship Cervus CVT.
Cervus CVT Targets Heavy Forestry Work
The Cervus CVT is likely to attract the most attention because it moves STEYR into a substantially higher power category than its previous conventional tractor offering.
Introduced in late 2025, the Cervus range consists of the 6360, 6390 and 6440 Cervus CVT, with maximum outputs of 360, 390 and 435 hp respectively. All three use an 8.7-liter FPT Cursor 9 six-cylinder turbocharged and intercooled diesel engine. The engine is integrated into a structural sump design intended to increase chassis rigidity while limiting vibration under heavy loads.
The tractors use STEYR’s S-Control CVT continuously variable transmission. The latest system employs a 4×2 range configuration and allows road speeds of up to 60 km/h, or about 37 mph, where regulations permit. The Cervus also carries 680 liters, approximately 180 U.S. gallons, of diesel and has a 750-hour engine service interval.
For forestry work, however, the most interesting development is not simply the 435 hp output.
STEYR will use Interforst to demonstrate the Cervus platform’s potential for applications such as wood chipping, where substantial continuous PTO power can be more important than drawbar performance. A forestry cab demonstrator will show a future reverse-drive capability that would allow the operator to work facing equipment mounted behind the tractor.
That configuration could significantly change the practical role of the Cervus. A conventional high-horsepower agricultural tractor can already power a large chipper, mulcher or other forestry implement, but prolonged operation while facing rear-mounted equipment creates compromises in visibility and operator ergonomics. A properly integrated reverse-drive station would make the tractor much more competitive as a dedicated implement carrier rather than simply an agricultural tractor adapted for occasional forestry work.
Impuls CVT Expands Forestry Range
The Impuls CVT provides a smaller and more versatile alternative for contractors that do not require Cervus-level power.
Current Impuls models use a 6.7-liter six-cylinder FPT engine, with maximum output reaching 225 hp. Depending on configuration, the range combines the engine with STEYR’s S-Control CVT or S-Control 8 transmission. The CVT version can reach 50 km/h at low engine speed, while hydraulic capacity and hitch specifications make the platform suitable for demanding mounted and hydraulically driven equipment.
STEYR lists rear lift capacity at more than 8,000 kg on current Impuls configurations, while the forestry specification is aimed at jobs including timber handling, transport, vegetation management and work with forestry attachments.
The importance of the Impuls in this lineup is its position between specialized compact machines and the much larger Cervus. Forestry contractors frequently need one tractor to perform several completely different jobs during the year, making power density, hydraulic capability, transport speed and attachment compatibility more important than maximum horsepower alone.
Plus Adds Compact Forestry Option
At the lower end of the display, the STEYR Plus illustrates how the same forestry strategy is being applied to smaller tractors.
The Plus range uses a 3.6-liter four-cylinder FPT Stage V engine and covers approximately 80 to 117 hp. Available equipment includes the S-Control 2 24×24 transmission, Powershuttle, an 82 L/min hydraulic pump and rear lift capacity of up to 4,700 kg.
STEYR introduced a dedicated forestry specification for the Plus earlier in 2026. The package places greater emphasis on machine protection, maneuverability and compatibility with front and rear forestry equipment, addressing operations where the physical size of a tractor can matter as much as engine output.
This gives STEYR a notably broad forestry spread. Instead of attempting to make one tractor architecture cover every job, the company can offer compact Plus machines for confined terrain, mid-range Expert and Profi platforms, Impuls tractors for higher-output mixed work and the Cervus for the heaviest PTO and power-intensive applications.
AI Camera Detects People and Vehicles
Another Interforst exhibit will shift attention from horsepower to machine awareness.
STEYR plans to show a municipal-specification tractor fitted with an AI-assisted camera system from MekraLang. The system uses vehicle and pedestrian detection to identify objects around the tractor and then marks them visually on the operator display.
This type of technology is particularly relevant to forestry and municipal machinery because attachments, cranes, trailers and the tractor structure itself can create substantial blind zones. Operators may also work close to ground crews, trucks and other machinery.
The important distinction is that the system supports the driver rather than replacing the driver. Its practical value comes from directing attention toward detected hazards that may otherwise be difficult to see, especially during reversing, attachment operation or maneuvering in restricted areas.
Combining camera-based object detection with existing tractor electronics also points toward a broader development path. Forestry machines are gaining many of the same sensing and assistance technologies already appearing in construction and agricultural equipment, but their operating environment is often more complex because vegetation, uneven terrain, people and machinery may all occupy a relatively small working area.
Forestry Demonstrations at Interforst
STEYR will place three tractors in the Interforst Action Area rather than limiting the display to static machines.
That matters for forestry equipment because specifications reveal only part of machine performance. Visibility, low-speed control, maneuverability, attachment integration and operator positioning are difficult to assess from horsepower and hydraulic figures alone.
The five STEYR ranges on display will use FPT Stage V engines spanning 3.6 to 8.7 liters, illustrating how the CNH brand is attempting to build a forestry offering around existing tractor platforms while adding application-specific protection, controls and equipment.
The Cervus reverse-drive demonstrator may ultimately be the most significant part of the exhibition. If the production version provides a fully integrated driving position rather than a limited seat-and-control conversion, it could open a much larger market for the platform among contractors operating high-capacity chippers, mulchers and other rear-mounted forestry equipment.
Wald Klima-Klasse Expands in 2026
The machinery display will be accompanied by the next phase of the Wald Klima-Klasse initiative involving STEYR, the German Forest Owners Association AGDW and FPT.
During 2025, 75 students from three German schools participating in the program planted 1,800 trees. The 2026 phase is intended to move beyond individual planting events toward longer-term implementation and broader adoption across Germany.
Representatives from AGDW and its Initiative Group of Forestry Cooperatives will attend Interforst to discuss biodiversity, forest management and environmental education. Students from FOS Lindau and Realschule Lindenberg who have already participated in project activities are also expected to visit the exhibition.
What the Interforst Display Means for STEYR
The Interforst lineup shows a more deliberate forestry strategy than simply offering agricultural tractors with additional guards.
At one end, STEYR is adapting relatively compact tractors such as the Plus for maneuverability and protected forestry operation. At the other, the 435 hp Cervus gives the company enough engine and PTO capacity to target jobs traditionally handled by highly specialized high-power machines.
The proposed reverse-drive system is particularly important. Horsepower alone does not make an agricultural tractor an effective forestry carrier. Operator orientation, protection, cooling capacity, low-speed control, hydraulics and attachment integration ultimately determine whether the machine can work efficiently for entire shifts.
If those elements are developed alongside the new Cervus platform, STEYR could use its existing tractor architecture to address specialized forestry applications without developing an entirely separate forestry prime mover. That approach could also benefit contractors who need the same machine for chipping, transport and conventional agricultural work during different parts of the year.
