The self-leveling combine Claas harvester Trion 540 Montana 4 ensures quality, speed, and operational safety during harvesting activities carried out on terrain characterized by extreme slopes.
It can handle side inclinations of up to 38 percent, uphill gradients of 32 percent, and downhill slopes of 11 percent
The slogan “no limits” first appeared in the early 1990s thanks to the insight of a watchmaking brand that used it to associate its product line with the world of extreme sports, riding the wave of what marketing professionals of the time called the “massification of the concept of adventure.”
Quickly becoming a true trademark, the slogan later evolved into a leitmotif evoking the abilities that allow a person or a product to face and overcome the most difficult challenges and trials. In that specific case, the fact that the watch accompanied the extreme performances of the brand’s chosen ambassadors became proof of efficiency, durability, and precision—qualities that remained intact even under conditions far beyond the ordinary.
This kind of functional “extraordinariness,” when applied to agricultural mechanization, perfectly describes the mission profile of the self-leveling combine harvester “Trion 540 Montana 4” by Claas. The machine was specifically developed by the German brand’s engineers to support harvesting operations on hilly terrain with steep gradients—conditions that effectively prevent the use of any other machine of this type.
The electronic management of the leveling system not only allows the machine to handle side slopes of 38 percent, uphill gradients of 32 percent, and downhill slopes of 11 percent even under full load, but also ensures safe maneuvering.
This is achieved through refined engineering of all components that make up the three core parts of the system: the frame, the front axle, and the rear axle. The frame is made of high-strength steel and can withstand loads of up to 25 tons, while the front and rear leveling cylinders feature large supports and rods operating at low pressure to minimize stress on the hydraulic system. The rear axle also includes a two-part stabilizer bar to improve reliability.
In essence, this is a machine designed to handle unconventional operating conditions. This is further supported by the presence of a feeder channel incorporating a dedicated coupling ring with heavy-duty supports, allowing the header wide oscillation and maintaining the desired working position regardless of crop conditions.
The crop is processed by Claas’s proven primary separation system “APS,” structured around three units: an accelerator, a threshing drum, and a beater, enabling up to 20 percent more grain separation compared to traditional systems.
The crop flow is first straightened by the accelerator before reaching the threshing drum—a 600 mm diameter cylinder equipped with eight rasp bars and paired with an electro-hydraulically adjustable concave controlled from the cab. This operates with a wrap angle of 142 degrees and a separation area of just under 1.3 square meters.
Through a transfer rotor (the third APS component), the material is then conveyed to five straw walkers, each nearly 4.5 meters long, providing a secondary separation area of 6.5 square meters. The separation process is further enhanced by the standard “MSS” (Multi Finger Separation System), a guided-finger cylinder that intensively aerates the material, ensuring more effective crop flow and improved straw treatment.
Final grain cleaning is handled by the “Jet Stream” system, featuring turbine fans, hydraulic fan speed control, and a pre-cleaning stage with dual airflow. The upper and lower sieves provide a total cleaning area of over five square meters. Thanks to the “3D” system, full cleaning performance is maintained even on lateral slopes of up to 20 percent, while the “AutoSlope” system automatically adjusts fan speed when operating uphill or downhill.
The harvested grain, monitored for losses to optimize performance, is stored in an 8,000-liter grain tank, which can be unloaded at a rate of 110 liters per second via an unloading auger capable of rotating 105 degrees. It can also be equipped with a “Profi Cam” camera to give the operator a direct wide-angle view of the trailer during unloading.
If straw is not to be windrowed, it is managed by the “Special Cut” chopper with 72 blades and adjustable deflectors, allowing the operator to set spreading width and direction. These parameters are stored and automatically maintained even in crosswinds or on slopes.
Reduced Energy Consumption
Like the flatland version “Trion 540,” the Claas “Trion 540 Montana 4” is powered by a Cummins “L9 Harvest” six-cylinder engine with a displacement of 8.9 liters, delivering up to 354 horsepower. Equipped with a variable geometry turbocharger and Cummins “XPI” common rail system, the engine achieves peak torque at 1,900 rpm during fieldwork and 1,650 rpm during road transport—values that help minimize energy consumption.
Further efficiency is ensured by the “Dynamic Power” system, which continuously optimizes the relationship between delivered performance and power demand, adjusting engine output curves accordingly. This allows the machine to operate at maximum efficiency while reducing fuel consumption by up to 10 percent compared to engines without this mapping.
The engine complies with Stage V emissions standards through SCR systems combined with DOC catalysts and DPF filters, eliminating the need for EGR systems. It is paired with a two-speed hydrostatic transmission (field and road) and an electro-hydraulic rear-wheel drive system designed by Claas. This system uses a central hydraulic motor to drive the rear wheels via a differential and is electronically controlled to manage wheel slip through dedicated sensors and valves.
Everything Automatic
To maximize harvesting efficiency, the “Trion 540 Montana 4” also allows operators to delegate separation system management to the “CEMOS” system, an onboard software suite that optimizes machine settings through two modes. “CEMOS Dialog” improves settings progressively through interaction between the operator and the machine, while “CEMOS Automatic” intelligently adjusts parameters based on changing harvesting conditions.
Functions such as “Auto Header” and “Cruise Pilot” manage the Vario cutting platform and forward speed, respectively. Additional systems—“Auto Threshing,” “Auto Separation,” “Auto Cleaning,” “Auto Crop Flow,” and “Auto Slope”—automatically adjust threshing, residual grain separation, cleaning, crop flow, and fan airflow.
As a result, operators can focus solely on driving, although even this can be automated via three different steering assistance systems. All machine parameters can also be monitored in real time by farm technical offices through the “Claas Connect” telemetry system.
The cab of the “Trion 540 Montana 4” is a highly connected, high-visibility environment with spacious interiors and features designed to minimize operator fatigue during long and demanding work cycles. These include full climate control, air-suspended leather seats that rotate up to 30 degrees on both sides, a 30-liter refrigerated compartment for food and beverages, 360-degree windshield wipers, and LED work lights ensuring full visibility in all conditions.
