CLAAS presents first battery-electric wheel loader at Agritechnica 2025

With the TORION 537e SINUS, CLAAS is presenting its first battery-electric wheel loader at Agritechnica 2025. The machine, which is in the six-tonne class, combines the unique advantages of the SINUS series with a low-noise and locally emission-free electric drive, but offers the full performance of a comparable model with a conventional drive. These features make the TORION 537e SINUS particularly suitable for use in livestock farming, where a quiet and emission-free environment significantly increases animal welfare and productivity. Operators also benefit from the low noise emissions and locally emission-free technology - as well as easy maintenance of the drives.

Long running time, short loader: Lithium-ion battery with onboard charger
In the TORION 537e SINUS, a battery-electric drive replaces the diesel engine and hydrostat of the otherwise identical TORION 537 SINUS. The lithium-ion battery with modular battery concept has a capacity of 32.2 kWh as standard and 64.4 kWh as an option at an average voltage of 322 V. During operation, this provides up to 30 kW for the ground drive and 15 kW for the hydraulic pump drive. In normal use, this enables running times of 8 to 16 hours, depending on the integrated battery capacity. When braking via the ground drive and when travelling downhill, the energy released is recovered by means of recuperation and fed back into the battery.

Depending on the on-board charger and available connected load, the battery is fully charged in just one and a half to three hours. The integrated on-board charging system also enables fast charging without an additional external device - for maximum charging flexibility and easy intermediate charging. The interface to the charger is easily accessible under a flap in the step-up area of the TORION 537e SINUS.

Uncompromised handling performance
When it comes to performance parameters like breakout force and cycle times, the TORION 537e SINUS is just as uncompromising as its combustion engine-powered twin, the TORION 537 SINUS. With an operating weight of 5,910 kg, the Z-bar linkage delivers a breakout force of 48 kN. And thanks to the hydraulic pump with a flow rate of 75 l/min at 240 bar, this agile loader completes the lifting, dumping, and lowering cycles in 4.9 seconds, 1.7 seconds, and 3.5 seconds, respectively – cycle times that blend seamlessly into the loading cycle thanks to the superbly tuned working hydraulics.

The standard, unique SMART LOADING assistance system supports the operator with repetitive loading tasks. It precisely coordinates all functions that contribute to optimizing loading cycles. This includes lift height and lowering depth programming, as well as automatic bucket return for accelerated and precise loading cycles.

The impressive loading performance is also due to the electric drive system with instant power delivery, rapid acceleration, and top speeds of 20 km/h as standard, and 30 km/h as an option.




Agility and stability thanks to SINUS steering
The maximum height of the bucket pivot point with the boom fully extended is 3,215 mm.

When working in confined spaces such as halls, barns, and yards, the TORION 537e SINUS benefits from its unique SINUS steering system. The combination of articulated steering with a 30-degree articulation angle and a rear axle steering system with a maximum steering angle of 25 degrees results in a minimum turning radius of just 3,520 mm (outer edge of tire). This steering concept also improves stability and leads to a very favorable ratio of operating weight to tipping load (3,750 kg fully articulated and steered).

Quiet, comfortable, and easy to navigate
Thanks to its electric drive, the TORION 537e SINUS operates noticeably quieter than its combustion engine counterpart. At just 65 dB(A) inside the cab, the wheel loader is not only pleasant to operate for the driver, but the reduced noise emissions are also noticeable outside the cab.

The spacious, ergonomic comfort cab offers optimal working conditions thanks to its ergonomic workstation and ample headroom and legroom. The generous windows provide excellent all-around visibility. The height-adjustable terminal with a touchscreen display, located to the right of the driver, allows for a quick overview of all machine and process-related data. While the lithium-ion battery is charging, the terminal displays the percentage of charge remaining and a charging time estimate, enabling optimal work planning.

Machine and process management in CLAAS connect
Using an existing or new CLAAS connect ID, users of the TORION 537e SINUS have mobile access to the machine's location and parameters. Furthermore, the maintenance history is documented in CLAAS connect, and service work can be planned proactively and efficiently in collaboration with the responsible CLAAS service and sales partner. The integrated digital operating manual, the lubricant guide for suitable oils and greases, and access to the CLAAS Parts Shop with guaranteed correct wear and spare parts save time and thus simplify machine management and daily operations.
