CLAAS 257 POWER
ENGINE DETAIL
The Claas 257 features a NEF F4CE0454C turbocharged 4-cylinder engine with a displacement of 4.5 L, delivering 90 hp at 2300 RPM, which is suitable for moderate agricultural tasks. Its high torque of 270 lb-ft at 1400 RPM enhances low-end power delivery, making it ideal for heavy-duty applications such as plowing or towing. However, while the engine's design emphasizes efficiency, potential challenges could arise in power management at higher RPMs during less demanding tasks, requiring optimal gear selection for effective load handling.
