Fuel Economy & Reduced Parasitic DragEliminates continuous fan drag under moderate engine temperatures, freeing engine horsepower, lowering fuel consumption, and reducing fan noise.

Heavy-Duty ArchitectureEngineered with reinforced bearings and high-grade seals built to endure harsh agricultural environments, severe vibration, and fine field dust.

Exact Direct OEM FitmentManufactured strictly to original John Deere RE274876 pilot dimensions, bolt patterns, and dynamic balance specifications for straightforward installation.
