UTB/UNIVERSAL 684 POWER
ENGINE DETAIL
The UTB/Universal 684 is a robust tractor powered by a 4-cylinder, 3.8L diesel engine, featuring a displacement of 229.4 ci, which provides a sufficient power output of 68 hp at a rated RPM of 2400. Its bore and stroke dimensions (102 x 115 mm) suggest a relatively long-stroke design, typically enhancing torque at low RPMs, making it suitable for heavy tillage tasks in agricultural settings. However, the 12-volt starter system may limit cold-weather starting performance compared to 24-volt systems, necessitating proper maintenance and battery management for optimal functionality.

UTB/UNIVERSAL 684 TIRES
The UTB/Universal 684 features a 2WD configuration, with front tires sized 11.2R24 and rear tires 16.9R30, which enhance traction and stability during agricultural operations. The larger rear tires provide better flotation in softer soil conditions, while the front tires support heavier loads and maneuverability. However, the 2WD setup may limit performance in hilly or slippery terrains compared to 4WD tractors, making it best suited for flat, well-drained agricultural fields.
