ENGINE DETAIL
The Ursus 4512 features a robust 4-cylinder diesel engine with a displacement of 3.9L, providing 66hp at 2000 RPM and a notable torque of 180.7 lb-ft at 1400 RPM, suitable for low-speed applications such as plowing and transporting heavy loads. Its direct injection fuel system enhances efficiency, while the oil bath air cleaner reduces maintenance frequency, although it may not be as effective in extremely dusty environments. The relatively high compression ratio of 16:1 boosts power output but may also require careful management of fuel quality to prevent knocking, making it ideal for users in regions with consistent fuel quality.

URSUS 4512 TIRES
The Ursus 4512 tractor's standard tires—7.5-16 at the front and 16.9R30 at the rear—are designed for optimal traction in agricultural applications, providing good stability and load capacity. However, the relatively narrow front tire may limit steering response in soft, uneven terrain, and the rear tire's larger diameter can impact maneuverability in tight spaces. This tire configuration is advantageous for field work, but may require additional consideration when navigating narrower rows or corners.
