Introduction
Ursus 5312 Utility Tractor
The Ursus 5312 is a utility tractor manufactured in Warsaw, Poland, between 1993 and 2009. Designed for general agricultural tasks, it combines a standard mechanical configuration with a 70 hp diesel engine to provide a versatile platform for field work and material handling.
Engine and Performance
The tractor is powered by the Ursus 4390, a 3.9-liter, 4-cylinder liquid-cooled diesel engine. It utilizes direct injection and glow plugs for starting, delivering 70 hp (52.2 kW) at a rated speed of 2200 RPM. The engine produces 192.5 lb-ft (261.0 Nm) of torque at 1400 RPM, providing consistent power for demanding traction requirements.
Transmission and Drivetrain
The 5312 offers multiple transmission configurations to suit operational needs. The base model features 8 forward and 2 reverse gears. Optional configurations include a 12-speed setup or a 16-forward/8-reverse transmission equipped with a two-speed power shift, allowing for on-the-fly speed adjustments without clutching. All variants utilize a 305mm dry disc clutch.
Hydraulics and PTO
The hydraulic system operates at a pressure of 2321 psi (160.0 bar) with a pump flow of 6.9 gpm (26.1 lpm). The rear hitch is a Category II type with position and draft control, capable of lifting 4850 lbs (2199 kg). The rear PTO provides dual speeds of 540 and 1000 RPM, engaged at 1993 and 2000 engine RPM respectively.
Operator Environment and Dimensions
The tractor is built on a 87.4-inch (221 cm) wheelbase with a width of 79.1 inches (200 cm). It comes standard with a two-post ROPS for operator safety, though a heated cab was available as an option. Maneuverability is facilitated by power steering, while stopping power is provided by mechanical wet disc brakes.
Conclusion
The Ursus 5312 is a straightforward, robust utility tractor suitable for small to medium-sized agricultural operations. Its mechanical simplicity, combined with a variety of transmission and hitch options, makes it an adaptable machine for a wide range of implements and field conditions.
