DUTRA UB-28 POWER
ENGINE DETAIL
The Dutra UB-28 tractor, powered by a Csepel DT-213 diesel engine, features a 2-cylinder configuration with a displacement of 2.7 L, providing a modest output of 28 hp at 1650 RPM. Its high compression ratio of 21:1 enhances fuel efficiency and torque at lower RPMs, making it suitable for heavy-duty tasks such as plowing or hauling in rugged terrains. However, the limited power may restrict its use in applications requiring more horsepower, necessitating careful selection based on operational needs.

TRANSMISSION
The Dutra UB-28 features a [-|-] gear system with a total of 6 forward and 2 reverse gears, enabling efficient handling and versatility in various agricultural tasks. The six forward gears provide a balance of speed and torque, which is advantageous for diverse terrains and operational requirements. However, the limited 2 reverse gears may present challenges in tight maneuvering situations compared to tractors with more reverse options.

MECHANICAL
The Dutra UB-28 tractor features a 4x2 2WD chassis, providing adequate traction for light to medium agricultural tasks; however, its limited drive configuration may pose challenges on uneven or slippery terrains. The open operator station enhances visibility and ventilation but may lack protection from weather conditions, impacting operator comfort during extensive use. Its 6-speed gear transmission offers flexibility in speed management, making it suitable for various farming operations, though it may require skilled operation to optimize performance.
