ENGINE DETAIL
The Rumely OilPull Y 30/50 features a robust 2-cylinder, kerosene-powered engine with a substantial displacement of 910.8 cubic inches, allowing for high torque output suitable for heavy-duty applications. However, its lower rated RPM of 635 may limit peak power and responsiveness compared to modern tractors, potentially impacting productivity in fast-paced farming situations. The extensive coolant capacity of 92 quarts supports prolonged operational periods, enhancing reliability during heavy fieldwork while minimizing overheating risks.

TRANSMISSION
The Rumely OilPull Y 30/50 features a simple transmission setup with 3 forward and 1 reverse gear, allowing for straightforward operational control. This limited gear selection can be advantageous for ease of use but may pose challenges in varied terrain, restricting speed adaptability and torque management. Ideal for flat fields or consistent tasks, it may struggle in rugged conditions where more gear options would enhance performance.

MECHANICAL
The Rumely OilPull Y 30/50 features a 4x2 2WD chassis, which provides a lightweight and manageable operation, ideal for farming tasks on flat terrains but may struggle on steep or muddy conditions. Its open operator station enhances visibility and operator comfort but may expose the operator to weather elements. The 3-speed transmission offers versatility in speed selection for various field applications but could limit power transfer in challenging conditions compared to modern CVT systems.
