ENGINE DETAIL
The Advance-Rumely OilPull G 20/40 features a robust 2-cylinder, horizontally opposed engine designed for efficient kerosene combustion, offering excellent torque at low RPM (450). Its substantial displacement of 1005.3 ci allows for high power output, making it well-suited for heavy agricultural tasks. However, note the cooler capacity of 70 quarts, as maintaining optimal operating temperature is crucial to prevent overheating in extended use scenarios.

TRANSMISSION
The Advance-Rumely OilPull G 20/40 features a simple two-gear forward system and a single reverse gear, making it straightforward to operate but limiting its speed and versatility in varied terrains. Its gear type, likely a spur or helical design, may offer reliability, though it may not provide the same smoothness as a more advanced transmission. In scenarios requiring rapid speed changes or complex maneuvers, the limited gear selection may pose a challenge for efficiency in tasks such as plowing or hauling heavy loads.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The Advance-Rumely OilPull G 20/40 features a 4x2, 2WD chassis, which offers simplicity and ease of maintenance but may struggle with traction on uneven terrain. Its canopy over an open platform design provides operator protection while maximizing visibility, a balance useful for field operations. The 2-speed gear transmission allows for versatility in speed adjustments; however, the limited gear range may restrict performance in varied workloads.
