ENGINE DETAIL
The Farmall 140 features a robust International Harvester C-123 gas engine with a displacement of 122.7 ci, providing balanced torque at a rated RPM of 1400, ideal for field applications. The oil bath air cleaner enhances engine longevity by minimizing particulates, while its low compression ratio (6.94:1) supports fuel efficiency and smoother operation under load, though it may limit power for heavy-duty tasks. Notably, the choice between a 6-volt and 12-volt starting system can impact reliability and ease of use, especially in colder climates.

FARMALL 140 ENGINE
The Farmall 140, equipped with a 2.0L 4-cylinder gasoline engine, offers a power output that balances efficiency and performance, making it suitable for small to mid-sized farming operations. Its 11-gallon fuel tank allows for extended operational hours, reducing downtime for refueling, which is advantageous during critical planting or harvesting periods. However, operators should also consider the tractor's fuel consumption rates in relation to workload, as the efficiency may vary under heavy load conditions.

| Fuel tank | 11 gal/41.6 L |
TRANSMISSION
The Farmall 140 features a sliding gear transmission, providing 4 forward and 1 reverse gear options. This setup is advantageous for versatility in various farming tasks, enabling smooth operation across different field conditions. However, operators may face challenges with gear shifting precision, especially under load, which could impact efficiency during frequent directional changes.

| Gears | 4 forward and 1 reverse |
MECHANICAL
The Farmall 140 features a 4x2 2WD chassis, providing basic maneuverability but limited traction in challenging terrains, which can be a disadvantage for hilly or muddy conditions. Its manual steering and differential contracting band brakes offer simplicity and reliability; however, they may require more operator effort and maintenance. The 4-speed sliding gear transmission allows for versatile speed adjustments, making it suitable for a range of light farming tasks, though the lack of an enclosed cab might limit operator comfort in adverse weather conditions.

FARMALL 140 TIRES
The Farmall 140 tractor's Ag front tires (5.00-15) provide excellent maneuverability in confined spaces, while the larger Ag rear tires (11.2-24) enhance traction and stability on uneven terrains, ideal for row crop applications. This configuration allows for efficient power transfer and effective soil cultivation, although the front tire size may limit load-bearing capacity compared to larger tractors. In scenarios requiring tight turns and precise navigation, such as in orchards or smaller fields, the Farmall 140 excels due to its compact dimensions and nimble handling.
| Ag front | 5.00-15 |
| Ag rear | 11.2-24 |
DIMENSIONS
| Wheelbase | 71 inches/180 cm |
| Length | 107 inches/271 cm |
| Height | 83 inches/210 cm |

| Operating weight | 3,000 lbs/1360 kg |
| Ballasted weight | 4,825 lbs/2188 kg |
DIMENSIONS & TIRES
The Farmall 140's 71-inch wheelbase offers enhanced stability for row crop applications, making it suitable for narrow spaces like orchards or small fields. Weighing 3,000 lbs, it strikes a balance between maneuverability and stability, although its lighter weight can limit traction in heavier soil conditions. The tire configuration (5.00-15 front and 11.2-24 rear) provides good flotation in soft soils but could require additional ballast for optimal performance in hillier terrains.
