ENGINES OVERVIEW
The Farmall 350 tractor, equipped with a Continental 3.2L diesel engine, offers higher torque output and fuel efficiency compared to the International Harvester 2.9L gasoline and LP gas variants. Diesel engines typically deliver better longevity and lower operating costs but may have challenges with cold starting and increased maintenance. Operators should consider the intended application; diesel is favorable for heavy-duty tasks, while gasoline or LP options may suit lighter, more versatile farming operations.

ENGINE DETAIL 1
The Farmall 350 tractor features a Continental D193 diesel engine with a displacement of 3.2 liters, offering a compression ratio of 16.87:1 for efficient combustion. Its oil bath air cleaner enhances engine longevity by reducing particulate intake, while a rated RPM of 1750 provides optimal power for various farming tasks. However, the relatively low coolant capacity of 17.25 quarts may necessitate more frequent monitoring in hot conditions, particularly during extended operational periods.

ENGINE DETAIL 2
The Farmall 350 tractor features a C175 gasoline engine with a relatively low compression ratio of 7.0:1, suitable for moderate power output and efficiency at a rated RPM of 1750, ideal for agricultural operations. With a displacement of 175 cubic inches (2.9L), it provides adequate torque for plowing and cultivating tasks, but may face challenges in heavy-duty applications due to limited power compared to modern tractors. Additionally, the 6-volt starter system may pose reliability issues in cold conditions, making it important to ensure proper maintenance and battery health for optimal performance.

ENGINE DETAIL 3
The Farmall 350, powered by a 175ci (2.9L) International Harvester C175 LP gas engine, delivers a balanced output at a rated RPM of 2000, making it suitable for moderate-duty farm tasks which benefits from its liquid-cooled design that improves efficiency. The 9.0:1 compression ratio enhances fuel efficiency while the 6-volt starter system may present challenges for cold starts compared to modern systems. With a coolant capacity of 19 quarts (18.0L), the tractor can maintain optimal operating temperatures but requires regular checks to prevent overheating during prolonged use.

FARMALL 350 ENGINES
The Farmall 350 is available with multiple engine configurations: a Continental 3.2L 4-cylinder diesel and International Harvester's 2.9L 4-cylinder options for gasoline and LP gas. Key considerations include fuel tank capacities, with diesel at 18 gallons providing slightly more range than the gasoline and LP gas options at 17 and 18.4 gallons respectively. Each fuel type presents unique advantages: diesel offers better torque for heavy loads, while gasoline and LP are easier to start in cold weather, making selection dependent on operational needs.

TRANSMISSIONS OVERVIEW
The Farmall 350 features a versatile 5-speed sliding gear transmission, allowing for simpler operation and reliable performance across various farming conditions. However, the 10-speed two-speed power shift option provides enhanced efficiency and smoother gear transitions, making it ideal for tasks requiring frequent speed adjustments, such as tilling or plowing in diverse terrains. The choice between these transmissions should be based on the specific requirements of the farming operations—more straightforward tasks may be well-suited for the 5-speed, whereas operations demanding greater adaptability will benefit from the power shift transmission.

TRANSMISSION 1
The Farmall 350 features a sliding gear transmission with 5 forward and 1 reverse gear, allowing for moderate speed versatility suited for various agricultural tasks. The dry disc clutch provides reliable engagement and disengagement, though it may require more maintenance than wet clutches in wet conditions. Ideal for medium-scale farming operations, this tractor excels in straightforward field work but may face challenges in heavy load scenarios or during frequent shifting operations.

| Gears | 5 forward and 1 reverse |
| Clutch | dry disc |
TRANSMISSION 2
The Farmall 350's Torque Amplifier (TA) allows for smooth, clutchless shifting between direct drive and increased torque modes, beneficial for varying field conditions. With 10 forward and 2 reverse gears, it provides flexibility for tasks requiring speed and power management, although the two-speed power shift might limit rapid acceleration compared to models with a more extensive range. This is particularly advantageous for operations needing high torque at low speeds, such as plowing or tilling, but may present challenges in scenarios requiring quick direction changes.

| Clutch | dry disc |
| Description | The Torque Amplifier (TA) provides a clutchless shift-on-the-move between normal, direct drive (DD) and the TA. By engaging the TA, tractor ground speed is reduced and torque is increased. |
MECHANICAL
The Farmall 350 tractor features a 4x2 2WD chassis which is suited for flat, stable terrains, potentially limiting traction in muddy conditions. The power steering enhances maneuverability, making it user-friendly for prolonged operations. Its 5-speed manual transmission combined with a 10-speed power shift provides versatility in speed and torque management, advantageous for various tasks such as tilling or hauling.
