ENGINES OVERVIEW
The International Harvester 350 tractor offers versatile powertrain options with a Continental 3.2L diesel engine, International Harvester's 2.9L gasoline, and 2.9L LP gas engines, allowing it to cater to various operational needs. The diesel variant is advantageous for its fuel efficiency and torque, making it suitable for heavy-duty tasks, while the gasoline and LP options provide easier starting and lower emissions for lighter applications. However, users should consider the diesel’s additional maintenance requirements and the gasoline/LP engines' lower power output in demanding agricultural scenarios.

ENGINE DETAIL 1
The International Harvester 350 tractor is powered by a Continental D193 diesel engine with a moderate displacement of 193ci (3.2L) and a high compression ratio of 16.87:1, enhancing fuel efficiency and torque characteristics at the rated RPM of 2000. Its oil-bath air cleaner is advantageous for dusty environments, although it may require more maintenance than a dry-type filter. With a coolant capacity of 16 quarts, the tractor is designed for extended operations, although overheating could be a potential concern in rugged conditions without adequate maintenance.

ENGINE DETAIL 2
The International Harvester 350 features a C175 gasoline 4-cylinder engine with a displacement of 175ci (2.9L), providing a balance of power and efficiency for various agricultural tasks. Its low compression ratio of 7.0:1 at a rated RPM of 2000 may result in lower power output compared to higher-compression engines, but allows for smoother operation and reduced knocking in lower-quality fuels. The 6-volt starter system may present challenges in colder climates, and the 18qt (17.0L) coolant capacity supports effective engine temperature regulation, crucial for prolonged operation.

ENGINE DETAIL 3
The International Harvester 350 tractor is powered by a C175 LP gas engine, with a relatively small 2.9L displacement, providing adequate torque for moderate field operations while maintaining lower emissions compared to diesel counterparts. Its 9.0:1 compression ratio allows for efficient combustion at the rated RPM of 2000, making it suitable for longer working hours with reduced wear. However, the limitations in power output may require careful consideration of task suitability, particularly in heavy-duty applications or hilly terrains.

TRANSMISSION 2
The International Harvester 350 features a two-speed power shift transmission with 10 forward and 2 reverse gears, enabling versatility during various field operations. The Torque Amplifier (TA) enhances torque at lower speeds for challenging tasks while allowing seamless engagement without stopping. However, maintaining the dry disc clutch is crucial, as wear can affect the performance of both the clutch and TA system over time.
