ENGINES OVERVIEW

The International Harvester 856 tractor offers a robust 6.7L diesel engine, providing high torque for heavy-duty applications, making it ideal for agricultural tasks requiring sustained power. The alternative 4.9L gasoline and LP gas engines provide versatility and lower emissions, suitable for operators prioritizing fuel availability or environmental concerns. A potential challenge includes the weight of the diesel variant, which may limit mobility in soft soil conditions compared to the lighter gasoline or LP versions.

ENGINE DETAIL 1

The International Harvester 856 is powered by a D-407 diesel engine, offering robust performance with a displacement of 6.7L and a high compression ratio of 17:1, which enhances fuel efficiency and torque. Its dual dry air cleaner system provides superior filtration, beneficial for maintaining engine longevity in dusty conditions. However, the 2400 RPM rated speed may limit performance in certain high-demand applications; thus, optimal use is in medium to heavy agricultural tasks.

ENGINE DETAIL 2

The International Harvester 856 tractor is equipped with a C-301 gasoline engine, delivering a displacement of 301ci (4.9L) and a compression ratio of 7.7:1, optimizing torque and fuel efficiency at a rated RPM of 2400. Its dual dry air cleaner system enhances engine longevity by improving filtration, while the generous oil capacity of 9 quarts (8.5 L) allows for extended service intervals. However, the relatively low compression ratio may limit power output in comparison to diesel counterparts, making it suitable for lighter agricultural tasks and operations requiring lower fuel consumption.

ENGINE DETAIL 3

The International Harvester 856 tractor features a robust 301ci (4.9L) C-301 LP gas engine, providing effective power delivery at a rated RPM of 2400, compatible with a range of agricultural applications. The engine's compression ratio of 8.8:1 offers a balance between torque and fuel efficiency, while the dual dry air cleaner enhances engine longevity by effectively filtering out particulates. Challenges may include sourcing LP gas, which may not be as accessible in certain areas as traditional fuels, but the tractor's efficient oil (9 qts) and coolant (21.5 qts) capacities facilitate maintenance and reduce the frequency of oil changes.
