ENGINES OVERVIEW
The Oliver 2055 tractor is powered by either an 8.3L 6-cylinder diesel engine or an LP gas variant, offering flexibility depending on fuel availability and operational costs. While the diesel option typically provides better torque and fuel efficiency for heavy-duty applications, the LP gas engine may have lower emissions and reduced fuel costs in certain scenarios. Consider the specific tasks and fuel access in your operation to choose the most suitable engine type.

ENGINE DETAIL 1
The Oliver 2055 tractor features a robust Minneapolis-Moline 6-cylinder diesel engine with a significant displacement of 504ci (8.3L), providing ample torque for heavy-duty applications. Its bore and stroke configuration (4.625x5.00 inches) promotes torque delivery at the rated RPM of 1800, making it suitable for agricultural tasks requiring sustained power. However, maintenance considerations include a relatively high oil (13 qt) and coolant (33 qt) capacity, which may increase service intervals and costs; ideal for operators needing reliable performance over extended periods.

ENGINE DETAIL 2
The Oliver 2055 tractor features a robust Minneapolis-Moline LP gas 6-cylinder engine with a significant displacement of 504ci (8.3L) and a compression ratio of 8.8:1, which offers a balance between power output and fuel efficiency. With a rated RPM of 1800, the tractor is designed for steady torque delivery, ideal for heavy-duty applications such as plowing or pulling. However, the dry air cleaner may require more frequent maintenance in dusty conditions compared to oil-bath systems, potentially impacting operational efficiency in adverse environments.
