ENGINES OVERVIEW
The Oliver 2655 tractor features two engine options: a 9.6L 6-cylinder diesel and an 8.3L 6-cylinder LP gas engine. The diesel variant provides higher torque and better fuel efficiency, making it ideal for heavy-duty tasks such as plowing and tilling in tough field conditions. Conversely, the LP gas version offers cleaner emissions and quieter operation, which may benefit applications in residential or urban settings but may have limited torque compared to the diesel option.

ENGINE DETAIL 1
The Oliver 2655 tractor is powered by a robust Minneapolis-Moline 6-cylinder diesel engine with a displacement of 9.6L, offering 169 hp at a rated speed of 2200 RPM, making it suitable for heavy-duty agricultural tasks. Its 15.3:1 compression ratio enhances fuel efficiency, although it may also lead to increased engine stress under prolonged heavy loads. The dual paper air cleaner promotes better filtration, potentially extending engine life, while a coolant capacity of 33 qts ensures effective thermal management during extended operations.

ENGINE DETAIL 2
The Oliver 2655 tractor is powered by a Minneapolis-Moline LP gas 6-cylinder engine with a significant displacement of 504 ci (8.3L), offering robust power output of 169 hp at a rated RPM of 2200. Its bore and stroke dimensions (4.625 x 5.00 inches) suggest an engine designed for torque, making it suitable for heavy-duty applications such as tilling or hauling. A potential challenge is sourcing LP gas fuel, which may limit refueling options in rural areas compared to conventional diesel tractors.

OLIVER 2655 ENGINES
The Oliver 2655 tractor features a robust Minneapolis-Moline 9.6L 6-cylinder diesel engine, providing high torque and fuel efficiency, ideal for heavy-duty agricultural tasks. Alternatively, the 8.3L 6-cylinder LP gas engine offers cleaner emissions and operates quieter, making it suitable for applications sensitive to noise pollution. Consider the diesel's advantages in power and longevity against the LP gas model's benefits of reduced environmental impact and operating costs, depending on your operational focus.

TRANSMISSION
The Oliver 2655 tractor features a 10-forward and 2-reverse gear configuration with a dry disc clutch, allowing for smooth transitions between gear changes. The five gears in both low and high ranges provide versatility in speed and torque management, making it suitable for various agricultural tasks. However, the limited reverse gears may pose challenges for maneuverability in tight spaces, emphasizing the need for careful operational planning.

MECHANICAL
The Oliver 2655 tractor features a 4x4 articulated 4WD chassis, providing excellent traction and maneuverability in diverse agricultural terrains, which is advantageous for fieldwork and hauling tasks. The hydrostatic power steering enhances ease of use and reduces operator fatigue during prolonged operations; however, maintenance may be more complex than traditional systems. The 10-speed transmission allows for versatile speed control, facilitating optimal performance across various applications but may require skillful gear management when navigating mixed terrains.

OLIVER 2655 TIRES
The Oliver 2655 tractor, equipped with 18.4-34 agricultural tires both at the front and rear, offers enhanced stability and traction on diverse terrains, making it suitable for heavy-duty fieldwork and transport tasks. However, the larger tire size may limit maneuverability in tight spaces and increase soil compaction. Optimal scenarios include row crop applications, where the balance between horsepower and tire footprint can maximize productivity without excessive tire slippage.

DIMENSIONS & TIRES
The Oliver 2655 features a wheelbase of 120 inches, providing stability and a smooth ride, especially in field operations. Weighing 19,850 lbs enhances traction, making it suitable for heavy-duty tasks like plowing and hauling; however, this significant weight may limit maneuverability in tighter spaces. The uniform 18.4-34 tire size offers good flotation and soil compaction control but may require careful attention to tire pressure to prevent soil damage during prolonged use.
