YANMAR AF890 POWER
ENGINE DETAIL
The Yanmar AF890 is powered by a 4-cylinder, 4.4L Yanmar 4TNV106T diesel engine, delivering 90hp at 2400 RPM, making it suitable for medium to heavy-duty agricultural tasks. Its direct injection fuel system enhances fuel efficiency and lower emissions but may require more specific maintenance practices. The electric starter operating at 12 volts provides reliable operation, although reliance on electrical systems could be a potential challenge in isolated work environments without adequate power sources.

MECHANICAL
The Yanmar AF890 features a robust 4x4 MFWD (Mechanical Front Wheel Drive) system, enhancing traction on uneven terrain. Its 18-speed power shuttle transmission provides versatile speed options for various agricultural tasks, though potential complexity may challenge operators unfamiliar with multi-speed systems. The hydraulic wet disc brakes offer reliable stopping power, particularly beneficial in heavy-load scenarios, while the air-conditioned cab ensures operator comfort during long hours of operation.

YANMAR AF890 TIRES
The Yanmar AF890 tractor is equipped with standard agricultural tires, featuring a front size of 9.5-24 and a rear size of 13.6-38, which provides a good balance of traction and stability on uneven terrains. The larger rear tires enhance load-bearing capacity and reduce soil compaction, making it suitable for various farming applications. However, the specific tire sizes may limit maneuverability in tighter spaces or on narrower pathways.

DIMENSIONS & TIRES
The Yanmar AF890's wheelbase of 90.6 inches provides enhanced stability, making it suitable for both field and road operations. Weighing 7496 lbs, it offers substantial traction, particularly beneficial for heavy-duty tasks like plowing, but may pose challenges in soft or muddy terrain due to potential sinkage. Its tire specifications, with a narrower front (9.5-24) and wider rear (13.6-38), allow for better weight distribution and improved maneuverability in tight spaces.
