NEW HOLLAND TN85A ENGINE
The New Holland TN85A tractor is powered by an Iveco 4.5L 4-cylinder diesel engine, providing a balance between power and fuel efficiency for medium-duty agricultural tasks. With a fuel tank capacity of 23.5 gallons (88.9L), it offers extended operational range, minimizing downtime for refueling during intensive work. However, the relatively smaller engine displacement may limit performance in extremely heavy-duty applications or steep terrains compared to larger alternatives.

TRANSMISSIONS OVERVIEW
The New Holland TN85A features a 12-speed or 16-speed partially synchronized transmission, offering operators flexibility in gear selection for various tasks, with mechanical or power shuttle for easier direction changes. The advantage of the 16-speed option lies in improved torque management and fuel efficiency during field operations. However, the complexity of the system may pose maintenance challenges, particularly for less experienced users.

TRANSMISSION 1
The New Holland TN85A features a Synchro Command transmission, providing 12 forward and reverse gears for versatile speed adaptation in various agricultural tasks. The partially synchronized gearbox, combined with a 280mm dry cerametallic clutch, allows for smooth gear changes but requires the operator to engage the clutch during shuttle operation, which may present a challenge in time-sensitive situations. Overall, this setup offers a balance between control and efficiency, making it suitable for operations needing frequent directional changes.

TRANSMISSION 2
The New Holland TN85A features a Synchro Command Plus transmission with 16 forward and reverse gears, providing versatile speed options for various tasks. The partially synchronized design enhances shifting ease while the mechanical shuttle, although requiring clutching, ensures durability with a robust 280mm dry cerametallic clutch plate. While this transmission system excels in agricultural applications for ease of operation, operators must be aware of the need for skillful clutch use during shuttle shifts to optimize performance.

TRANSMISSION 3
The New Holland TN85A tractor features a Synchro Command Plus transmission, providing 16 forward and reverse gears which enable smooth shifting for varied field applications. The left-hand clutchless power shuttle enhances operational efficiency, allowing the operator to switch directions quickly—ideal for tasks requiring frequent forward and reverse motions, such as loader work. However, the six wet organic plates clutch may present durability challenges under heavy mechanical stress, necessitating careful management of load conditions.

DIMENSIONS & TIRES
The New Holland TN85A tractor, available in both 2WD and 4WD configurations, has a notable weight range of 6008 to 6118 pounds, which enhances stability and traction, particularly in the 4WD variant. The 2WD wheelbase of 86.7 inches provides a longer footprint for improved load distribution, while the shorter 4WD wheelbase of 83.7 inches allows for better maneuverability in tight spaces. Ideal for medium to large farming operations, the TN85A excels in diverse tasks but may pose challenges in softer soil conditions due to its heavier weight.
