Engine

The engine is a MAN turbocharged intercooled diesel 6-cylinder liquid-cooled with a displacement of 757.9ci / 12.4L and bore/stroke of 4.96x6.54inches / 126x 166mm. It has a power output of 476hp / 355.0kW and is rated at 1700 RPM. The engine is equipped with selective catalytic reduction with diesel oxidation catalyst for Tier IV emissions control. The starter is electric and operates at 12 volts. The recommended oil change interval is 500 hours.

Transmission

The transmission is AccuDrive with infinite forward and reverse gears. The engine provides a claimed PTO power of 421hp / 313.9kW. The transmission is designed to work seamlessly with the engine to provide smooth and efficient power transfer. It is a reliable and durable transmission that can handle heavy loads and tough terrain.

Brakes

The brakes are wet disc type, which provides reliable and consistent stopping power. The MAN engine brake is also available to provide additional stopping power when needed. The emissions control system is selective catalytic reduction with diesel oxidation catalyst, which reduces harmful emissions and helps to protect the environment. The brake system is designed to be easy to maintain and service, with readily accessible components.

Steering

The steering is power-assisted, which provides easy and precise control of the tractor. The fuel tank has a capacity of 211.3 gallons / 799.8 liters, which provides ample fuel for long work sessions. The exhaust fluid (DEF) tank has a capacity of 22.5 gallons / 85.2 liters, which helps to reduce emissions and improve fuel efficiency. The MAN 12.4L 6-cylinder diesel engine provides plenty of power to handle heavy loads and tough terrain.

Common Problems

Users have reported issues with the cab suspension system, which can be prone to failure if not properly maintained. The wet disc brakes can also be prone to wear and require regular maintenance to ensure reliable performance. Some users have reported issues with the power steering system, which can be prone to leaks if not properly maintained. The engine can also be prone to overheating if not properly maintained, which can lead to reduced performance and increased fuel consumption.

What Users Like

Users appreciate the powerful and reliable MAN engine, which provides plenty of power to handle heavy loads and tough terrain. The AccuDrive transmission is also highly regarded for its smooth and efficient power transfer. The wet disc brakes provide reliable and consistent stopping power, and the power-assisted steering makes it easy to control the tractor. Users also appreciate the easy-to-use hydraulic system, which provides ample power to operate a wide range of implements and attachments.
