ENGINE DETAIL

The Steyr 9078 features a MWM WD 401.81 turbocharged diesel engine, providing a robust 78 hp and 220 lb-ft of torque at 1500 RPM, which ensures strong performance for heavy-duty tasks. The engine's 4.2L displacement, combined with a bore/stroke ratio of 105x120 mm, indicates efficient power delivery and good torque characteristics for activities like plowing and hauling. However, the rated RPM of 2300 may limit peak power for certain high-speed applications, making it more suited for low to mid-range operational efficiency in agricultural environments.

TRANSMISSIONS OVERVIEW

The Steyr 9078 tractor features a 16-speed synchronized transmission, allowing for smooth gear shifts and optimized power transfer across varied terrains. This enhances operational efficiency during both fieldwork and transportation, providing better control and reduced engine strain. However, operators may need to familiarize themselves with the precise shifting dynamics to fully utilize the transmission's capabilities.

TRANSMISSION 1

The Steyr 9078 features a synchronized transmission with 16 forward and 8 reverse gears, allowing for precise speed control and efficient maneuverability in varied terrain. The advantage of a synchronized gearbox is smoother gear shifts under load, enhancing overall operational efficiency. However, this system may require more maintenance compared to non-synchronized models, particularly in high-demand scenarios like heavy fieldwork or loader applications.

Gears	16 forward and 8 reverse

TRANSMISSION 2

The Steyr 9078 tractor features the Steyr-Power transmission, offering a total of 16 forward and reverse gears, which ensures fine control over speed and torque for various agricultural tasks. This extensive gear range particularly facilitates operations in diverse terrains, optimizing both efficiency and productivity. However, operators may require additional training to master the gear changes, particularly when navigating complex field conditions.

MECHANICAL

The Steyr 9078 features a versatile chassis with options for 2WD or 4WD, providing flexibility for different terrains and operational needs; the 4WD configuration enhances traction and stability in challenging conditions. The hydraulic wet disc brakes offer reliable stopping power and reduce maintenance compared to traditional brake systems, while the optional air-conditioning in the cab improves operator comfort during prolonged use. Its 16-speed synchronized transmission allows for efficient power management and adaptability across varying field tasks, though mastering the shifting can pose a learning curve for new operators.

STEYR 9078 TIRES

The Steyr 9078 is available in both 2WD and 4WD configurations, allowing for flexibility in traction depending on terrain. The 2WD version features standard agricultural tires that may limit off-road capabilities in muddy or uneven conditions. In contrast, the 4WD model, equipped with larger front and rear tires, enhances stability and traction, making it ideal for diverse agricultural tasks and challenging terrains.
