RENAULT 781S POWER
ENGINE DETAIL
The Renault 781S tractor is powered by a MWM D226-4 diesel engine featuring a 4-cylinder design with a displacement of 4.2L, offering 78hp at a rated RPM of 2350, which provides adequate power for moderate agricultural tasks. Its torque output of 199.2 lb-ft at 1500 RPM allows for effective performance during plowing and towing operations, making it beneficial for heavy-duty work. However, the relatively low RPM range may limit its suitability for high-speed applications, so it's best utilized in scenarios requiring consistent, robust torque rather than rapid operational speeds.

TRANSMISSION
The Renault 781S tractor features a 12-speed transmission, offering versatile gearing options for various terrain and workload scenarios. This allows for optimal torque management and fuel efficiency during field operations or transport tasks. However, managing such a wide range of gears may require additional operator skill to maximize performance and minimize fatigue.

12 forward and reverse |
MECHANICAL
The Renault 781S tractor features a 4x2 chassis with optional 4WD for enhanced traction in varying terrains, making it suitable for diverse agricultural tasks. Its hydrostatic power steering offers improved maneuverability, while the 12-speed transmission allows for versatile speed control, optimizing performance during fieldwork. However, the dry disc brakes may require more frequent maintenance compared to wet braking systems, which could be a consideration for long-term operational costs.

RENAULT 781S TIRES
The Renault 781S features Ag front tires sized 13.6-24 and Ag rear tires sized 16.9-34, providing a balanced footprint for improved traction and stability across various agricultural terrains. This tire configuration enhances the tractor's weight distribution, allowing for effective plowing and hauling tasks. However, the larger rear tires may limit maneuverability in confined spaces, making it less ideal for smaller farms or narrow crop rows.
