ENGINE DETAIL

The Renault 85-12 tractor, powered by the MWM D226-4 diesel engine, features a robust 4.2L displacement, providing a balanced output of 78hp at 2350 RPM and a peak torque of 196.2 lb-ft at 1500 RPM, making it suitable for moderate agricultural tasks. The bore and stroke of 105x120 mm optimize combustion efficiency and torque characteristics, beneficial for tasks requiring sustained power delivery. Operators should consider the operational RPM range to ensure optimal performance and avoid excessive wear, particularly in heavy load scenarios.

RENAULT 85-12 ENGINE

The Renault 85-12 tractor is powered by a MWM 4.2L 4-cylinder diesel engine, offering a robust performance suitable for medium-duty agricultural tasks. With a substantial fuel tank capacity of 28.5 gallons (107.9 liters), it enables extended usage periods without frequent refueling, ideal for large-scale farming operations. However, operators should consider the maintenance complexity of the diesel engine, which may require more rigorous servicing compared to simpler gas engines.

TRANSMISSION

The Renault 85-12 tractor features a 12-speed transmission, allowing for versatile speed control and optimal torque management in various field conditions. This comprehensive gear range can enhance productivity by enabling precise operation in both forward and reverse, making it suitable for tasks like plowing, planting, and transport. However, the complexity of a multi-speed transmission may require practices for efficient operation, and operators must be familiar with the shifting patterns to maximize performance.

Gears

12 forward and reverse

MECHANICAL

The Renault 85-12, with its 4x2 2WD chassis, is optimal for lighter agricultural tasks and offers enhanced maneuverability on flat terrain. The hydrostatic power steering provides ease of handling, reducing operator fatigue during long hours. However, its dry disc brakes may require more maintenance compared to hydraulic systems, particularly in challenging conditions where mud and debris can accumulate.

RENAULT 85-12 TIRES

The Renault 85-12 tractor, equipped with 7.50-18 front tires and 16.9-34 rear tires, offers a balanced weight distribution, enhancing traction and stability during fieldwork. The rear tires, being wider, are advantageous for plowing and tillage tasks, while the front tires provide adequate steering responsiveness in various terrains. However, the narrower front tires may limit flotation in soft soils, potentially causing sinkage or losing traction under certain conditions.

DIMENSIONS & TIRES

The Renault 85-12 tractor features a relatively short wheelbase of 94.1 inches (239 cm), contributing to enhanced maneuverability in tight agricultural settings but potentially limiting stability on rough terrain. With a weight of 7,508 lbs (3,405 kg), it offers sufficient ballast for optimal traction, particularly when paired with larger rear tires (16.9-34), which can facilitate efficient tillage and transport tasks. However, the smaller front tires (7.50-18) may lead to challenges in front-end stability and load handling under heavy front-mounted implements.
