ЮМЗ 6АЛ

Engineering Foundation and Drivetrain

The YUMZ 6AL is built on a robust semi-frame chassis, designed to withstand the torsional stress of intensive agricultural tasks. At its heart lies the D-65 diesel engine, renowned for its high torque output at low RPM. This characteristic is essential for sustained drawbar work, such as plowing heavy clay soils. The cooling and lubrication systems were engineered for reliability in field conditions, prioritizing simplicity and accessibility for field maintenance.

Transmission and Torque Transfer

The mechanical multi-speed gearbox of the YUMZ 6AL is optimized for efficient power delivery from the crankshaft to the drive wheels. It utilizes a single-disc, dry-type clutch, providing consistent engagement even under heavy loads. The rear axle assembly is reinforced, ensuring that the tractor can handle significant mounted implements without structural failure, maintaining balance and traction during field operations.

Hydraulic Performance

The YUMZ 6AL features a unit-type hydraulic system powered by a gear-driven pump. This setup provides the constant pressure required for precise control of three-point hitch implements. The valve-distributor mechanism is designed for durability and allows for fine adjustment of tillage equipment depth, which is critical for consistent agricultural results. The system is straightforward, reducing downtime and simplifying repairs.

• Tractive Class: 1.4, balanced for versatile utility in medium-sized farms.
• Steering: Mechanical worm gear steering system that provides direct, reliable feedback from the front wheels.
• PTO: Two-speed independent power take-off (540 and 1000 RPM) to accommodate a variety of active implements, including cutters and sprayers.
