МТЗ 1221 Білорус

Powertrain and Performance Engineering

The core of the MTZ 1221 is its D-260.2 6-cylinder turbocharged diesel engine. With a displacement of 7.12 liters and a 15% torque backup, it provides the lugging power required for deep tillage and heavy-duty field operations. The pressurized liquid cooling system ensures thermal stability under high load in hot environments. This engine configuration focuses on durability and consistent performance in demanding agricultural cycles.

Transmission and PTO Versatility

The synchronized mechanical transmission provides 16 forward and 8 reverse speeds, allowing the operator to select the optimal ground speed for any implement. The hydraulic-actuated clutch ensures smooth engagement, reducing drivetrain stress during repetitive maneuvers. The rear Power Take-Off (PTO) features dual modes (540 and 1000 rpm), ensuring compatibility with everything from modern precision planters to high-output mowers.

Hydraulic Capacity and Chassis Strength

The hydraulic system is engineered for a lifting capacity of up to 4,500 kg at the hitch point. The force-position control regulator allows for precise depth maintenance, essential for high-yield seeding operations. The reinforced axle assemblies, featuring planetary-spur final drives, are designed to handle significant stress from heavy mounted and semi-mounted implements, ensuring long-term structural integrity.

Practical Advantages

• Serviceability: The straightforward design ensures that maintenance is intuitive and parts are globally available.
• Ballasting Flexibility: Provisions for front and rear weights allow for quick adjustment to balance the tractor based on the implement's weight.
• Operator Environment: The safety-rated cab features high-visibility glass and improved filtration, reducing operator fatigue during long working hours in the field.
