1977 Zetor SMRF3AXXX5NO Diesel · TUX 821S

The vehicle is currently roadworthy, having passed its most recent inspection in October 2025 with no recorded defects. The maintenance trend shows an area of improvement following a significant mechanical failure in late 2022. While the most recent report suggests a clean bill, the history indicates a period of structural concern that required attention, showing that the current or previous owner has addressed specific chassis-related issues over the last two years. Data regarding mileage is entirely absent, making it impossible to determine the usage patterns or the age of mechanical components. Without mileage figures to compare against the test dates, I cannot verify if the vehicle is used regularly or has sat stationary for long periods. This lack of information prevents an assessment of wear and tear on the engine or drivetrain relative to the tractor's age. A physical inspection must focus heavily on the structural integrity of the chassis and cross members. The 2023 and 2024 tests specifically flagged corrosion on these load-bearing components, and although the vehicle passed in 2025, the buyer should check for scaling rust, thinning metal, or poor repairs in these areas to ensure corrosion has not progressed since the last test. The failure in September 2022 due to insufficient brake effort and axle imbalance also suggests that the braking system was previously neglected. You should verify the condition of the brake cylinders, drums, and lines to ensure the system remains effective and free of leaks or seized pistons.
