Tyre dimensions according to STRO norms.
Masses
With tyres 600/65R28, 710/70R38
Total mass with full fuel tank and without ballast weights (kg) 7300
Front axle mass (kg) 2920 (40%)
Rear axle mass (kg) 4380 (60%)
Maximum permissible axle loading
The data is valid for tractors with standard track widths and regardless of tyre limitations.
DANGER: In offroad conditions, the allowed driving speed with maximum front axle loading is 10 km/h.
If the driving speed is faster than this in offroad conditions, the allowed front axle loading is smaller.
Maximum front axle loading at maximum driving speed (kg) 5500
Maximum front axle loading at working conditions: offroad and with
driving speed 10 km/h (kg)
8500
Maximum rear axle loading (kg) 9000
Total weight (kg) 13 500
NOTE: The permissible wheel load can reduce the maximum permissible axle load.
IMPORTANT: On 50 km/h models and when driving at the maximum speed, the tyre loading is smaller. For
information on tyre pressure, see the tyre manufacturer's catalogue.
