VALMET 803 TIRES
The Valmet 803 tractor offers versatile configurations with both 2WD and 4WD options, enabling adaptability in varying agricultural conditions. The 2WD with standard tires (10.00-16 front and 16.9-34 rear) is suitable for lighter tasks and flatter terrain, while the 4WD configuration (13.6-28 front and 18.4-34 rear) enhances traction and stability, ideal for hills and muddy fields. When selecting between the two, consider the operational requirements; 4WD provides greater power distribution and can improve performance in challenging environments but may increase fuel consumption and maintenance needs.
