Stability Factor (\( K = \frac{F_w \times W_b}{P \times h} \)):

Where:

• \( K \) is the stability factor, with a minimum value of 1.25.
• \( F_w \) is the static front end weight, in kg.
• \( W_b \) is the wheel base.
• \( P \) is the maximum drawbar pull parallel to the ground, in kg.
• \( h \) is the height of the static line of pull perpendicular to the ground.
