You want to drive your agricultural tractor with attached accessory equipment. What must you be aware of before driving off?

When operating an agricultural tractor with attached equipment, certain regulations must be followed to ensure safety and compliance with German traffic rules.

1. **Transport Position and Securing**: The accessory equipment must be in the transport position and properly secured. This is crucial because improperly positioned equipment can become a hazard on the road, potentially leading to accidents or damage.

2. **Maximum Gross Axle Weight Rating**: Observing the maximum gross axle weight rating is vital for both safety and legal compliance. If the weight exceeds the rated capacity, it can strain the vehicle, lead to brake failure, or cause tire blowouts, which presents a danger to the driver and other road users.

Understanding and adhering to these rules helps ensure safe driving conditions and prevents violations that may result in fines or other legal issues. The disengagement of single-wheeled brake pedals is not always relevant for all scenarios, hence it's not included in the correct answer for this situation.
