MECHANICAL
The David Brown Cropmaster Diesel tractor features a 4x2 2WD chassis, providing decent agility for light-duty tasks but may struggle on uneven terrain due to its lack of four-wheel drive. The manual steering and mechanical drum brakes offer simplicity and reliability, though they may require more physical effort from the operator and result in slower stopping power. The 4-speed and 6-speed gear transmission options allow for versatility in speed control, making it suitable for various tasks such as tilling or hauling, albeit with limited comfort in an open operator station.
