MECHANICAL
The Case 511-B tractor features a 4x2 2WD chassis, which provides simplicity and ease of maneuverability, ideal for flat terrain and lighter applications. Its manual steering and disc brakes are straightforward yet require more operator effort and awareness in navigating slopes or more challenging conditions. The transmission options (4-speed or 12-speed gear) offer versatility in speed control, making it suitable for various field tasks but may require skillful operation to exploit the full potential of either setup.
