Dimensions and Weight: Key Factors for Transport and Maneuverability of the 1999 John Deere 120 Excavator
The 1999 John Deere 120 Excavator has a transport weight of approximately 25,000 lbs (11,340 kg). Its overall length is 22 feet 10 inches (6.96 meters), width measures 8 feet 6 inches (2.59 meters), and height is 9 feet 9 inches (2.97 meters). These dimensions make it suitable for most standard transport options, though special permits may be required in some regions due to weight restrictions.
For maneuvering, the compact width and length allow for better access to confined work areas compared to larger models. The relatively low center of gravity enhances stability during loading, unloading, and on rough terrain, but the machine still requires adequate space for safe operation. When maneuvering in tight spots, the excavator’s size ensures flexibility but still demands careful planning to avoid obstructions or ground instability.
When transporting, confirm the trailer’s load capacity and secure fastening to prevent shifting. Given the 120’s weight, it’s critical to use the correct type of transporter for highway travel, ensuring all necessary clearance and compliance with local regulations.
