1, high cost: compared with ordinary wheeled tractors, crawler tractors are more expensive, and the purchase and maintenance costs are higher.
2. Difficult maintenance: It is difficult to maintain the crawler tractor, which requires frequent replacement of wearing parts such as crawler and crawler wheels, and requires high technical requirements for operation and maintenance.
3. Large turning radius: Because the track width of the crawler tractor is larger than the tire width, the turning radius is relatively large, which is not convenient for working in a narrow field.
4. Noise: When the crawler tractor is running, the friction between the crawler and the ground is large, which may affect the surrounding environment and the safety and health of people.
