Crawler Tractor
70-90HP Crawler Tractor
Features
1. The 70-90HP crawler tractor is manufactured with fully enclosed cab. Heating system, air condition, and audio system are optional. Besides the broad vision, users can also enjoy the nice appearance and the comfortable operation.
2. For optimal trafficability and steering performance, this range of agricultural vehicle can be designed with rubber track.
3. The utilization of hydraulic power steering gear greatly reduces driver’s labor intensity.
4. To obtain good reliability, our rubber tracked crawler adopts simple beam structure for the final gear.
5. The new seal structure for the rear gear of our 70-90HP crawler tractor can reduce the steering oil intake.
6. The crawler tractor with cab adopts (4F+2R) sliding-gear transmission. The reasonable gear range makes it suitable for farmland and bulldozing.
7. Equipped with the diesel engine produced on the basis of British technology, our diesel crawler tractor is quite popular due to the large torque, powerful overload capacity, low fuel consumption, and environmental protection.
