| Abstract: |
| The technological process and quality guarantee system of remanufactured agricultural caterpillar tractors were introduced in this paper, their economic and social benefits were analysed as well. The problems, which should be solved, in pushing the remanufacturing of agricultural tractors were proposed. Through the statistics of 128 used tractors, it was found that the usable parts and the worn parts, which can be repaired or modified by the new surface techniques, occupied 60.72% of the total parts, 61.55% of the total weight of tractors and 60.76% of the total prices. While the selling price of the remanufactured tractors was only 50%~60% of the new ones, and their life time was not less than 80% of the new machines. It indicated the important role of remanufacturing in the aspects of energy and materials-safety and environment protection. |
