A comparative analysis of the John Deere 9970 and CP570 models was carried out regarding the work productivity and harvesting efficiency of the machinery used in cotton harvesting.
The analysis took the machine's work productivity, harvesting efficiency, cotton unloading, transportation, and storage processes as the main criteria.
According to the data, the 9970 cotton harvester can harvest an average of 1 hectare of land per hour. In the CP570, this indicator is 2 hectares.
Based on a 10-hour working day, the 9,970 machine harvests approximately 25 tons of cotton from 10 hectares of land, while the CP570 is shown to harvest up to 50 tons from 20 hectares. For both machines in the comparison, the average yield of the field was taken as 2.5 tons/hectare.
It is also stated that during the 30-day optimal harvesting period, the 9970 model can harvest 750 tons from 300 hectares, and the CP570 can harvest 1500 tons from 600 hectares. The document notes that the CP570 has the ability to harvest the field twice as fast compared to the 9970 in the same amount of time.
There is also a difference in harvesting units. While the 9970 model has a total of 1,728 spindles, this indicator is 2,440 in the CP570. The analysis emphasized that the CP570 has a high harvesting potential and losses are at a minimal level.
There is also a difference between the two models in the process of unloading cotton. In the 9970, when the basket is full, it is required to stop the machine and unload the cotton. The document notes that each such stop lasts at least 15–20 minutes. In the CP570, cotton rolls are formed during the harvesting process and unloaded without stopping the movement of the machine.
The advantages of the CP570 from the point of view of logistics and storage are also mentioned. Working with the 9970 requires up to 4–6 workers for each cotton harvester, while the CP570 shows 1 operator and 1 tractor driver — a total of 2 employees.
The document notes that the process of transporting and storing the cotton rolls formed in the CP570 also allows for resource savings.
According to the presented analysis, the CP570 demonstrates higher performance than the 9970 model in terms of work productivity, harvesting volume, continuous operation, and logistics processes.
