This study investigates the effect of slope angle and forward operating speed on the optimal performance of the harvesting process of a combine equipped with a decelerating pendulum device that mechanically and hydraulically changes the angle of inclination of the combine. Three harvesting slope angles (0-5°, 10-15° and 20-25°) and three forward speeds (3, 5 and 7 km/h) were tested using a New Holland TC54 harvester. The experiment was carried out using a randomised complete block design (RCBD) with (27) experimental units distributed in three replications. Several key performance indicators were measured including: Fuel consumption (litres/hour), operational efficiency (%), harvester stability and total grain loss as a percentage. The results showed that soils with steeper slopes significantly increased fuel consumption and grain loss, while reducing machine stability. The best performance was achieved at a slope angle of (10-15°) and a speed of (5) km/h, with a field capacity of (5.60) tons/hour, fuel consumption of 24.10 liters/hour, and the lowest grain loss of (2.3%). The effects of slope and speed were found to be statistically significant (P < 0.05), reflecting the importance of improved combinations in significantly enhancing operational efficiency, reducing harvest losses, and thus improving the overall performance of the agricultural system.

Conclusion

The findings of this study demonstrate that both slope angle and forward speed significantly influence the performance of combine harvesters equipped with pendulum-based stabilization systems.Steeper slopes resulted in higher fuel use and reduced machine stability, increasing grain loss.Moderate slope angles yielded optimal performance, with the highest effective field capacity and acceptable fuel consumption.Operating at 5 km/h offered the best balance between productivity and energy efficiency.The optimal configuration of a 10–15° slope at 5 km/h can significantly improve harvesting outcomes, minimizing grain loss and fuel use while enhancing operational capacity.

Future Research

Penelitian lebih lanjut perlu dilakukan untuk mengeksplorasi pengaruh jangka panjang dari penggunaan sistem pendulum terhadap keausan mekanis mesin pemanen, serta efisiensi energi dan respons tanaman terhadap berbagai kondisi kemiringan dan kecepatan. Selain itu, pengembangan sistem kontrol adaptif berbasis sensor yang dapat secara otomatis menyesuaikan parameter operasi mesin pemanen berdasarkan kondisi medan secara *real-time* dapat meningkatkan efisiensi dan mengurangi kehilangan hasil panen. Terakhir, studi komparatif antara berbagai desain sistem pendulum dan dampaknya terhadap kinerja mesin pemanen pada berbagai jenis tanah dan iklim juga perlu dilakukan untuk mengidentifikasi solusi yang paling efektif dan berkelanjutan bagi petani.
